World Championship Wrestling (WCW) was a wrestling promotion which existed from 1988 to 2001. Widely known as "National Wrestling Alliance" (which was a technical inaccuracy), Jim Crockett Promotions sold its promotion to Ted Turner and Turner Broadcasting in November 1988, at which time it was renamed "World Championship Wrestling." Through various mergers, WCW was owned by multi-media entertainment conglomerate AOL Time Warner, which sold the entire promotion to the World Wrestling Federation for a reported $2.5-million in March 2001.
WCW's most successful period came at the direction of Eric Bischoff between September 1995 through April 1999 when it started WCW Monday Nitro, especially after launching its New World Order angle with Hulk Hogan, Kevin Nash, and Scott Hall "invading" WCW, leaving men like Sting, Ric Flair, Lex Luger, and DDP to defend the brand. During this same period, WCW introduced several talented workhorses from across the world (like Chris Benoit, Eddie Guerrero, Chris Jericho, Rey Mysterio, and others) to the national wrestling audience (to its credit, ECW had been using most guys WCW got credit for introducing).
Unfortunately, a stream of bad business decisions (complicated by inefficiency in its corporate structure) knocked WCW off-track, and their wild attempts to restore faded glory quickly eliminated its future profitability. Eventually, WCW programming was removed from television, and it was put up for sale. Today, all WCW broadcasts are owned by WWE.
