CBS CORP. BUSINESS SEGMENTS

        Entertainment (53%, 54% and 49% of the Company's consolidated revenues in 2010, 2009 and 2008, respectively)

        The Entertainment segment consists of the CBS Television Network; CBS Television Studios, CBS Studios International and CBS Television Distribution, the Company's television production and syndication operations; CBS Films, the Company's producer and distributor of theatrical motion pictures; and CBS Interactive, the Company's online content networks for information and entertainment.

        Television Network.    The CBS Television Network through CBS Entertainment™, CBS News® and CBS Sports® distributes a comprehensive schedule of news and public affairs broadcasts, sports and entertainment programming to more than 200 domestic affiliates reaching throughout the U.S., including 16 of the Company's owned and operated television stations, and to affiliated stations in certain U.S. territories. The CBS Television Network primarily derives revenues from the sales of advertising time for its network broadcasts.

        CBS Entertainment is responsible for acquiring or developing and scheduling the entertainment programming presented on the CBS Television Network, which includes primetime comedy and drama series, reality-based programming, specials, children's programs, daytime dramas, game shows and late-night programs. CBS News operates a worldwide news organization, providing the CBS Television Network and the CBS Radio Network™ with regularly scheduled news and public affairs broadcasts, including 60 Minutes®, CBS Evening News with Katie Couric and The Early Show, as well as special reports. CBS News Productions, the off-network production company created by CBS News, produces programming for domestic and international outlets, including the CBS Television Network, cable television, home video, audio-book and in-flight markets, as well as schools and libraries. CBS News also provides CBS Newspath®, a television news syndication service that offers daily news coverage, sports highlights and news features to the CBS Television Network affiliates and other subscribers worldwide. CBS Sports broadcasts include The NFL Today, certain games from the NCAA Division I Men's Basketball Tournament, including the NCAA Men's Final Four, golf, including the Masters Tournament and the PGA Championship, the U.S. Open Tennis Championships, regular-season college football and basketball line-ups on network television, in addition to the NFL's American Football Conference regular season schedule, the Postseason Divisional Playoff games and the AFC championship game. CBS Sports has rights extensions with the NFL to broadcast the AFC through the 2013 season including the broadcast of the 2013 Super Bowl. CBS Home Entertainment licenses home video rights and CBS Consumer Products licenses merchandising rights.

        The CW, a broadcast network and the Company's 50/50 joint venture with Warner Bros. Entertainment, was launched in Fall 2006. The CW's programming includes Gossip Girl, 90210, The Vampire Diaries and America's Next Top Model. Nine of the Company's owned television stations are affiliates of The CW.

        Television Production and Syndication.    The Company, through CBS Television Studios, CBS Studios International and CBS Television Distribution, produces, acquires and/or distributes programming worldwide, including series, specials, news and public affairs. Such programming is produced primarily for broadcast on network television, exhibition on basic cable and premium subscription services or distribution via first-run syndication. First-run syndication is programming exhibited on television stations without prior exhibition on a network or cable service. The Company also distributes off-network syndicated programming, which is programming exhibited on television stations or cable networks following its exhibition on a network, basic cable network or premium subscription service.

        Programming that was produced or co-produced by the Company's production group and is broadcast on network television includes, among others, CSI: Crime Scene Investigation (CBS), NCIS (CBS), The Good Wife (CBS) and 90210 (The CW). Generally, a network will license a specified number of episodes for broadcast on the network in the U.S. during a license period. Remaining distribution rights, including foreign and/or off-network syndication rights, are typically retained by the Company or, in the case of co-productions, distribution rights are shared with the co-producer for U.S. or foreign markets. The network license fee for a series episode is normally lower than the costs of producing the episode; however, the Company's objective is to recoup its costs and earn a profit through international and domestic syndication of episodes. International sales are generally made within one year of U.S. network run. Generally, a series must have a network run of at least three or four years to be successfully sold in domestic syndication. In off-network syndication, the Company distributes series such as CSI:, CSI: Miami, CSI: NY, Numb3rs, Criminal Minds and NCIS as well as a library of older television programs. The Company also produces and/or distributes first-run syndicated series such as Jeopardy!, Entertainment Tonight, Inside Edition, The Insider, Dr. Phil, Rachael Ray and Judge Judy. The Company also distributes syndicated programming internationally.

        License fees for completed television programming in syndication and on cable are recorded as revenues in the period that the products are available for exhibition, which, among other reasons, may cause substantial fluctuation in the Entertainment segment's operating results. Unrecognized revenues attributable to such license agreements were approximately $654.1 million and $387.0 million at December 31, 2010 and December 31, 2009, respectively.

        The Company continues to expand its global channel presence through new international joint ventures. In 2010, the Company entered into a 50-50 joint venture with Reliance Broadcast Network Limited to create three new English language general entertainment television channels customized for the Indian market and surrounding territory, the first of which, BIG CBS Prime™, launched in November 2010. Also, in 2010, the Company and a subsidiary of Ten Network Holdings Limited entered into a joint venture to provide content to ELEVEN™, a digital multichannel service which launched in Australia in January 2011. The Company owns an approximately 33% interest in this venture. In addition, the Company owns a 50% interest in a joint venture with Chellozone (UK) Limited, a subsidiary of Liberty Global, Inc., which owns and operates six television channels in the U.K. and Ireland, including CBS Action™, CBS Drama™ and CBS Reality™; and an approximately 33% interest in a joint venture, which owns two pay television channels in Australia called TV1 and Sci Fi.

        CBS Films.    CBS Films was created in September 2007 to produce and distribute theatrical motion pictures across all genres. The budget for each picture is intended to be up to $50 million in addition to advertising and marketing costs at a level consistent with industry custom. The majority of motion pictures produced or acquired by CBS Films is intended for a wide, commercial theatrical release, similar to motion pictures typically produced and released by major studios. CBS Films' U.S. theatrical releases in 2010 included Extraordinary Measures, The Back-up Plan, and Faster, which is a co-production with an affiliate of Sony Pictures Entertainment. U.S. theatrical releases in 2011 include The Mechanic, and Beastly, which is expected to be released in March 2011.

        In general, motion pictures produced or acquired by CBS Films are exhibited theatrically in the U.S. and internationally, followed by exploitation via home entertainment (including DVD and electronic sell-through), video-on-demand, pay-per-view, pay television, free television and basic cable, digital media outlets and, in some cases, other exhibitors such as airlines and hotels. CBS Films will exploit its motion pictures (including certain ancillary rights, such as licensing and merchandising) and generate revenues in all media in the relevant release windows worldwide either directly, through affiliated CBS entities, or via third party distribution arrangements.

        CBS Interactive.    CBS Interactive operates one of the leading online content networks for information and entertainment. CBS Interactive was ranked among the top Internet properties in the world according

to comScore Media Metrix, December 2010. CBS Interactive's leading brands, including CNET, CBS.com, CBSSports.com, GameSpot, TV.com, BNET and CHOW, among others, serve targeted audiences with text, video, audio, and mobile content spanning technology, entertainment, sports, news, business, gaming and music categories. In addition to its U.S.-based business, CBS Interactive operates in Asia and Europe. CBS Interactive's worldwide brands reached approximately 256.0 million unique monthly visitors during December 2010.

        CBS Interactive generates revenue principally from the sale of advertising and sponsorships, in addition to fees derived from search and commerce partners, licensing fees, subscriptions, e-commerce activities, and other paid services. Advertising spending on the Internet, as in traditional media, fluctuates significantly with economic conditions. In addition, online marketing spending follows seasonal consumer behavior throughout the calendar year to reflect trends during the calendar year.

        CNET.com is one of the leading Web sites for technology and consumer electronics information. GameSpot is one of the leading gaming information Web sites according to comScore Media Metrix, December 2010. GameSpot's content includes video game reviews and previews, news, Webcasts, videos, online tournaments and game downloads. CBSSports.com provides sports content, fantasy sports, community and e-commerce features. CBSSports.com owns and operates CBSCollegeSports.com College Network and MaxPreps.com. In 2010, CBSSports.com hosted the NCAA March Madness on demand video player that provided live streaming video of the NCAA Division I Men's Basketball Championship. TV.com is a leading destination for entertainment and community around television where visitors can watch videos and discuss and obtain information about television shows across all networks. CBS Business Network, which is composed of BNET.com and CBS MoneyWatch.com, is a leading business media site, offering award-winning original content, as well as one of the largest business libraries available on the Internet. CBS Interactive also operates CBS.com, the online destination for CBS Television Network programming. Through the CBS Audience Network™, the Company delivers content from its Web sites and television, radio and affiliated stations, through new and existing advertiser-supported deals. The growing slate of CBS entertainment, news and sports content available includes full episodes, clips and highlights based on CBS and Showtime Networks programming as well as original made-for-the-Web content.

Entertainment Competition.

        Television Network.    The television broadcast environment is highly competitive. The principal methods of competition in broadcast television are the development and acquisition of popular programming and the development of audience interest through programming and promotion, in order to sell advertising at profitable rates. Broadcast networks like CBS compete for audience, advertising revenues and programming with other broadcast networks such as ABC, FOX, NBC, The CW and MyNetworkTV, independent television stations, cable program services as well as other media, including DVDs, print and the Internet. In addition, the CBS Television Network competes with the other broadcast networks to secure affiliations with independently owned television stations in markets across the country, which are necessary to ensure the effective distribution of network programming to a nationwide audience. According to Nielsen Media Research, for the broadcast television primetime daypart for the period September 20, 2010 to February 6, 2011, the CBS Television Network secured the #1 position for total viewers and for key adult viewers ages 25-54 and the #2 position for adult viewers ages 18-49.

        Television Production and Syndication.    As a producer and distributor of programming, the Company competes with studios, television production groups, and independent producers and syndicators such as Disney, Sony, NBC Universal, Warner Bros. and Fox to produce and sell programming both domestically and overseas. The Company also competes to obtain creative talent and story properties which are essential to the success of all of the Company's entertainment businesses.

        CBS Films.    Motion picture production and distribution is a highly competitive business. During the life cycle of the development and production of a motion picture project, CBS Films must compete for the

I-4

rights to compelling underlying source material and talent such as writers, producers, directors, on screen performers and other creative personnel. Once a motion picture is completed, CBS Films must compete with numerous other motion pictures produced by various studios and independent producers including Paramount Pictures Corporation, Walt Disney Studios Motion Pictures, Warner Bros. Entertainment, Inc., Lionsgate Entertainment, Summit Entertainment, LLC, The Weinstein Company, Metro-Goldwyn-Mayer Studios Inc. and Lakeshore Entertainment Group LLC, among others, for audience acceptance as well as limited exhibition outlets across all of the relevant release windows. In addition, the ultimate consumer has many options for entertainment other than motion pictures including video games, sports, travel, outdoor recreation, the Internet, and other cultural and computer-related activities.

        CBS Interactive.    CBS Interactive competes with a variety of online properties for users, advertisers, and partners, including the following: general purpose portals such as AOL, MSN and Yahoo!, especially as these properties expand their content offerings; search engines such as Google, Yahoo! and MSN; online comparison shopping and retail properties, including Shopping.com, Amazon.com and eBay; vertical content sites in the categories that CBS Interactive's brands serve, such as technology, gaming, music, news, business, food, and lifestyle focused Web sites; and platforms such as blogs, podcasts and video properties. CBS Interactive also competes for users and advertisers with diversified media companies that provide both online and offline content, including magazines, cable television, network television, radio and newspapers.

        Cable Networks (10%, 10% and 9% of the Company's consolidated revenues in 2010, 2009 and 2008, respectively)

        The Cable Networks segment is composed of Showtime Networks, the Company's premium subscription program services; CBS College Sports Network, the Company's cable network devoted to college athletics; and Smithsonian Networks, a venture with Smithsonian Institution, which operates Smithsonian Channel.

