The WCW logo used during the Invasion storyline; this logo was introduced before the Alliance was formed and was to be WCW's regular logo if it had a weekly program.
World Championship Wrestling started as a regional promotion, Jim Crockett Promotions (which was affiliated with the National Wrestling Alliance). The "World Championship Wrestling" name was used in various forms by various promotions affiliated with the NWA. When Ted Turner and JCP established Universal Wrestling Corporation, the company began using the name, World Championship Wrestling full-time after the assets were transferred. Turner was then bought out by Time Warner in 1996; WCW's association with the NWA was dissolved in 1991 (and fully ended in 1993), which resulted in the NWA's World Heavyweight Championship becoming a WCW belt, as WCW owned it (the "Big Gold Belt", as it came to be known; it is now known as the WWE World Heavyweight Championship).
In late 2000, World Wrestling Federation Entertainment, Inc. (Now known simply as WWE Inc.) established a new subsidiary called W. Acquisition Company when WWFE made an attempt to buyout Turner the first time around before the Viacom deal interfered with their plans. Eventually, on March 26, 2001, WWFE, Inc. acquired the trademarks, copyrights, video library, and the 24 contracts from World Championship Wrestling, Inc. after Jamie Kellner cancelled their programming off TBS and TNT. W. Acquisition Company changed its name to WCW, Inc. The company itself that retains certain contracts that were not purchased by WWFE was then switched back to Universal Wrestling Corporation.
The primary world title of WCW. It was established in 1991 under WCW and would continue to be used after WCW's purchase by the WWF until December 2001, when it was unified with the WWF Championship. The physical belt, known as the Big Gold Belt, returned in September 2002 as the World Heavyweight Championship.
