Viacom Inc. (originally an initialism of Video & Audio Communications and stylized as VIACOM) was an American media conglomerate. During the 1970s and 1980s, Viacom was a prominent distributor of syndicated CBS television series such as I Love Lucy, The Andy Griffith Show, The Twilight Zone and All in the Family. They also distributed syndicated shows which originated during the 1980s, with the biggest examples being The Cosby Show and Roseanne (which were produced by Carsey-Werner Productions, who eventually began distributing their own programming). On December 31, 2005, the original incarnation of Viacom split into two new companies, resulting in the creation of CBS Corporation and the current incarnation of Viacom.