        Showtime Networks.    Showtime Networks owns and operates three commercial-free, premium subscription program services in the U.S.: Showtime, offering recently released theatrical feature films, original series, documentaries, boxing, mixed martial arts and other sports-related programming, and special events; The Movie Channel®, offering recently released theatrical feature films and related programming; and Flix®, offering theatrical feature films primarily from the last several decades, as well as selected other titles. At December 31, 2010, Showtime, The Movie Channel and Flix, in the aggregate, had approximately 67.1 million subscriptions in the U.S., certain U.S. territories and Bermuda.

        Showtime Networks also owns and operates multiplexed channels of Showtime and The Movie Channel in the U.S. which offer additional and varied programming choices. In addition, Showtime Networks transmits high definition feeds of Showtime, The Movie Channel and many of their multiplexed channels, and also makes versions of Showtime, The Movie Channel and Flix available "on demand," enabling subscribers to watch selected individual programs at their convenience (in both standard and high definition in the case of Showtime and The Movie Channel, and standard definition in the case of Flix). In October 2010, Showtime Networks announced its plans to launch Showtime Anytime™, a new video-streaming version of Showtime to be available via the Internet free of charge to Showtime subscribers as part of their Showtime subscription through participating Showtime Networks' cable, direct broadcast satellite ("DBS") and telephone company ("telco") distributors. Showtime Networks also operates the Web site SHO.com and various mobile applications which promote Showtime, The Movie Channel and Flix programming, and provide information and entertainment and other services.

        Showtime Networks derives revenue principally from the license of its program services to numerous cable, DBS, telco, and other distributors, with a substantial portion of such revenue coming from three of the largest such distributors. The costs of acquiring exhibition rights to programming and producing original series are the principal expenses of Showtime Networks. Showtime Networks enters into commitments to acquire rights, with an emphasis on acquiring exclusive rights for Showtime and The Movie

I-5

---

Channel, from major or independent motion picture producers and other distributors typically covering the U.S. and Bermuda for varying durations. For example, in addition to a motion picture output agreement with CBS Films, Showtime Networks has entered into motion picture output agreements with Buena Vista Pay Television, a subsidiary of The Walt Disney Company, for certain DreamWorks motion pictures, The Weinstein Company and Summit Entertainment for the exclusive U.S. premium subscription television rights for certain exhibition windows relating to feature films initially theatrically released in the U.S through December 2015 and, in the case of Summit Entertainment, December 2012. Showtime Networks' original series include Dexter®, Californication, Nurse Jackie, Shameless, The Big C, The Borgias (premiering in April 2011), Weeds and United States of Tara®, among others. Showtime Networks has entered into and may from time to time enter into co-financing, co-production and/or distribution arrangements with other parties to reduce the net cost to Showtime Networks for its original programming. In addition, Showtime Networks derives revenue by licensing rights it retains in certain of its original programming. For example, Showtime Networks and its corporate affiliate(s) have entered into licenses with television networks in various territories for exhibition of certain original series, as well as electronic sell-through arrangements with several Internet distributors, including iTunes and Amazon, among others, for certain Showtime programming. Showtime Networks also produces and/or provides special events to licensees on a pay-per-view basis through Showtime PPV®.

        Showtime Networks also owns a majority of and manages Smithsonian Networks, a venture with Smithsonian Institution, which operates Smithsonian Channel™, a basic cable service in the U.S., featuring programs of a cultural, historical, scientific and educational nature. Smithsonian Networks has launched both standard and high definition versions of Smithsonian Channel, as well as of its companion on demand version.

        CBS College Sports Network.    CBS College Sports Network is a 24-hour cable program service dedicated to college sports. The network features events from approximately 15 men's and women's college sports and provides coverage of over 250 live events each year in addition to live studio shows and original programming. CBS College Sports Network had approximately 39.1 million subscribers as of December 31, 2010. The network derives its revenues from subscription fees and the sale of advertising time on its cable program service. CBS College Sports Network and Comcast Corporation each owns a 50% interest in the mtn: MountainWest Sports Network, which exhibits Mountain West Conference athletics and is available to U.S. cable and satellite providers.

Cable Networks Competition.

        Showtime Networks.    Showtime Networks primarily competes with other providers of premium subscription program services in the U.S.: Home Box Office, Inc. and Starz Entertainment, LLC. Competition among premium subscription program services in the U.S. is dependent on: (i) the production, acquisition and packaging of original series and other original programming and the acquisition and packaging of an adequate number of recently released theatrical motion pictures; and (ii) the offering of prices, marketing and advertising support and other incentives to cable, DBS, telco and other distributors for carriage so as to favorably position and package Showtime Networks' premium subscription program services to subscribers. Home Box Office, Inc. is the dominant company in the U.S. premium subscription program service category, offering two premium subscription program services, HBO and Cinemax. Showtime Networks competes with Home Box Office, Inc. and has a smaller share of the premium subscription program service category. Starz Entertainment, LLC owns Starz, another premium subscription program service, which competes with Showtime Networks' and Home Box Office, Inc.'s premium program services. Showtime Networks also competes for programming, distribution and/or audiences with broadcast television, basic cable program services and other media, including DVDs, portable devices and the Internet.

I-6

---

        The terms and favorable renewal of agreements with distributors for the distribution of the Company's subscription program services are important to the Company. Consolidation among multichannel video programming distributors and other marketplace factors make it more difficult to reach favorable terms and could have an adverse effect on revenues. In addition, new entrants, such as Netflix, Inc., providing programming or other services for cable and/or other platforms, including the Internet, are or could be competitive with and adversely affect the Company's media businesses, including Showtime Networks' subscription program service business.

        Smithsonian Networks competes for programming, distribution and/or audiences with non-fiction and other basic cable program services, including Discovery Channel, National Geographic Channel and History, as well as with broadcast television and other media, such as DVDs, portable devices and the Internet.

        CBS College Sports Network.    CBS College Sports Network's cable programming service principally competes with other sports-oriented cable programming services for cable, DBS and telco distribution and related revenue, for viewership and for advertising revenue. Consolidation among cable operators has made it more difficult for newer channels to secure broad distribution. In addition, the largest cable providers have created sports tiers for newer sports programming services which have not, in many cases, achieved significant subscriber penetration or acceptance. CBS College Sports Network's television service also competes with other sports programming services, such as ESPN and the FOX Sports Networks, in acquiring the television and multimedia rights to sporting events, resulting in increased rights fees and increased production expenses. CBS College Sports Network will be renamed CBS Sports Network in April 2011.

        Publishing (6% of the Company's consolidated revenues in each of 2010, 2009 and 2008)

        The Publishing segment consists of Simon & Schuster, which publishes and distributes consumer books in the U.S. and internationally.

        Simon & Schuster publishes and distributes adult and children's consumer books in printed, audio and digital formats in the U.S. and internationally. Digital formats include audio downloads for the Apple iPod and MP3 players, electronic books for increasingly popular devices such as Amazon's Kindle, the Apple iPad and Barnes & Noble's NOOK, stand-alone applications for the Apple iPod and iPhone, and new hybrid text and video combinations. Simon & Schuster's major adult imprints include Simon & Schuster, Pocket Books, Scribner, Atria Books®, Gallery Books™, Touchstone® and Free Press. Simon & Schuster's major children's imprints include Simon Pulse®, Aladdin® and Simon & Schuster Books For Young Readers™. Simon & Schuster also develops special imprints and publishes titles based on the CBS Television Network's and Showtime Networks' products as well as that of third parties and distributes products for other publishers. Simon & Schuster distributes its products directly and through third parties. Simon & Schuster also delivers content and promotes its products on general Internet sites as well as those linked to individual titles; its created assets include online videos showcasing Simon & Schuster authors and new releases on YouTube, Facebook, MSN.com, SimonandSchuster.com and other sites. International publishing includes the international distribution of English-language titles through Simon & Schuster UK, Simon & Schuster Canada and Simon & Schuster Australia and other distributors, as well as the publication of local titles by Simon & Schuster UK and Simon & Schuster Australia.

        In 2010, Simon & Schuster published 154 titles that were New York Times bestsellers, including 14 New York Times #1 bestsellers. Best-selling titles in 2010 include BROKE by Glenn Beck, WOMEN FOOD AND GOD by Geneen Roth, SPOKEN FROM THE HEART by Laura Bush and FULL DARK, NO STARS by Stephen King. Bestselling children's titles from Simon & Schuster include CLOCKWORK ANGEL by Cassandra Clare, DORK DIARIES 2 by Rachel Renee Russell and CRESCENDO by Becca Fitzpatrick. Simon & Schuster Digital™, through SimonandSchuster.com, publishes original content, builds reader communities and promotes and sells Simon & Schuster's books over the Internet.

I-7

---

        The consumer publishing marketplace is subject to increased periods of demand in the summer months and during the end-of-year holiday season. Major new title releases represent a significant portion of Simon & Schuster's sales throughout the year. Simon & Schuster's top 10 accounts drive a significant portion of its annual revenue. Consumer print books are generally sold on a fully returnable basis, resulting in the return of unsold books. In the domestic and international markets, the Company is subject to global trends and local economic conditions. In 2010, the sale of digital content represented 8.0% of Simon & Schuster's revenues. The Company expects that electronic books will represent an increasing portion of Simon & Schuster revenues in the coming years.

        Publishing Competition.    The consumer publishing business is highly competitive and has been affected over the years by consolidation trends. Mass merchandisers and on-line retailers are significant factors in the industry contributing to the general trend toward consolidation in the retail channel. The growth of the electronic book market has impacted print book retailers and wholesalers and could result in a reduction of these channels for the sales and marketing of the Company's books. In addition, unfavorable economic conditions and competition may adversely affect book retailers' operations, including distribution of the Company's books. The Company must compete with other larger publishers such as Random House, Penguin Group and Harper Collins for the rights to works by authors. Competition is particularly strong for well-known authors and public personalities. In addition, technological changes have made it increasingly possible for authors to self-publish and have led to the development of new digital distribution models in which the Company's books must compete with the availability of both a larger volume of books as well as non-book content. In recent years, the Company has had to contend with price pressure on new releases, for both printed and electronic formats, as a result of price competition among book retailers. In 2010, Simon & Schuster began to enter into agency arrangements with book retailers and wholesalers in the U.S. and the U.K. under which Simon & Schuster sells its electronic books directly to the consumer and sets the consumer price. The Company still faces price competition from retailers and from competing publishers that sell directly to consumers.

        Local Broadcasting (20%, 18% and 21% of the Company's consolidated revenues in each of 2010, 2009 and 2008, respectively)

        The Local Broadcasting segment is composed of CBS Television Stations, the Company's 29 owned broadcast television stations, and CBS Radio, through which the Company owns and operates 130 radio stations in 28 U.S. markets and related online properties. In 2010, the Company launched new local Web sites in New York, Los Angeles, San Francisco and Philadelphia, among others, which combine television and radio local media brands online to provide the latest news, traffic, weather, and sports information as well as local discounts, directories and reviews to serve the local community.

        CBS Television Stations.    The Company owns 29 broadcast television stations through its CBS Television Stations group, all of which operate under licenses granted by the Federal Communications Commission ("FCC") pursuant to the Communications Act of 1934, as amended (the "Communications Act"). The licenses are renewable every eight years. The Company's television stations are located in the 8 largest, and 15 of the top 20, television markets in the U.S. The Company owns multiple television stations within the same designated market area ("DMA") in 9 major markets. These multiple station markets are: Los Angeles (market #2), Philadelphia (market #4), Dallas-Fort Worth (market #5), San Francisco-Oakland-San Jose (market #6), Boston (market #7), Detroit (market #11), Miami-Ft. Lauderdale (market #16), Sacramento-Stockton-Modesto (market #20), and Pittsburgh (market #24). This group of television stations enables the Company to reach a wide audience within and across geographically diverse markets in the U.S. The stations produce news and broadcast public affairs, sports and other programming to serve their local markets and offer CBS, The CW or MyNetworkTV programming and syndicated programming. The CBS Television Stations group principally derives its revenues from the sale of advertising time on its television stations. Substantially all of the Company's television stations operate Web sites, many of which are combined with the Web sites of the Company's radio stations in co-located markets, which promote the stations' programming, and provide news, information and entertainment, as well as other services. These Web sites principally derive revenues from the sale of advertising.

