The company began trading on the NYSE on January 3, 2006. Until then, the... corporation was known as Viacom, and is the legal successor to said company. A new company, keeping the Viacom name was spun off from CBS.

CBS has its headquarters in CBS Building, Midtown, Manhattan, New York City, New York, United States. Viacom was created in 1970 as the television syndication division of CBS, and was spun off in 1971. However, in 1999, Viacom acquired its former parent, by this time also named CBS Corporation, formerly Westinghouse Electric.
