September, 1993: WCW withdraws from National Wrestling Alliance..
March 2001: Turner Broadcasting sells World Championship Wrestling (the "intellectual property" to be exact) and some of its assets to Vince McMahon and the WWFe. Vince didn't buy the high priced talent. He didn't buy Flair, Goldberg, Steiner, etc. They were paid by TBS/Time Warner until their deals expired.