        CBS Radio.    The Company's radio broadcasting business operates through CBS Radio, one of the largest operators of radio stations in the U.S. CBS Radio owns and operates 130 radio stations serving 28 U.S. markets as of February 21, 2011. Virtually all of the Company's owned and operated radio stations are located in the 50 largest U.S. radio markets and approximately 75% in the 25 largest U.S. radio markets. The Company's strategy generally is to operate radio stations in the largest markets and take advantage of the Company's ability to sell advertising across multiple markets and formats. The Company believes that it is favorably impacted by offering radio, television and outdoor advertising platforms in large markets. The "Radio Stations, Television Stations and Outdoor Advertising Displays" table below includes information with respect to the Company's radio stations in the top 25 U.S. radio markets.

        CBS Radio's geographically dispersed stations serve diverse target demographics through a broad range of formats such as rock, classic hits/oldies, all-news, talk, Spanish language, adult contemporary, top 40/contemporary hit radio, urban, sports and country, and CBS Radio has established leading franchises in

I-10

---

news, sports and personality programming. This diversity provides advertisers with the convenience of selecting stations to reach a targeted demographic or of selecting groups of stations to reach broad groups of consumers within and across markets and also reduces the Company's dependence on any single station, local economy, format or advertiser. At the same time, CBS Radio maintains substantial diversity in each market where its stations operate so that its stations can appeal to several demographic groups. CBS Radio's general programming strategies include employing popular on-air talent, some of whose broadcasts may be syndicated by CBS Radio using the services of a third party syndicator, broadcasting programming syndicated to it by others, acquiring the rights to broadcast sports play-by-play and producing and acquiring news content for its radio stations. The overall mix of each radio station's programming lineup is designed to fit the station's specific format and serve its local community. The Company also has agreements with Westwood One, Inc. involving compensation to the Company, the provision of radio programming to CBS Radio and the distribution by Westwood One of CBS Radio News programming.

        The majority of CBS Radio's revenues are generated from the sale of local and national advertising. The major categories of radio advertisers include: automotive, retail, healthcare, telecommunications, fast food, beverage, movies and entertainment. CBS Radio is able to use the reach, diversity and branding of its radio stations to create unique division-wide marketing and promotional initiatives for major national advertisers of products and services. The success and reputation of CBS Radio and its stations allow the Company to attract the participation of major artists in these national campaigns. Advertising expenditures by local advertisers fluctuate, which has an effect on CBS Radio's revenues.

        Substantially all of the Company's radio stations operate Web sites, many of which are combined with the Web sites of the Company's television stations in co-located markets, which promote the stations' programming, and provide news, information and entertainment, as well as other services. Also, CBS Radio operates music radio station Web sites and Radio.com, which streams the broadcast of CBS Radio stations and powers custom channels for AOL Radio and Yahoo! Launchcast Radio. CBS Radio also operates Last.fm, a music discovery and social networking site, mp3.com, and TheStreetDate.com. These Web sites principally derive revenues from the sale of advertising. CBS Radio is one of the most listened to online radio providers according to Ando Media's monthly Top 20 Ranker for December 2010.

Local Broadcasting Competition.

        CBS Television Stations.    Television stations compete for programming, on-air talent, audiences and advertising revenues with other stations and cable networks in their respective coverage areas and, in some cases, with respect to programming, with other station groups, and, in the case of advertising revenues, with other local and national media. The owned and operated television stations' competitive position is largely influenced by the quality of the syndicated programs and local news programs in time periods not programmed by the network; the strength of the CBS Television Network programming and, in particular, the viewership of the CBS Television Network in the time period immediately prior to the late evening news; and in some cases, by the quality of the broadcast signal.

        CBS Radio.    The Company's radio stations directly compete within their respective markets for audience, advertising revenues and programming with other radio stations, including those owned by other group owners such as Clear Channel Communications, Citadel Broadcasting, Cumulus Media Inc., Emmis Communications, Entercom Communications Corporation and Radio One. The Company's radio stations, including its Internet and streaming activities, also compete with other media, such as broadcast, cable and DBS television, other radio stations, newspapers, magazines, direct mail, the Internet, including Internet radio services such as Pandora, Live 365 and Rhapsody. The radio industry is also subject to competition from Sirius XM Radio Inc., which provides digital audio services to subscribers.

        The Company's television and radio stations face increasing competition from newer technologies, including audio and visual programming delivered via the Internet, which create new ways for individuals to watch programming and listen to music and other content of their choosing while avoiding traditional

I-11

---

commercial advertisements. Also, an increasingly broad adoption by consumers of portable digital devices could affect the ability of the Company's television and radio stations to attract audiences and advertisers.

        Most of the Company's owned radio stations implement digital broadcasting. The Company believes that digital transmissions will provide listeners with improved sound quality and new programming channels and should facilitate the convergence of radio with other digital media. It is too early to predict the full effect that the implementation of digital broadcasts will have on the Company's radio businesses or on competition generally.

        Aggregate total revenues for the Company's radio stations for 2010 were ranked #1 in four of the top five U.S. markets by metro area population (New York, Chicago, San Francisco, and Dallas-Fort Worth), according to the 2010 Market Total Revenues Performance Summary of Miller, Kaplan, Arase & Co., LLP.

Radio Stations, Television Stations and Outdoor Advertising Displays

        The following table sets forth information with regard to the Company's radio stations, television stations and outdoor advertising displays as of February 21, 2011 in the top 25 U.S. radio markets:

I-13

I-14

---

        Outdoor (13%, 13% and 16% of the Company's consolidated revenues in 2010, 2009 and 2008, respectively)

        The Company sells, through its Outdoor businesses, advertising space on various media, including billboards, transit shelters, buses, rail systems (in-car, station platform and terminal), mall kiosks and stadium signage and in retail stores. It has outdoor advertising operations in more than 100 markets in North America, including all 50 of the largest metropolitan markets in the U.S., 19 of the 20 largest metropolitan markets in Canada and all 45 of the largest metropolitan markets in Mexico. Additionally, Outdoor has the exclusive rights to manage advertising space on approximately 90% of the total bus fleet in the U.K. and has a variety of outdoor advertising displays in the Netherlands, France, Italy, Puerto Rico, the Republic of Ireland, Spain, Argentina, Brazil, Uruguay, Chile and China. The Company operates its Outdoor businesses through CBS Outdoor in the U.S., Canada, South America and Europe, CBS Outernet® in the U.S. and Vendor® in Mexico. The "Radio Stations, Television Stations and Outdoor Advertising Displays" table above includes information with regard to the Company's outdoor advertising properties in the top 25 U.S. radio markets.

        The substantial majority of Outdoor's revenues is generated from the sale of local, regional and national advertising. Advertising rates are based on supply and demand for the particular locations, which are influenced by a particular display's exposure known as "impressions" delivered in relation to the demographics of the particular market and its location within that market. Until recently, these impressions were not measured by independent third parties. Commencing in January 2011, impressions for all fixed display such as billboards, street furniture and transit station signs are measured through the new "Eyes On" technology administered by the Traffic Audit Bureau, an independent agency formed by a number of major outdoor advertising vendors, advertising agencies and advertisers. The major categories of out-of-home advertisers include: entertainment, media, automotive, beverage, financial, real estate, retail, healthcare, telecommunications, restaurants, health and beauty aids, hotels and professional services. Out-of-home media industry advertising expenditures by retailers and the entertainment industry fluctuate, which has an effect on Outdoor's revenues.

        Outdoor generally operates in the billboard, transit, street furniture and retail store advertising markets. Outdoor primarily operates two types of billboard advertising displays, commonly referred to as "bulletins" and "posters."

        Billboard space is generally sold for periods ranging from 4 weeks to 12 months. Billboards are generally mounted on structures owned by Outdoor located on leased real property. Lease agreements are negotiated with both public and private landowners for varying terms ranging from month-to-month to year-to-year, can be for terms of 10 years or longer and may provide for renewal options. There is no significant concentration of billboards under any one lease or subject to negotiation with any one landlord.

I-15

---

        Transit advertising includes advertising on or in transit systems, including the interiors and exteriors of buses, trains and trams and at rail stations. Transit advertising contracts are negotiated with public transit authorities and private transit operators and generally provide for payment to the transit authority of a percentage of the revenues, a fixed payment, or the greater of a percentage of the revenues or a fixed payment. Where revenues are lower than anticipated, the minimum amount required to be paid to a transit authority may exceed, or be a high percentage of, the advertising revenues received by Outdoor under that advertising contract. Due to the difficult advertising marketplace worldwide, certain transit contracts, including the London Underground contract which also has reduced revenues due to project delays, are operating at their minimum guarantee levels.

        Street furniture displays, the most common of which are bus shelters, reach both vehicular and pedestrian audiences. Bus shelters are usually constructed, installed and maintained by Outdoor. Most of Outdoor's bus shelter contracts include revenue-sharing arrangements with a municipality or transit authority and often include minimum required payments. Street furniture contracts usually involve a competitive bidding process. Contracts are awarded on the basis of projected revenues to the municipality, including minimum payments, and Outdoor's willingness to construct public facilities, such as bus shelters, public toilets and information kiosks. In both its transit and street furniture negotiations, Outdoor seeks to reduce minimum payment obligations on new agreements and on renewal of existing agreements. There is no assurance that Outdoor will be successful in reducing its minimum payments, entering into new agreements or renewing certain existing agreements and any such agreements may provide a lesser return to the Company.

        Newer technologies for outdoor advertising displays, such as changeable message displays and digital billboards using light-emitting diode and liquid crystal display technology, continue to evolve. The Company keeps apprised of and has adopted such new technologies as they evolve and mature. For example, Outdoor is utilizing digital technology containing moving images in the London Underground, New York City subways and in retail outlets through CBS Outernet. CBS Outernet, a leading distributor of video programming and advertising content to retail stores, enables customized messaging by region and retail environment. Generally, CBS Outernet enters into revenue-sharing arrangements with retailers based on advertising sales.

        Outdoor's business strategy involves expanding its presence in major selected markets, to grow its revenues and cash flow by being a leading provider of out-of-home advertising services in the markets it serves, controlling costs, developing and entering into new markets and using advanced technologies to build greater awareness and promote tactical advertising. In addition, the Company purchases outdoor advertising assets within its existing markets or in contiguous markets. The Company believes that there will be continuing opportunities for implementing its acquisition and development strategies given the outdoor advertising industry's fragmentation. This is particularly true in the international markets where there are opportunities for Outdoor to increase profitability both from acquiring additional assets in or near its existing operations and from future acquisitions in new markets.

        Outdoor Competition.    The outdoor advertising industry is fragmented, consisting of several large companies involved in outdoor advertising such as Clear Channel Outdoor Holdings, Inc., JCDecaux S.A., Cemusa Inc., Titan Outdoor Holdings, Inc. and Lamar Advertising Company as well as hundreds of smaller regional and local companies operating a limited number of display faces in a single or a few local markets. The Company also competes with other media, including broadcast and cable television, radio, print media, the Internet and direct mail marketers, within their respective markets. In addition, it competes with a wide variety of out-of-home media, including advertising in shopping centers, airports, movie theaters, supermarkets and taxis. Advertisers compare relative costs of available media and cost-per-thousand impressions, particularly when delivering a message to customers with distinct demographic characteristics. In competing with other media, the outdoor advertising industry relies on its relative cost efficiency and its ability to reach a broad segment in a specific market or to target a particular geographic area or population with a particular demographic within that market. The Company keeps

I-16

---

apprised of the evolution of new technologies in the industry. As new technologies such as digital billboards prove desirable to Outdoor's customers and deliver appropriate returns on investment, the Company's costs could increase.

