Viacom ( ) ( ), short for "Video & Audio Communications", is an American media conglomerate with various worldwide interests in cable and satellite television networks (MTV Networks and BET), and movie production and distribution (the Paramount Pictures and DreamWorks movie studios). Sumner Redstone is the Chairman and, through National Amusements, the majority shareholder.
The new Viacom (legal successor to the former Gulf+Western/Paramount Communications) is considered to be the "high-growth" side of the much larger former Viacom. The former Viacom was renamed CBS Corporation, from which this firm was split off on December 31, 2005. CBS, not Viacom, retains control of the over-the-air broadcasting, TV production, and publishing assets formerly owned by the larger company. However, National Amusements remains the common majority shareholder of both firms.
