Overview
Viacom (1952–2005) was the first company to use the Viacom name and was an American media and entertainment conglomerate based in New York City. Its origins lay in CBS Television Film Sales, a CBS division established in 1952 to sell filmed and recorded television programs to unaffiliated stations and overseas broadcasters. The operation was renamed CBS Films in 1958 and CBS Enterprises in 1968. In 1970 it became Viacom, a name derived from “Video & Audio Communications,” and it was separated from CBS in 1971 in response to Federal Communications Commission rules that restricted television networks from owning their own syndication businesses. The independent company initially remained strongly associated with television distribution. It marketed off-network programs and built a business around licensing, production and the repackaging of television libraries for local stations and international customers. During the 1970s it also moved into cable television. Showtime, a pay-television movie service, was launched in 1976 in partnership with Warner-Amex. This gave Viacom exposure to recurring subscription revenue and to the emerging premium-cable market, complementing its traditional syndication activities. A decisive transformation came in the mid-1980s. Viacom acquired control of Showtime/The Movie Channel and MTV Networks, whose portfolio included MTV, VH1 and Nickelodeon. These transactions shifted the company from being principally a distributor of television programs to being a major owner of branded cable channels. The networks supplied Viacom with recurring carriage fees, advertising inventory, recognizable consumer brands and opportunities to exploit programming across television, home video, licensing and merchandising. In 1987, Sumner Redstone's National Amusements acquired control of Viacom, establishing the ownership structure that remained central to the company through its later expansion. Viacom then pursued a broad entertainment strategy. Its 1994 acquisition of Paramount Communications brought Paramount Pictures, Paramount Television and related entertainment assets into the group, strengthening Viacom's position in theatrical film, television production and distribution. The transaction also gave Viacom ownership of the New York Knicks through Paramount's Madison Square Garden interests at the time. Viacom subsequently expanded its video-rental presence through Blockbuster Entertainment and added further cable, broadcasting, outdoor advertising, publishing and production assets. The company also developed or operated businesses associated with Comedy Central, BET, UPN, CBS Radio, King World Productions, Simon & Schuster and Viacom Outdoor. In 2000, Viacom acquired CBS, formerly part of Westinghouse Electric and renamed CBS Corporation in 1997. The transaction reunited Viacom with its former parent and created a highly integrated media group spanning broadcast television, radio, cable networks, film studios, television production, publishing and distribution. The combined company controlled both content libraries and multiple channels through which that content could be financed, promoted and delivered. The integrated structure proved difficult to manage. The company faced different strategic priorities among its broadcast, cable, film and publishing businesses, as well as internal disagreements over leadership and capital allocation. In 2005, Viacom announced a corporate separation. Effective at the end of 2005 and into early 2006, the original company was divided between a successor CBS Corporation focused on broadcast television, radio, outdoor advertising and publishing, and a newly created Viacom focused primarily on cable networks and filmed entertainment. Both companies remained under National Amusements' control. The 1952–2005 Viacom therefore ceased to exist as a unified corporate entity, while its businesses continued through the successor companies and their later owners.
History
Viacom began in 1952 as CBS Television Film Sales, the CBS television network's syndication division. Its role was to license filmed and recorded programs to non-CBS stations and international broadcasters, allowing CBS to generate additional value from television programs beyond their original network runs. It became CBS Films in 1958 and CBS Enterprises in 1968. In 1970 the business adopted the Viacom name and was separated from CBS in 1971 after federal rules restricted television networks from owning syndication companies. As an independent company, Viacom initially concentrated on program distribution but gradually expanded into production, cable systems and subscription television. It helped launch Showtime in 1976 with Warner-Amex, entering the developing premium-cable business. The company became substantially larger in the 1980s when it acquired Showtime/The Movie Channel and MTV Networks. MTV, VH1 and Nickelodeon gave Viacom a portfolio of highly recognizable, demographically targeted cable brands and reduced its dependence on one-time distribution transactions. National Amusements, controlled by Sumner Redstone, acquired control of Viacom in 1987. Under Redstone, the company pursued an aggressive acquisition strategy. The 1994 purchase of Paramount Communications added Paramount Pictures and television-production capabilities, while related transactions and investments broadened Viacom's presence in video rental, broadcasting, radio, cable programming and entertainment venues. The company also became associated with BET, Comedy Central, UPN, King World Productions, Simon & Schuster and outdoor advertising operations. Viacom's acquisition of CBS in 2000 reunited the company with the business from which it had originated. The enlarged group combined CBS broadcast television and radio assets with Viacom's cable channels, Paramount's film and television operations, publishing and distribution businesses. This vertical structure offered opportunities to cross-promote and reuse content across multiple platforms, but it also created a complex conglomerate with businesses operating under different economic and strategic conditions. In 2005 the company announced that it would be separated. The CBS-oriented assets were placed in the second CBS Corporation, which was treated as the legal successor to the original Viacom, while cable and filmed-entertainment assets were placed in a newly created company that retained the Viacom name. The separation took effect at the end of 2005 and the beginning of 2006. Both successor companies remained controlled by National Amusements. Consequently, the historical Viacom covered by this dossier is defunct, although many of its brands and businesses survived under successor ownership.