        The Company believes that its strong emphasis in sales and customer service and its position as a leading provider of advertising services in each of its primary markets as well as its international inventory enables it to compete effectively with the other outdoor advertising companies, as well as other media, within those markets.

REGULATION

        The Company's businesses are either subject to or affected by regulations of federal, state and local governmental authorities. The rules, regulations, policies and procedures affecting these businesses are subject to change. The descriptions which follow are summaries and should be read in conjunction with the texts of the statutes, rules and regulations described herein. The descriptions do not purport to describe all present and proposed statutes, rules and regulations affecting the Company's businesses.

Intellectual Property and Privacy

        Laws affecting intellectual property are of significant importance to the Company. (See "Intellectual Property" on page I-22).

        Unauthorized Distribution of Copyrighted Content and Piracy.    Unauthorized distribution, reproduction or display of copyrighted material over the Internet and through physical devices without regard to content owners' copyright rights in television programming, motion pictures, clips and books, such as through pirated DVDs, user-generated content, streaming, Internet downloads, file "sharing" and peer-to-peer services, is a threat to copyright owners' ability to protect and exploit their property. The Company is engaged in enforcement and other activities to protect its intellectual property and has participated in various litigations and public relations programs and legislative activity. In addition to these efforts, the Company continues to enter into and explore possibilities for commercial arrangements with various online providers to further protect and exploit its content.

        Copyright Law and Content.    In the U.S., the copyright term for authored works is the life of the author plus 70 years. For works made for hire, the copyright term is the shorter of 95 years from the first publication or 120 years from creation.

        Privacy.    The laws and regulations governing the collection, use and transfer of consumer information are complex and rapidly evolving, particularly as they relate to the Company's interactive businesses. The Company monitors and considers these laws and regulations in the design and operation of its legal and regulatory compliance programs.

Broadcasting

        General.    Television and radio broadcasting are subject to the jurisdiction of the FCC pursuant to the Communications Act. The Communications Act empowers the FCC, among other actions, to issue, renew, revoke and modify broadcasting licenses; determine stations' frequencies, locations and operating power; regulate some of the equipment used by stations; adopt other regulations to carry out the provisions of the Communications Act and other laws, including requirements affecting the content of broadcasts; and to impose penalties for violation of its regulations, including monetary forfeitures, short-term renewal of licenses and, in egregious cases, license revocation or denial of license renewals.

        Under the Communications Act, the FCC also regulates certain aspects of the operation of cable and DBS systems and certain other electronic media that compete with broadcast stations.

I-17

---

        Indecency and Profanity Regulation.    The FCC's rules prohibit the broadcast of obscene material at any time and indecent or profane material between the hours of 6 a.m. and 10 p.m. Broadcasters risk violating the prohibition against broadcasting indecent or profane material because the vagueness of the FCC's indecency/profanity definition makes it difficult to apply, particularly with respect to spontaneous, live programming. The FCC's maximum forfeiture penalty for broadcasting indecent or profane programming is $325,000 per indecent or profane utterance with a maximum forfeiture exposure of $3.0 million for any continuing violation arising from a single act or failure to act. The Company is and has been involved in litigation and, from time to time, has received and may receive in the future letters of inquiry from the FCC prompted by complaints alleging that certain programming on its broadcast stations included indecent or profane material. (See Item 7. "Management's Discussion and Analysis of Results of Operations and Financial Condition—Legal Matters—Indecency Regulation" on page II-35).

        License Renewals.    Radio and television broadcast licenses are typically granted for standard terms of eight years. The Communications Act requires the FCC to renew a broadcast license if the FCC finds that the station has served the public interest, convenience and necessity and, with respect to the station, there have been no serious violations by the licensee of either the Communications Act or the FCC's rules and regulations and there have been no other violations by the licensee of the Communications Act or the FCC's rules and regulations that, taken together, constitute a pattern of abuse. The Company has a number of pending renewal applications, nine of which have been opposed by third parties (there are two opposed renewal applications for Radio and seven opposed renewal applications for Television Stations).

        License Assignments.    The Communications Act requires prior FCC approval for the assignment of a license or transfer of control of an FCC licensee. Third parties may oppose the Company's applications to transfer or acquire additional broadcast licenses.

        Ownership Regulation.    The Communications Act and FCC rules and regulations limit the ability of individuals and entities to have an official position or ownership interest, known as an "attributable" interest, above specific levels in broadcast stations as well as in other specified mass media entities. In seeking FCC approval for the acquisition of a broadcast radio or television station license, the acquiring person or entity must demonstrate that the acquisition complies with the FCC's ownership rules or that a waiver of the rules is in the public interest. In December 2007, the FCC concluded a proceeding which examined whether to modify its various ownership rules, but with the exception of the newspaper-broadcast cross-ownership rule, the FCC declined to do so. The FCC's action was appealed to the United States Court of Appeals for the Third Circuit by the Company and other interested parties. Oral argument in this case took place in February 2011.

        The FCC's ownership rules are briefly summarized below.

        Local Radio Ownership.    The FCC's local radio ownership rule applies in all markets where the Company owns radio stations. Under that rule, one party may own up to eight radio stations in the largest markets, no more than five of which may be either AM or FM. With a few exceptions, the rule permits the common ownership of 8 radio stations in the top 50 markets, where CBS Radio has significant holdings. The Company's FM radio portfolio exceeds the FCC's numerical limit in one market, West Palm Beach, which is grandfathered. While the rules do not require the divestiture of any existing radio ownership combinations, the Company is not permitted to transfer its radio portfolio in that market intact, except to qualified small businesses.

        Local Television Ownership.    Under the FCC's local television ownership rule, one party may own up to two television stations in the same DMA, so long as at least one of the two stations is not among the top four-ranked stations in the market based on audience share as of the date an application for approval of an acquisition is filed with the FCC, and at least eight independently owned and operating full-power television stations remain in the market following the acquisition. Further, without regard to the number of remaining independently owned

I-18

---

television stations, the rule permits the ownership of more than one television station within the same DMA so long as certain signal contours of the stations involved do not overlap. Satellite television stations that simply rebroadcast the programming of a "parent" television station are exempt from the local television ownership rule if located in the same DMA as the "parent" station.

        Television National Audience Reach Limitation.    Under the FCC's national television ownership rule, one party may not own television stations which reach more than 39% of all U.S. television households. For purposes of calculating the total number of television households reached by a station, the FCC attributes a UHF television station with only 50% of the television households in its market. The Company currently owns and operates television stations that reach approximately 38% of all U.S. television households but for purposes of the national ownership limitation, the Company's reach is less than this amount applying the UHF discount in accordance with the FCC's methodology.

        Radio-Television Cross-Ownership Rule.    The radio-television cross-ownership rule limits the common ownership of radio and television stations in the same market. The numeric limit varies according to the number of independent media voices in the market. The Company owns a combination of radio and television stations in the Los Angeles market in excess of the limit. The FCC granted an application permitting the Company to assign radio station KFWB-AM in Los Angeles to a divestiture trust, the closing of which would bring the Company into compliance with the rule. A petition for reconsideration of this grant has been filed with the FCC, which remains pending, and the closing of this assignment has been delayed.

        Newspaper-Broadcast Cross-Ownership.    The newspaper-broadcast cross-ownership rule prohibits the common ownership of a broadcast station and daily newspaper in the same market. The FCC modified the newspaper-broadcast cross-ownership rule by establishing a presumption in favor of permitting cross-ownership of a daily newspaper and one broadcast station (but not one of the "top four" television stations) in the top 20 markets under certain circumstances and establishing a waiver procedure for such combinations in smaller markets. However, the United States Court of Appeals for the Third Circuit has stayed the effectiveness of this rule change. The rule in effect continues to prohibit the cross-ownership of daily newspapers and broadcast stations in all markets absent a waiver by the FCC.

        Dual Network Rule.    The dual network rule prohibits any of the four major networks, ABC, CBS, FOX and NBC, from combining.

        Attribution of Ownership.    Under the FCC's attribution rules, a direct or indirect purchaser of various types of securities of an entity which holds FCC licenses, such as the Company, could violate the foregoing FCC ownership regulations or policies if that purchaser owned or acquired an "attributable" interest in other media properties. Under the FCC's rules, an "attributable" interest for purposes of the FCC's broadcast ownership rules generally includes: equity and debt interests which combined exceed 33% of a licensee's total assets, if the interest holder supplies more than 15% of the licensee's total weekly programming, or has an attributable same-market media interest, whether television, radio, cable or newspaper; a 5% or greater direct or indirect voting stock interest, including certain interests held in trust, unless the holder is a qualified passive investor in which case the threshold is a 20% or greater voting stock interest; any equity interest in a limited liability company or a partnership, including a limited partnership, unless properly "insulated" from management activities; and any position as an officer or director of a licensee or of its direct or indirect parent. The FCC is currently reviewing its single majority voting shareholder attribution exemption, which renders as non-attributable voting interests up to 49% in a licensee controlled by a single majority voting shareholder. Because NAI holds an attributable interest in both the Company and Viacom Inc., the business of each company is

I-19

---

attributable to the other for certain FCC purposes, which may have the effect of limiting and affecting the activities, strategic business alternatives and business terms available to the Company. (See Item 1A. "Risk Factors—The Businesses of the Company and Viacom Inc. Will Be Attributable to the Other Company for Certain Regulatory Purposes").

        Alien Ownership.    In general, the Communications Act prohibits foreign individuals or entities from owning more than 20% of the voting power or equity of the Company.

        Cable and Satellite Carriage of Television Broadcast Stations.    The 1992 Cable Act and implementing FCC regulations govern the retransmission of commercial television stations by cable television operators. Every three years, a television station must elect, with respect to cable systems within its DMA, either "must carry" status, pursuant to which the cable system's carriage of the station is mandatory, or "retransmission consent," pursuant to which the station gives up its right to mandatory carriage and secures instead the right to negotiate consideration in return for consenting to carriage. The Company has elected the retransmission consent option in substantially all cases for the period beginning January 1, 2009, and, since 2006, has implemented a systematic process of seeking monetary consideration for its retransmission consent.

        Similarly, federal legislation and FCC rules govern the retransmission of broadcast television stations by DBS operators. DBS operators are required to carry the signals of all local television broadcast stations requesting carriage in local markets in which the DBS operator carries at least one signal pursuant to the statutory local-to-local compulsory copyright license. Every three years, each television station in such markets must elect "must carry" or "retransmission consent" status, in a manner similar to that described above with respect to cable systems. Substantially all of the Company's owned and operated television stations are being transmitted into their local markets by the two major DBS operators pursuant to retransmission consent agreements.

        Children's Television Programming.    Federal legislation and FCC rules limit the amount and content of commercial matter that may be shown on television stations during programming designed for children 12 years of age and younger, and require stations to broadcast on their main program stream three hours per week of educational and informational programming ("E/I programming") designed for children 16 years of age and younger. FCC rules also impose E/I programming requirements on each additional digital multicast program stream transmitted by television stations, with the requirement increasing in proportion to the additional hours of free programming offered on multicast channels. These rules also limit the display during children's programming of Internet addresses of Web sites that contain or link to commercial material or that use program characters to sell products.

        Program Access.    Under the Communications Act, vertically integrated cable programmers (more fully described below) are generally prohibited from offering different prices, terms or conditions to competing multichannel video programming distributors unless the differential is justified by certain permissible factors set forth in the FCC's regulations. The FCC's "program access" rules also limit the ability of a vertically integrated cable programmer to enter into exclusive distribution arrangements with cable operators. A cable programmer is considered to be vertically integrated under the FCC's program access attribution rules if it owns or is owned by a cable operator in whole or in part. Cable operators for this purpose may include telephone companies that provide video programming directly to subscribers.

