The first incarnation of Viacom Inc. (derived from "Video & Audio Communications") was an American mass media and entertainment conglomerate based in New York City. It began as CBS Television Film Sales, the broadcast syndication division of the CBS television network on March 16, 1952; it was renamed CBS Films in 1958, renamed CBS Enterprises in 1968, renamed Viacom in 1970, and spun off into its own company in 1971. Viacom was a distributor of CBS television series throughout the 1970s and 1980s, and also distributed syndicated television programs. The company came under Sumner Redstone's control in 1987 through his cinema chain company National Amusements.
At the time of its split, Viacom's assets included the CBS and UPN broadcast networks, the Paramount Pictures film and television studio, local radio station operator CBS Radio, cable channels such as MTV, Nickelodeon, Comedy Central, BET, and Showtime, outdoor media operator Viacom Outdoor, television production and distribution firm King World Productions, and book publisher Simon & Schuster. It also owned its IP holding subsidiary Viacom International and brand licensor Westinghouse Licensing Corporation.
