former American media conglomerate from 1952–2006
The first incarnation of Viacom Inc. (derived from "Video & Audio Communications") was an American media conglomerate. It began as CBS Television Film Sales, the syndication division of the CBS television network in 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.
In 1999, Viacom acquired the then-parent company of CBS, the former Westinghouse Electric Corporation, which had been renamed CBS Corporation in 1997. Viacom was split into the second CBS Corporation and Viacom incarnations, and ceased operations in 2006. The spin-off was structured so that CBS Corporation would be the legal successor to the first Viacom, with the second Viacom being an entirely separated company. The two companies eventually re-merged on December 4, 2019, leading to the operations of the current ViacomCBS.