        The Company's wholly owned program services are not currently subject to the program access rules. The Company's flexibility to negotiate the most favorable terms available for carriage of these services and its ability to offer cable operators exclusive programming could be adversely affected if it were to become subject to the program access rules. Because the Company and Viacom Inc. are under common control by NAI, Viacom Inc.'s businesses could be attributable to the Company for purposes of the FCC's program access rules. (See Item 1A. "Risk Factors—The Businesses of the Company and Viacom Inc. Will Be Attributable to the Other Company for Certain Regulatory Purposes").

I-20

---

        Digital Radio.    For a number of years, the FCC has been developing rules that would permit existing AM and FM radio broadcast stations to broadcast digitally in order both to improve sound quality and to provide spectrum for enhanced data services to complement the existing programming service and provide new business opportunities for radio broadcasters, including multicasting opportunities. The FCC has authorized AM and FM radio stations to broadcast digital signals using excess spectrum within the same allotted bandwidth used for analog transmissions. In 2010, the FCC increased the maximum allowable power for digital broadcasts, which will improve the robustness and geographic coverage of digital transmissions. As of February 1, 2011, 107 of the Company's radio stations had commenced digital broadcasts.

Outdoor

        The outdoor advertising industry is subject to extensive governmental regulation at the federal, state and local levels in the U.S. and to national, regional and local restrictions in foreign countries. These regulations can affect the operation of advertising displays and include restrictions on the construction, repair, upgrading, height, size and location of outdoor advertising structures and, in some instances, the content of advertising copy that can be displayed on these structures. In addition, outdoor advertising is the subject of targeted state and municipal taxes and fees. These laws may affect competitive conditions in various markets in various ways. Such laws may reduce the Company's expansion opportunities, or may increase or reduce competitive pressure from others. No assurance can be given that existing or future laws or regulations and the enforcement thereof will not materially and adversely affect the Outdoor business.

        Under U.S. law, principally the Highway Beautification Act of 1965 (the "HBA"), outdoor advertising is controlled on primary and interstate highways built with federal financial assistance. As a condition to federal highway assistance, the HBA requires states to restrict billboards on such highways to commercial and industrial areas, and imposes certain additional size, spacing and other requirements associated with the installation and operation of billboards. Outdoor is not aware of any states which have passed laws and adopted regulations which are less restrictive than the federal requirements, including the obligation on the part of the billboard owner to remove, at the owner's expense and without compensation, any non-grandfathered signs on such highways that do not comply with such requirements. Outdoor does not believe that the number of its billboards that may be subject to removal under these regulations is material. No state in which Outdoor operates has banned billboards, but some have adopted standards more restrictive than the federal requirements. Municipal and county governments generally also have sign controls as part of their zoning laws and building codes. Some state and local governments prohibit construction of new billboards and some allow new construction only to replace existing structures, although most allow construction of billboards subject to restrictions on zoning, size, spacing, height and type of construction. In some cases, the construction of new billboards or the relocation or modification of existing billboards is prohibited. A number of cities including New York City, Los Angeles, Philadelphia and Miami have implemented or initiated legislative billboard controls, including imposing taxes, fees and/or registration requirements in an effort to decrease or restrict the number of outdoor signs and/or to raise revenue. The Company contests such laws and regulations that it believes unlawfully restrict its constitutional or other legal rights and may adversely impact the growth of its outdoor advertising business.

        U.S. law neither requires nor prohibits removal of existing lawful billboards, but it does require payment of compensation if a state or political subdivision compels the removal of a lawful billboard along a primary or interstate highway that was built with federal financial assistance. State governments have purchased and removed legal billboards for beautification objectives in the past using federal funding for transportation enhancement programs, and may do so in the future. State government authorities from time to time use the power of eminent domain to remove billboards. Thus far, Outdoor has been able to obtain satisfactory compensation for its billboards purchased or removed as a result of this type of governmental action, although there is no assurance that this will continue to be the case in the future. Local governments do not generally purchase billboards for beautification, but some have attempted to

I-21

---

force removal of legal but nonconforming billboards (billboards which conformed with applicable zoning regulations when built but which do not conform to current zoning regulations) after a period of years under a concept called amortization. Under this concept the governmental body asserts that just compensation is earned by continued operation of the billboard over time. Although there is some question as to the legality of amortization under federal and many state laws, amortization has been upheld in some instances. Outdoor generally has been successful in negotiating settlements with municipalities for billboards required to be removed. Restrictive regulations also limit Outdoor's ability to rebuild or replace nonconforming billboards.

        As the owner or operator of various real properties and facilities in outdoor advertising operations, the Company must comply with various U.S. federal, state and local and foreign environmental, health, safety and land use laws and regulations. The Company and its properties are subject to such laws and regulations relating to the use, storage, disposal, emission and release of hazardous and non-hazardous substances and employee health and safety, as well as zoning and other land use restrictions which may affect, among other things, the hours of operation and illumination as well as methods and conditions of maintenance of facilities and advertising installation. Historically, the Company has not incurred significant expenditures to comply with these laws. However, future laws or a finding of a violation of or liability under existing laws could require the Company to make significant expenditures and otherwise limit or restrict its ability to use or operate some of its displays.

        Certain products, services and types of displays are or may be targeted by federal, state and local laws and regulations. For example, out-of-court settlements between the major U.S. tobacco companies, the U.S. government, and all 50 states as well as regulations promulgated by the U.S. Food and Drug Administration agency provide for a ban on the outdoor advertising of tobacco products. In addition, state and local governments continue to initiate proposals designed to limit outdoor advertising of alcohol. Legislation regulating alcohol-related advertising due to content-related restrictions could cause a reduction in Outdoor's direct revenue from such advertisements and a simultaneous increase in the available space on the existing inventory of billboards in the outdoor advertising industry.

Financial Condition" and the consolidated financial statements and related notes in "Item 8. Financial Statements and Supplementary Data" of this Form 10-K.

A Decline in Advertising Expenditures Could Cause the Company's Revenues and Operating Results to Decline Significantly in Any Given Period or in Specific Markets

        The Company derives substantial revenues from the sale of advertising on its broadcast and basic cable networks, television stations, radio stations, outdoor media and syndicated programming. A decline in the economic prospects of advertisers, the economy in general or the economy of any individual geographic market, particularly a major market such as Los Angeles, New York or Chicago, in which the Company owns and operates sizeable businesses, could alter current or prospective advertisers' spending priorities. Disasters, acts of terrorism, political uncertainty or hostilities could lead to a reduction in advertising expenditures as a result of uninterrupted news coverage and economic uncertainty. Advertising expenditures may also be affected by increasing competition for the leisure time of audiences. In addition, advertising expenditures by companies in certain sectors of the economy, including the automotive, financial and pharmaceutical segments, represent a significant portion of the Company's advertising revenues. Any political, economic, social or technological change resulting in a reduction in these sectors' advertising expenditures may adversely affect the Company's revenue. Advertisers' willingness to purchase advertising from the Company may also be affected by a decline in audience ratings for the Company's programming, the inability of the Company to retain the rights to popular programming, increasing audience fragmentation caused by the proliferation of new media formats, including cable networks, the Internet and video-on-demand and the deployment of portable digital devices and new technologies which allow consumers to time shift programming, make and store digital copies and skip or fast-forward through advertisements. The Company's revenues from outdoor advertising also depend on the Company's continued ability to obtain the right to use effective outdoor advertising space. Any reduction in advertising expenditures could have an adverse effect on the Company's revenues and results of operations.

The Company's Success Is Dependent Upon Audience Acceptance of Its Content, Including Its Television and Radio Programs and Motion Pictures, Which Is Difficult to Predict

        Television, radio and motion picture content production and distribution are inherently risky businesses because the revenues derived from the production and distribution of a television or radio program or motion picture, and the licensing of rights to the associated intellectual property, depend primarily upon their acceptance by the public, which is difficult to predict. The commercial success of a television or radio program or motion picture also depends upon the quality and acceptance of other competing programs and motion pictures released into the marketplace at or near the same time, the availability of alternative forms of entertainment and leisure time activities, general economic conditions and other tangible and intangible factors, all of which are difficult to predict. Rating points are also factors that are weighed when determining the advertising rates that the Company receives. The use of new ratings technologies and measurements could have an impact on the Company's program ratings. Poor ratings can lead to a reduction in pricing and advertising spending. For example, there can be no assurance that any replacement programming on the Company's radio or television stations will generate the same level of revenues or profitability of previous programming. In addition, the success of the Company's cable networks and Simon & Schuster is similarly dependent on audience acceptance of its programming and publications, respectively. The theatrical success of a motion picture, based in large part upon audience acceptance, is a significant factor in determining the revenues it is likely to generate in home entertainment sales, licensing fees and other exploitation during the various other distribution windows. Consequently, low public acceptance of the Company's content, including its television and radio programs, motion pictures and publications, will have an adverse effect on the Company's results of operations.

Failure by the Company to Obtain, Create and Retain the Rights in Popular Programming Could Adversely Affect the Company's Revenues

        Operating results from the Company's programming (including motion pictures) businesses fluctuate primarily with the acceptance of such programming by the public, which is difficult to predict. The Company's revenue from its television, radio, cable networks and motion picture business is therefore partially dependent on the Company's continued ability to anticipate and adapt to changes in consumer tastes and behavior on a timely basis. Moreover, the Company derives a portion of its revenues from the exploitation of its extensive library of television programming. Generally, a television series must have a network run of at least three or four years to be successfully sold in domestic syndication. If the content of its television programming library ceases to be widely accepted by audiences or is not continuously replenished with popular content, the Company's revenues could be adversely affected. The Company obtains a significant portion of its popular programming from third parties. For example, some of CBS Television Network's most widely viewed broadcasts, including the NCAA's Men's Final Four, golf's Masters Tournament and PGA Championship, and NFL games, are made available based upon programming rights of varying duration that the Company has negotiated with third parties. In addition, Showtime Networks enters into commitments to acquire rights to certain programming for Showtime, The Movie Channel and Flix from motion picture producers and other suppliers for varying durations, and CBS Radio acquires the broadcast rights to syndicated shows and to various programs, such as sports events from third parties. CBS Films competes for compelling source material for and the talent necessary to produce motion pictures. Competition for popular programming that is licensed from third parties is intense, and the Company may be outbid by its competitors for the rights to new, popular programming or in connection with the renewal of popular programming currently licensed by the Company. The Company's failure to obtain or retain rights to popular content could adversely affect the Company's revenues.

Any Decrease in Popularity of the Programming for Which the Company Has Incurred Significant Commitments Could Have an Adverse Effect on Its Profitability

        Programming and talent commitments of the Company, estimated to aggregate approximately $7.99 billion as of December 31, 2010, primarily included $3.92 billion for sports programming rights, $3.29 billion relating to television, radio, film production and licensing and $777.1 million for talent contracts, with $1.33 billion of these amounts payable in and after 2016. A shortfall, now or in the future, in the expected popularity of the sports events for which the Company has acquired rights, or in the television and radio programming the Company expects to distribute, could lead to decreased profitability or losses for a significant period of time.

