Viacom
From Wikipedia, the free encyclopedia.
Viacom is an international media conglomerate. The companies owned by Viacom touch virtually every major segment of the media industry. Their company portfolio currently includes:
Viacom began life as the television syndication division of CBS, CBS Films. In 1971, the division was renamed Viacom International, and in 1973 it was spun off, amid new FCC rules forbidding television networks from owning syndication companies.
Viacom made large amounts of money during the 1970s and 1980s distributing old CBS classics to syndication, including such landmark shows as I Love Lucy, The Andy Griffith Show and All in the Family. They also syndicated shows for others, the biggest examples being The Cosby Show and Roseanne.
In 1985, Viacom bought Warner-Amex Satellite Entertainment, which owned MTV and Nickelodeon, renaming the company MTV Networks. In 1986, Viacom was bought by movie theater owner National Amusements, which brought Sumner Redstone to the company. Redstone made a string of large acquisitions in the early 1990s, announcing plans to buy Paramount Pictures in 1993, and buying the Blockbuster chain in 1994.
The Blockbuster acquisition gave Viacom access to large television holdings controlled by Aaron Spelling's company, Spelling Entertainment; along with his own productions (such as The Love Boat and Beverly Hills 90210), Spelling controlled the pre-1973 ABC and NBC back catalogs by way of Worldvision Enterprises and Republic Pictures. After these acquisitions, Viacom owned many movie and television production and syndication units, which were slowly integrated into Paramount; many TV shows previously distributed by Viacom, Republic or Worldvision have since gained Paramount closing logos.
In 1999, Viacom made what has been its biggest acquisition so far, by announcing plans to buy its former parent CBS. The merger was approved in 2000, bringing cable channels TNN (now Spike TV) and CMT under Viacom's wing, as well as CBS's production units and TV syndicators Eyemark (formerly Group W) and King World. As of this writing, CBS's production unit and King World (which has since absorbed Eyemark) are operating under their own names, as parts of CBS, and no attempt has been made thus far to move them around in Viacom's corporate structure; however, TNN and CMT were merged into MTV Networks almost immediately.
In 2001, Viacom completed its purchase of Black Entertainment Television. As with TNN and CMT, it was immediately integrated into MTV Networks, causing some outcry among BET workers in the Washington, DC area (where BET was based before the merger). BET was not integrated into MTV Networks.
Although a majority economic interest in Viacom is held by independent shareholders, the Redstone family maintains voting control of the company through National Amusements' holdings of Viacom's class A stock.

The new CBS Corporation began trading on the New York Stock Exchange once again on January 3 after officially finishing its split with Viacom two days earlier. The split had been in the works since around March 2005 when Viacom announced it was breaking into two publicly traded companies due to stock price stagnation. 

In June 2005, Viacom's board approved the split and saying the CBS Corporation name would be revived for one of those companies. One of these units would receive most of Viacom's broadcasting and mass-media portion of subsidiaries (CBS, UPN, Infinity Broadcasting, now CBS Radio) along with Viacom Outdoor (now CBS Outdoor), Showtime Networks, and Paramount's television studio and a few other operations and announced long-time excutive Leslie Moonves would head that new company.

The split is filled with twists and turns. Viacom was founded in 1971 as CBS' television syndication division and was spun off in 1973. Westinghouse Electric Corporation bought CBS and changed its name to CBS Corporation. In a ironic twist, Viacom accquired their parent company in 1999 and CBS' stock symbol was de-listed as it became a division of Viacom. Ironically, the new CBS Corporation is actually the original Viacom. A new Viacom was founded and spun off containing MTV Networks (which contains CMT and Spike TV, two cable networks originally owned by CBS) along with BET, Paramount's film studio and home entertainment divisions, online virtual pet game Neopets, and a music publisher. It also partially owns Sega of America along with the Sonic the Hedgehog trademarks and is currently in the process of acquiring DreamWorks.
