Viacom Inc, short for “Video & Audio Communications”, is a mass media company

The second incarnation of Viacom Inc. (/ˈvaɪəkɒm/ VY-ə-kom or /ˈviːəkɒm/ VEE-ə-kom; an acronym of Video & Audio Communications) was an American multinational mass media conglomerate with interests primarily in film and television, which was formed as a spin-off of the first Viacom on December 31, 2005. It was one of two companies which succeeded the first Viacom, alongside CBS Corporation; both were owned by National Amusements, a theater company controlled by businessman Sumner Redstone. 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 second Viacom comprised Viacom Media Networks and Paramount Pictures, through which it operated approximately 170 networks and reached approximately 700 million subscribers in approximately 160 countries and growing. CBS Corporation retained the over-the-air broadcasting, television production, pay television subscription service, and publishing assets, which were previously owned by the first Viacom. The second Viacom was the world’s ninth-largest media company in terms of revenue, and headquartered at One Astor Plaza in Midtown Manhattan, New York City.