The Company Must Respond to Rapid Changes in Technology, Content Creation, Services and Standards in Order to Remain Competitive

        Video, telecommunications, radio and data services technologies used in the entertainment industry are changing rapidly as are the digital distribution models for books. Advances in technologies or alternative methods of product delivery or storage, or certain changes in consumer behavior driven by these or other technologies and methods of delivery and storage, could have a negative effect on the Company's businesses. Examples of the foregoing include the convergence of television broadcasts and online delivery of programming to televisions, video-on-demand, satellite radio, new video and electronic book formats, user-generated content sites, Internet and mobile distribution of video content via streaming and downloading, and digital outdoor displays. For example, devices that allow users to view or listen to television or radio programs on a time-delayed basis and technologies that enable users to fast-forward or skip advertisements, such as DVRs and portable digital devices and systems that enable users to store programming, may cause changes in consumer behavior that could affect the attractiveness of the Company's offerings to advertisers and could therefore adversely affect its revenues. Also, the growing

I-25

---

uses of user-generated content sites and live and stored video streaming sites, which house unauthorized copies of copyrighted content, including those emanating from other countries in various languages, may adversely impact the Company's businesses. In addition, further increases in the use of digital devices which allow users to view or listen to content of their own choosing, in their own time and remote locations, while avoiding traditional commercial advertisements or subscription payments, could adversely affect the Company's radio and television broadcasting advertising and subscription revenues. Cable providers and DBS operators are developing new techniques that allow them to transmit more channels on their existing equipment to highly targeted audiences, reducing the cost of creating channels and potentially leading to the division of the television marketplace into more specialized niche audiences. More television options increase competition for viewers and competitors targeting programming to narrowly defined audiences may gain an advantage over the Company for television advertising and subscription revenues. Television manufacturers, cable providers and others are developing and offering technology to enable viewers to locate digital copies of programming from the Internet to view on television monitors, which could diminish viewership of the Company's programming. Generally, changing consumer behavior may impact the Company's traditional distribution methods, for example, by reducing viewership of its programming (including motion pictures), the demand for DVD product and/or the desire to see motion pictures in theaters, which could have an adverse impact on the Company's revenues and profitability. The ability to anticipate and adapt to changes in technology on a timely basis and exploit new sources of revenue from these changes will affect the Company's ability to continue to grow and increase its revenue.

Piracy of the Company's Programming and Other Content, Including Digital and Internet Piracy, May Decrease Revenue Received from the Exploitation of the Company's Programming and Other Content and Adversely Affect Its Businesses and Profitability

        Piracy of programming (including motion pictures), books and other copyrighted material is prevalent in many parts of the world and is made easier by the availability of digital copies of content and technological advances allowing conversion of such programming and other content into digital formats, which facilitate the creation, transmission and sharing of high quality unauthorized copies of the Company's content. Recent technological advances, which facilitate the streaming of programming via the Internet to television screens, may increase piracy. The proliferation of unauthorized copies and piracy of programming has an adverse effect on the Company's businesses and profitability because these unauthorized actions reduce the revenue that the Company potentially could receive from the legitimate sale and distribution of its products and services. In addition, if piracy were to increase, it would have an adverse effect on the Company's businesses and profitability. Also, while legal protections exist, piracy and technological tools with which to carry it out continue to escalate and present challenges for enforcement. Failure of legal protections to evolve and enable enhanced enforcement efforts to combat piracy could make it more difficult for the Company to adequately protect its intellectual property, which could negatively impact its value and further increase the Company's enforcement costs.

The Company's Operating Results Are Subject to Seasonal Variations and Other Factors

        The Company's business has experienced and is expected to continue to experience seasonality due to, among other things, seasonal advertising patterns and seasonal influences on people's viewing, reading, attendance and listening habits. Typically, the Company's revenue from advertising increases in the fourth quarter, Simon & Schuster generates a substantial portion of its revenues in the fourth quarter, and CBS Films' revenue from motion pictures is dependent on the timing, mix, number and availability of its pictures. In addition, advertising revenues in even-numbered years benefit from advertising placed by candidates for political offices. The effects of such seasonality make it difficult to estimate future operating results based on the previous results of any specific quarter and may adversely affect operating results.

I-26

The Company's Businesses Operate in Highly Competitive Industries

        The Company competes with other media companies for high quality content and attractive outdoor advertising space to achieve large audiences and to generate advertising revenue. The Company also competes for distribution on various cable, DBS and other platforms. The Company's ability to attract audiences and advertisers and obtain favorable distribution depends in part on its ability to provide popular television programming and radio programming, motion pictures and books, as well as well-placed outdoor advertising faces. In addition, the consolidation of advertising agencies, distributors and television service providers has made competition for audiences, advertising revenue, and distribution more intense. In addition, consolidation among book retailers and the growth of on-line sales and electronic books sales have resulted in increased competition for limited physical shelf space for the Company's publications and for the attention of consumers on-line. Competition for audiences and advertising comes from: broadcast television stations and networks; cable television systems and networks; motion picture studios; the Internet; terrestrial and satellite radio and portable devices; outdoor advertisers; local, regional and national newspapers; direct mail; and other communications and advertising media that operate in these markets. Other television and radio stations or cable networks may change their formats or programming, a new station or new network may adopt a format to compete directly with the Company's stations or networks, or stations or networks might engage in aggressive promotional campaigns. In book publishing, price competition among electronic and print book retailers could decrease the prices for new releases and the outlets available for book sales. This competition could result in lower ratings and advertising and subscription and other revenues or increased promotional and other expenses and, consequently, lower earnings and cash flow for the Company. The Company cannot be assured that it will be able to compete successfully in the future against existing or potential competitors, or that competition will not have a material adverse effect on its business, financial condition or results of operations.

Economic Conditions May Adversely Affect the Company's Businesses and Customers

        The U.S. and other countries where the Company operates have experienced slowdowns and volatilities in their economies. A downturn could lead to lower consumer and business spending for the Company's products and services, particularly if customers, including advertisers, subscribers, licensees, retailers, theater operators and other consumers of the Company's content offerings and services, reduce demands for the Company's products and services. In addition, in unfavorable economic environments, the Company's customers may have difficulties obtaining capital at adequate or historical levels to finance their ongoing business and operations and may face insolvency, all of which could impair their ability to make timely payments and continue operations, including distribution of the Company's content. The Company is unable to predict the duration and severity of weakened economic conditions and such conditions and resultant effects could adversely impact the Company's businesses, operating results, and financial condition.

Volatility and Weakness in Capital Markets May Adversely Affect Credit Availability and Related Financing Costs for the Company

        Bank and capital markets can experience periods of volatility and disruption. If the disruption in these markets is prolonged, the Company's ability to refinance, and the related cost of refinancing, some or all of its debt could be adversely affected. Although the Company can currently access the bank and capital markets, there is no assurance that such markets will continue to be a reliable source of financing for the Company. In addition, the Company's access to and cost of borrowing can be affected by the Company's short- and long-term debt ratings assigned by ratings agencies. These factors, including the tightening of credit markets, or a decrease in the Company's debt ratings, could adversely affect the Company's ability to obtain cost-effective financing.

I-27

Increased Programming and Content Costs May Adversely Affect the Company's Profits

        The Company produces and acquires programming (including motion pictures) and content and incurs costs for all types of creative talent, including actors, authors, writers and producers as well as marketing and distribution. An increase in any of these costs may lead to decreased profitability.

Changes in U.S. Communications Laws or Other Regulations May Have an Adverse Effect on the Company's Business

        The television and radio broadcasting and distribution industries in the U.S. are highly regulated by U.S. federal laws and regulations issued and administered by various federal agencies, including the FCC. The television and radio broadcasting industry is subject to extensive regulation by the FCC under the Communications Act. For example, the Company is required to obtain licenses from the FCC to operate its radio and television stations. The Company cannot be assured that the FCC will approve its future renewal applications or that the renewals will be for full terms or will not include conditions or qualifications. The non-renewal, or renewal with substantial conditions or modifications, of one or more of the Company's licenses could have a material adverse effect on the Company's revenues. The Company must also comply with extensive FCC regulations and policies in the ownership and operation of its television and radio stations and its television networks. FCC regulations prohibit the ownership of more than one of the top four networks, ABC, CBS, FOX and NBC, and limit the number of television and radio stations that a licensee can own in a market and the number of television stations that can be owned nationwide, which could restrict the Company's ability to consummate future transactions and in certain circumstances could require it to divest some television or radio stations. The U.S. Congress and the FCC currently have under consideration, and may in the future adopt, new laws, regulations, and policies regarding a wide variety of matters that could, directly or indirectly, affect the operation and ownership of the Company's radio and television properties. For example, from time to time, proposals have been advanced in the U.S. Congress and at the FCC to require radio and television broadcast stations to provide advertising time to political candidates for free or at a reduced charge. Any restrictions on political advertising may adversely affect the Company's advertising revenues. The FCC has initiated a proceeding to examine and potentially regulate more closely embedded advertising such as product placement and product integration. Enhanced restrictions affecting these means of delivering advertising messages may adversely affect the Company's advertising revenues. Changes to the media ownership and other FCC rules may affect the competitive landscape in ways that could increase the competition faced by the Company. Proposals have also been advanced from time to time before the U.S. Congress and the FCC to extend the program access rules (currently applicable only to those cable program services which also own or are owned by cable distribution systems) to all cable program services. The Company's ability to obtain the most favorable terms available for its content could be adversely affected should such an extension be enacted into law. Legislation could be enacted, which could remove over-the-air broadcasters' existing exemption from payment of a performance royalty to record companies and performers of music which is broadcast on radio stations and could have an adverse impact on the cost of music programming for the Company. In addition, changes in international laws and regulations governing the Internet may have an adverse impact on the Company's international businesses and Internet properties. The Company is unable to predict the effect that any such laws, regulations or policies may have on its operations.

Vigorous Enforcement or Enhancement of FCC Indecency and Other Program Content Rules Against the Broadcast and Cable Industries Could Have an Adverse Effect on the Company's Businesses and Results of Operations

        The FCC's rules prohibit the broadcast of obscene material at any time and indecent or profane material on television or radio broadcast stations between the hours of 6 a.m. and 10 p.m. Broadcasters risk violating the prohibition against broadcasting indecent material because of the vagueness of the FCC's indecency/profanity definition, coupled with the spontaneity of live programming. The FCC vigorously

I-28

---

enforces its indecency rules against the broadcasting industry. The FCC has found on a number of occasions that the content of radio and television broadcasts has contained indecent material. In such instances, the FCC issued fines or advisory warnings to the offending licensees. Moreover, the FCC has in some instances imposed separate fines for each allegedly indecent "utterance," in contrast with its previous policy, which generally considered all indecent words or phrases within a given program as constituting a single violation. The fines for broadcasting indecent material are a maximum of $325,000 per utterance. If the FCC denied a license renewal or revoked the license for one of the Company's broadcast radio or television stations, the Company would lose its authority to operate the station. The determination of whether content is indecent is inherently subjective and, as such, it can be difficult to predict whether particular content could violate indecency standards. The difficulty in predicting whether individual programs, words or phrases may violate the FCC's indecency rules adds significant uncertainty to the Company's ability to comply with the rules. Violation of the indecency rules could lead to sanctions which may adversely affect the Company's businesses and results of operations. Some policymakers support the extension of the indecency rules that are applicable to over-the-air broadcasters to cover cable and satellite programming and/or attempts to increase enforcement of or otherwise expand existing laws and rules. If such an extension, attempt to increase enforcement or other expansion took place and were found to be constitutional, some of the Company's cable content could be subject to additional regulation and might not be able to attract the same subscription and viewership levels.

The Loss of Affiliation Agreements or Retransmission Agreements Could Materially Adversely Affect the Company's Results of Operations

        The CBS Television Network provides its affiliates with up to approximately 98 hours of regularly scheduled programming per week. In return, the CBS Television Network's affiliated stations broadcast network-inserted commercials during that programming. Loss of network affiliation agreements of the CBS Television Network could adversely affect the Company's results of operations by reducing the reach of the Company's programming and therefore its attractiveness to advertisers, and renewal of these affiliation agreements on less favorable terms may also adversely affect the Company's results of operations. The non-renewal or termination of retransmission agreements with cable, DBS and other distributors or continued distribution on less favorable terms, could also adversely affect the Company's ability to distribute its network programming to a nationwide audience and affect the Company's ability to sell advertising, which could have a material adverse effect on the Company's results of operations. Showtime Networks and the CBS College Sports Network are also dependent upon the maintenance of affiliation agreements with cable, DBS and other distributors, and there can be no assurance that these agreements will be renewed in the future on terms acceptable to such programmers. The loss of one or more of these arrangements could reduce the distribution of Showtime Networks' and CBS College Sports Network's program services and reduce revenues from subscriber fees and advertising, as applicable. Further, the loss of favorable packaging, positioning, pricing or other marketing opportunities with any distributor could reduce revenues from subscriber fees. In addition, consolidation among cable and DBS distributors and increased vertical integration of such distributors into the cable or broadcast network business have provided more leverage to these distributors and could adversely affect the Company's ability to maintain or obtain distribution for its network programming or distribution and/or marketing of its subscription program services on favorable or commercially reasonable terms, or at all.

The Failure or Destruction of Satellites and Transmitter Facilities that the Company Depends Upon to Distribute Its Programming Could Materially Adversely Affect the Company's Businesses and Results of Operations

        The Company uses satellite systems to transmit its broadcast and cable networks to affiliates. The distribution facilities include uplinks, communications satellites and downlinks. Transmissions may be disrupted as a result of local disasters including extreme weather that impair on-ground uplinks or downlinks, or as a result of an impairment of a satellite. Currently, there are a limited number of

I-29

---

communications satellites available for the transmission of programming. If a disruption occurs, the Company may not be able to secure alternate distribution facilities in a timely manner. Failure to secure alternate distribution facilities in a timely manner could have a material adverse effect on the Company's businesses and results of operations. In addition, each of the Company's television and radio stations and cable networks uses studio and transmitter facilities that are subject to damage or destruction. Failure to restore such facilities in a timely manner could have a material adverse effect on the Company's businesses and results of operations.

The Company Could Suffer Losses Due to Asset Impairment Charges for Goodwill, Intangible Assets, FCC Licenses and Programming

        The Company will test goodwill and indefinite-lived intangible assets, including FCC licenses, for impairment during the fourth quarter of each year and between annual tests if events or circumstances require an interim impairment assessment. A downward revision in the estimated fair value of a reporting unit or intangible assets, including FCC licenses, could result in a non-cash impairment charge. Also, any significant shortfall, now or in the future, in the expected popularity of the programming for which the Company has acquired rights could lead to a downward revision in the fair value of such assets. Any such impairment charge for goodwill, intangible assets and/or programming could have a material adverse effect on the Company's reported net earnings.

Dividends and Dividend Rates Cannot Be Guaranteed

        The Company's Board of Directors assesses relevant factors when considering the declaration of a dividend on the Company's common stock. The Company cannot guarantee that it will continue to declare dividends, including at the same or similar rates.

The Loss of Key Personnel, Including Talent, Could Disrupt the Management or Operations of the Company's Business and Adversely Affect Its Revenues

        The Company's business depends upon the continued efforts, abilities and expertise of its chief executive officer and other key employees and entertainment personalities. The Company believes that the unique combination of skills and experience possessed by its executive officers would be difficult to replace, and that the loss of its executive officers could have a material adverse effect on the Company, including the impairment of the Company's ability to execute its business strategy. While the Company does not maintain a written succession plan with respect to Chairman of the Board, in accordance with the Company's Corporate Governance Guidelines, the non-management directors of the CBS Board consider annually succession planning for the position of Chairman. Because 79% of the voting shares are controlled by Sumner Redstone there can be no assurance now or in the future that he or the successors to the voting control may not seek to effect succession of the Chairman; however, and in all cases, the Board will elect the next Chairman by a majority vote of the entire Board. Additionally, the Company employs or independently contracts with several entertainment personalities and authors with significant loyal audiences. Entertainment personalities are sometimes significantly responsible for the ranking of a television or radio station and, therefore, the ability of the station to sell advertising, and an author's popularity can be significantly responsible for the success of a particular book. Cable Networks produces programming and CBS Films produces motion pictures with highly regarded directors, actors and other talent who are important to achieving audience endorsement of their content. There can be no assurance that these entertainment personalities, authors and talent will remain with or be drawn to the Company or will retain their current audiences or readership. If the Company fails to retain or attract these entertainment personalities, authors and talent or they lose their current audiences or readership, the Company's revenues could be adversely affected.

Regulation of the Outdoor Advertising Industry Could Materially Adversely Affect the Company's Outdoor Business

        The outdoor advertising industry is subject to extensive governmental regulation and enforcement at the federal, state and local levels in the U.S. and to national, regional and local restrictions in foreign countries. These regulations and enforcement actions can affect the operation and continuance of operations of advertising displays and include restrictions on the construction, repair, upgrading, height, size and location of outdoor advertising structures and, in some instances, the content of advertising copy that can be displayed on these structures. In addition, outdoor advertising is the subject of targeted state and municipal taxes and fees. Such laws may increase the Company's costs and reduce the Company's expansion opportunities or may increase competitive pressure from others. The Company cannot give any assurance that existing or future laws or regulations will not materially and adversely affect its outdoor business.

Fluctuations in Foreign Exchange Rates Could Have an Adverse Effect on the Company's Results of Operations

        Certain of the Company's revenues are earned and expenses are incurred in foreign currencies. The value of these currencies fluctuates relative to the U.S. dollar. As a result, the Company is exposed to exchange rate fluctuations, which could have an adverse effect on its results of operations.

The Company's Liabilities Related to Discontinued Operations and Former Businesses Could Adversely Impact Its Financial Condition

        The Company has both recognized and potential liabilities and costs related to discontinued operations and former businesses, certain of which are unrelated to the media business, including leases, guarantees, environmental liabilities, liabilities related to the pensions and medical expenses of retirees, asbestos liabilities, contractual disputes and other pending and threatened litigation. The Company cannot be assured that its reserves are sufficient to cover these liabilities in their entirety or any one of these liabilities when it becomes due or at what point any of these liabilities may come due. Therefore, there can be no assurances that these liabilities will not have a material adverse effect on the Company's financial position, operating performance or cash flow.

The Company Could Be Adversely Affected by Strikes and Other Union Activity

        The Company and its suppliers engage the services of writers, directors, actors and other talent, trade employees and others who are subject to collective bargaining agreements. If the Company or its suppliers are unable to renew expiring collective bargaining agreements, it is possible that the affected unions or others could take action in the form of strikes or work stoppages. Such actions, higher costs in connection with these agreements or a significant labor dispute could adversely affect the Company's television, radio, cable networks and motion picture businesses by causing delays in the production of the Company's television or radio programming, motion pictures or the Company's outdoor business by disrupting its ability to place advertising on outdoor faces. Depending on their duration, strikes or work stoppages could have an adverse effect on the Company's revenues and operating income.

Political and Economic Risks Associated with the Company's International Businesses Could Harm the Company's Financial Condition or Results of Operations

        The Company's businesses operate and have customers worldwide. Inherent risks of doing business in international markets include, among other risks, changes in the economic environment, export restrictions, exchange controls, tariffs and other trade barriers and longer payment cycles. The Company may incur substantial expense as a result of the imposition of new restrictions or changes in the existing economic environment in the regions where it does business. In addition, acts of terrorism or other hostilities, or other future financial, political, economic or other uncertainties, could lead to a reduction in

advertising expenditures, which could materially adversely affect the Company's business, financial condition or results of operations.

NAI, Through Its Voting Control of the Company, Is in a Position to Control Actions that Require Stockholder Approval

        NAI, through its direct and indirect ownership of the Company's Class A Common Stock, has voting control of the Company. Mr. Sumner M. Redstone, the controlling stockholder, chairman of the board of directors and chief executive officer of NAI, serves as Executive Chairman of the Company's Board of Directors, and Ms. Shari Redstone, the president and a director of NAI, serves as Vice Chair of the Company's Board of Directors. In addition, Mr. David R. Andelman is a director of NAI and serves as a director of the Company. NAI is in a position to control the outcome of corporate actions that require stockholder approval, including the election of directors and transactions involving a change of control. Other stockholders are unable to affect the outcome of the corporate actions of the Company for so long as NAI retains voting control.

Sales of Additional Shares of Common Stock by NAI Could Adversely Affect the Stock Price

        NAI, through its direct and indirect ownership of the Company's Class A Common Stock, has voting control of the Company. Based on information received from NAI, shares of the Company's voting Class A common stock and non-voting Class B common stock owned by NAI Entertainment Holdings LLC ("NAI EH"), a wholly-owned subsidiary of NAI, are pledged to NAI EH's lenders. NAI holds more than 50% of the Company's voting Class A shares directly and these shares are not pledged. If NAI EH defaults on its obligations and the lenders foreclose on the collateral, the lenders or anyone to whom the lenders transfer the Company's shares could sell such shares or convert those shares of voting Class A Common Stock into shares of non-voting Class B Common Stock and sell such shares, which could adversely affect the Company's share price. Additionally, if the lenders foreclose on the pledged shares of voting Class A Common Stock, NAI will no longer directly or indirectly own those shares and such lenders or other transferees would have voting rights in the Company. In addition, there can be no assurance that NAI or NAI EH at some future time will not sell or pledge additional shares of the Company's stock, which could adversely affect the Company's share price.

Many Factors May Cause the Stock Price of the Company's Class A Common Stock and Class B Common Stock to Fluctuate

        The stock price of Class A Common Stock and Class B Common Stock may fluctuate significantly as a result of many factors. These factors, some or all of which are beyond the Company's control, include:

•

actual or anticipated fluctuations in CBS Corp.'s operating results;



•

changes in expectations as to CBS Corp.'s future financial performance or changes in financial estimates of securities analysts;



•

success of CBS Corp.'s operating and growth strategies;



•

investor anticipation of strategic, technological or regulatory threats, whether or not warranted by actual events;



•

operating and stock price performance of other comparable companies; and



•

realization of any of the risks described in these risk factors.

In addition, the stock market has experienced volatility that often has been unrelated or disproportionate to the operating performance of particular companies. These broad market and industry fluctuations may adversely affect the trading prices of the Company's common stock, regardless of the Company's actual operating performance.

The Businesses of the Company and Viacom Inc. Will Be Attributable to the Other Company for Certain Regulatory Purposes

        So long as the Company and Viacom Inc. are under common control, each company's businesses, as well as the businesses of any other commonly controlled company, will be attributable to the other company for purposes of certain rules and regulations of the FCC and certain rules regarding political campaign contributions in the U.S., among others potentially. The businesses of one company will continue to be attributable to the other company for certain FCC purposes even after the two companies cease to be commonly controlled, if the two companies share common officers, directors, or attributable stockholders. As a result, the businesses and conduct of Viacom Inc. may have the effect of limiting and affecting the activities, strategic business alternatives and business terms available to the Company.

The Separation Agreement Prohibits the Company from Engaging in Certain Types of Businesses

        Under the terms of the Separation Agreement entered into between the Company and Viacom Inc. in connection with the separation of former Viacom Inc. ("Former Viacom") into two publicly traded entities, CBS Corporation and new Viacom Inc., which was completed on December 31, 2005 (the "Separation"), the Company may not make acquisitions, enter into agreements or accept or agree to any condition that purports to bind Viacom Inc. or subjects Viacom Inc. to restrictions it is not otherwise subject to by legal order without Viacom Inc.'s consent. These restrictions could limit and affect the activities, strategic business alternatives and business terms available to the Company.

In Connection with the Separation, Each Company Will Rely on the Other Company's Performance Under Various Agreements Between the Companies

        In connection with the Separation, the Company and Viacom Inc. entered into various agreements, including the Separation Agreement, a tax matters agreement dated December 30, 2005, which is filed as an exhibit to this report, effective as of the Separation (the "Tax Matters Agreement") and certain related party arrangements pursuant to which the Company and Viacom Inc. will provide services and products to each other from and after the Separation. The Separation Agreement sets forth the allocation of assets, liabilities, rights and obligations of the Company and Viacom Inc. following the Separation, and includes indemnification obligations for such liabilities and obligations. In addition, pursuant to the Tax Matters Agreement, certain income tax liabilities and related responsibilities are allocated between, and indemnification obligations are assumed by, each of the Company and Viacom Inc. Each company will rely on the other to satisfy its performance and payment obligations under these agreements. Certain of the liabilities to be assumed or indemnified by the Company or Viacom Inc. under these agreements are legal or contractual liabilities of the other company. If Viacom Inc. were to breach or be unable to satisfy its material obligations under these agreements, including a failure to satisfy its indemnification obligations, the Company could suffer operational difficulties or significant losses.

Certain Members of Management, Directors and Stockholders May Face Actual or Potential Conflicts of Interest

        The management and directors of the Company may own both CBS Corp. common stock and Viacom Inc. common stock, and both the Company and Viacom Inc. are controlled by NAI. Mr. Redstone, the controlling stockholder, chairman of the board of directors and chief executive officer of NAI, serves as Executive Chairman of the Company's Board of Directors and executive chairman of Viacom Inc.'s board of directors. Ms. Redstone, the president and a director of NAI, serves as Vice Chair of the Board of Directors of each of the Company and Viacom Inc. Mr. David R. Andelman is a director of NAI and serves as a director of the Company. Mr. Frederic V. Salerno is a director of Viacom Inc. and serves as a director of the Company. This ownership overlap and these common directors could create, or appear to create, potential conflicts of interest when the Company's and Viacom Inc.'s management, directors and controlling stockholder face decisions that could have different implications for the Company and

I-33

---

Viacom Inc. For example, potential conflicts of interest could arise in connection with the resolution of any dispute between the Company and Viacom Inc. regarding the terms of the agreements governing the Separation and the relationship between the Company and Viacom Inc. thereafter. These agreements include, among others, the Separation Agreement, the Tax Matters Agreement and any commercial agreements between the parties or their affiliates. On occasion, the Company and Viacom Inc. may compete with each other in various commercial enterprises. Potential conflicts of interest could also arise if the Company and Viacom Inc. enter into any commercial arrangements with each other in the future. Each of Mr. Redstone and Ms. Redstone may also face conflicts of interest with regard to the allocation of his or her time between the Company and Viacom Inc. CBS Corp.'s certificate of incorporation contains provisions related to corporate opportunities that may be of interest to both the Company and Viacom Inc. CBS Corp.'s certificate of incorporation provides that in the event that a director, officer or controlling stockholder of the Company who is also a director, officer or controlling stockholder of Viacom Inc. acquires knowledge of a potential corporate opportunity for both the Company and Viacom Inc., such director, officer or controlling stockholder may present such opportunity to the Company or Viacom Inc. or both, as such director, officer or controlling stockholder deems appropriate in his or her sole discretion, and that by doing so such person will have satisfied his or her fiduciary duties to the Company and its stockholders. In addition, CBS Corp.'s certificate of incorporation provides that the Company renounces any interest in any such opportunity presented to Viacom Inc. These provisions create the possibility that a corporate opportunity of one of such companies may be used for the benefit of the other company.

Item 3.    Legal Proceedings.

        Securities Action.    On December 12, 2008, the City of Pontiac General Employees' Retirement System filed a self-styled class action complaint in the United States District Court for the Southern District of New York against the Company and its Chief Executive Officer, Chief Financial Officer, Chief Accounting Officer, and Treasurer, alleging violations of federal securities law. The complaint, which was

I-34

---

filed on behalf of a putative class of purchasers of the Company's common stock between February 26, 2008 and October 10, 2008 (the "Class Period"), alleges that, among other things, the Company's failure to timely write down the value of certain assets caused the Company's reported operating results during the Class Period to be materially inflated. The plaintiffs seek unspecified compensatory damages. On February 11, 2009, a motion was filed in the case on behalf of The City of Omaha, Nebraska Civilian Employees' Retirement System, and The City of Omaha Police and Fire Retirement System (collectively, the "Omaha Funds") seeking to appoint the Omaha Funds as the lead plaintiffs in this case; on March 5, 2009, the court granted that motion. On May 4, 2009, the plaintiffs filed an Amended Complaint, which removes the Treasurer as a defendant and adds the Executive Chairman. On July 13, 2009, all defendants filed a motion to dismiss this action. On March 16, 2010, the court granted the Company's motion and dismissed this action as to the Company and all defendants. On April 30, 2010, the plaintiffs filed a motion for leave to serve an amended complaint. On September 23, 2010, the court issued an order granting leave to amend. On October 8, 2010, the Company was served with an Amended Complaint, which redefines the Class Period to be April 29, 2008 to October 10, 2008 and alleges that the impairment charge should have been taken during the first quarter of 2008. The Company filed a motion to dismiss this Amended Complaint on November 19, 2010. The Company believes that the plaintiffs' claims are without merit and intends to vigorously defend itself in the litigation.

        Claims Related to Former Businesses: Asbestos.    The Company is a defendant in lawsuits claiming various personal injuries related to asbestos and other materials, which allegedly occurred principally as a result of exposure caused by various products manufactured by Westinghouse, a predecessor, generally prior to the early 1970s. Westinghouse was neither a producer nor a manufacturer of asbestos. The Company is typically named as one of a large number of defendants in both state and federal cases. In the majority of asbestos lawsuits, the plaintiffs have not identified which of the Company's products is the basis of a claim. Claims against the Company in which a product has been identified principally relate to exposures allegedly caused by asbestos-containing insulating material in turbines sold for power-generation, industrial and marine use, or by asbestos containing grades of decorative micarta, a laminate used in commercial ships.

        Claims are frequently filed and/or settled in groups, which may make the amount and timing of settlements, and the number of pending claims, subject to significant fluctuation from period to period. The Company does not report as pending those claims on inactive, stayed, deferred or similar dockets which some jurisdictions have established for claimants who allege minimal or no impairment. As of December 31, 2010, the Company had pending approximately 52,220 asbestos claims, as compared with approximately 62,360 as of December 31, 2009 and 68,520 as of December 31, 2008. During 2010, the Company received approximately 5,170 new claims and closed or moved to an inactive docket approximately 15,310 claims. The Company reports claims as closed when it becomes aware that a dismissal order has been entered by a court or when the Company has reached agreement with the claimants on the material terms of a settlement. Settlement costs depend on the seriousness of the injuries that form the basis of the claim, the quality of evidence supporting the claims and other factors. The Company's total costs for the years 2010 and 2009 for settlement and defense of asbestos claims after insurance recoveries and net of tax benefits were approximately $13.7 million and $17.8 million, respectively. The Company's costs for settlement and defense of asbestos claims may vary year to year as insurance proceeds are not always recovered in the same period as the insured portion of the expenses.

        Filings include claims for individuals suffering from mesothelioma, a rare cancer, the risk of which is allegedly increased by exposure to asbestos; lung cancer, a cancer which may be caused by various factors, one of which is alleged to be asbestos exposure; other cancers, and conditions that are substantially less serious, including claims brought on behalf of individuals who are asymptomatic as to an allegedly asbestos-related disease. The predominant number of claims against the Company are non-cancer claims. In a substantial number of the pending claims, the plaintiff has not yet identified the claimed injury. The Company believes that its reserves and insurance are adequate to cover its asbestos liabilities. This belief is

I-35

---

based upon many factors and assumptions, including the number of outstanding claims, estimated average cost per claim, the breakdown of claims by disease type, historic claim filings, costs per claim of resolution and the filing of new claims. While the number of asbestos claims filed against the Company has trended down in recent years, it is difficult to predict future asbestos liabilities, as events and circumstances may occur including, among others, the number and types of claims and average cost to resolve such claims, which could affect the Company's estimate of its asbestos liabilities.

        Other.    The Company from time to time receives claims from federal and state environmental regulatory agencies and other entities asserting that it is or may be liable for environmental cleanup costs and related damages principally relating to historical and predecessor operations of the Company. In addition, the Company from time to time receives personal injury claims including toxic tort and product liability claims (other than asbestos) arising from historical operations of the Company and its predecessors.

        On an ongoing basis, the Company defends itself in numerous lawsuits and proceedings and responds to various investigations and inquiries from federal, state and local authorities (collectively, "litigation"). Litigation is inherently uncertain and always difficult to predict. However, based on its understanding and evaluation of the relevant facts and circumstances, the Company believes that the above-described legal matters and other litigation to which it is a party are not likely, in the aggregate, to have a material adverse effect on its results of operations, financial position or cash flows. Under the Separation Agreement between the Company and Viacom Inc., the Company and Viacom Inc. have agreed to defend and indemnify the other in certain litigation in which the Company and/or Viacom Inc. is named.

Item 7.   Management's Discussion and Analysis of Results of Operations and Financial Condition.
(Tabular dollars in millions, except per share amounts)

        Management's discussion and analysis of the results of operations and financial condition of CBS Corporation (together with its consolidated subsidiaries, unless the context otherwise requires, the "Company" or "CBS Corp.") should be read in conjunction with the consolidated financial statements and related notes. Descriptions of all documents incorporated by reference herein or included as exhibits hereto are qualified in their entirety by reference to the full text of such documents so incorporated or included. Please see Item 1A. "Risk Factors" in Part I of this report for the Cautionary Statement Concerning Forward-Looking Statements.

Overview

        In 2010, CBS Corporation's results were driven by the economic recovery and the strength of the Company's content, which led to increases in revenues of 8% to $14.06 billion, operating income of 80% to $1.82 billion and diluted earnings per share of 215% to $1.04. The Company generated net cash flow from operating activities of $1.74 billion which was used, along with cash on hand, to reduce its outstanding debt by $1.40 billion, including a $400.0 million reduction to the accounts receivable securitization program, as well as to fund $284.3 million of capital expenditures and pay $141.7 million of dividends to the Company's shareholders.

        Revenue growth in 2010 was led by increases of 18% at Local Broadcasting, 6% at Entertainment, 9% at Cable Networks and 6% at Outdoor. Total advertising sales for 2010 increased 12% reflecting growth in both local and national advertising sales, primarily driven by the economic recovery and an increase in market share. Advertising revenues also benefited from the telecast of Super Bowl XLIV on the CBS Television Network and higher political advertising sales from the 2010 mid-term elections. Affiliate and subscription fees increased 9% driven by rate increases and growth in subscriptions at the Company's cable networks as well as higher retransmission revenues. Content licensing and distribution revenues decreased 2%, as increases in international syndication sales of television series and the addition of theatrical revenues in 2010, were more than offset by a decline in domestic syndication sales due to the first-cycle syndication sales of five major titles in 2009.

        For 2010, operating income of $1.82 billion and diluted earnings per share of $1.04 both grew at a higher rate than revenues as the revenue growth was primarily driven by high margin advertising and affiliate revenues. Operating income and diluted earnings per share comparisons were also impacted by 2009 pre-tax non-cash impairment charges of $210.0 million ($131.2 million, net of tax) or $.19 per diluted share.

        For 2010, free cash flow of $1.45 billion increased 75% from $827.8 million for 2009 principally reflecting higher operating income partially offset by higher payments for taxes and a discretionary contribution of $167.0 million to pre-fund the Company's qualified pension plans in 2010. The Company generated net cash flow from operating activities of $1.74 billion for 2010 versus $939.4 million for 2009, which included a $150.0 million reduction to amounts outstanding under the Company's accounts receivable securitization program. Free cash flow, a non-GAAP financial measure, reflects the Company's net cash flow provided by (used for) operating activities before increases and decreases to the accounts receivable securitization program and less capital expenditures. See "Reconciliation of Non-GAAP Financial Information" on pages II-12 and II-13 for a reconciliation of net cash flow provided by (used for) operating activities, the most directly comparable financial measure in accordance with accounting principles generally accepted in the United States of America ("GAAP"), to free cash flow.

Management's Discussion and Analysis of
Results of Operations and Financial Condition (Continued)
(Tabular dollars in millions, except per share amounts)

CBS Corp. operates in the following segments:

ENTERTAINMENT: The Entertainment segment consists of the CBS Television Network, CBS Television Studios, CBS Studios International, CBS Television Distribution, CBS Films and CBS Interactive. Entertainment revenues are generated primarily from advertising sales, content licensing and distribution, and affiliate and subscription fees. Entertainment contributed 53%, 54% and 49% to consolidated revenues for the years ended December 31, 2010, 2009 and 2008, respectively.

CABLE NETWORKS: The Cable Networks segment consists of Showtime Networks, CBS College Sports Network and Smithsonian Networks.
