SuperStation TBS's parent company, Turner Broadcasting System, had asked Georgia Championship Wrestling to change its public brand name to World Championship Wrestling, helping fuel rumors that the Jim Barnett-controlled company would go national itself; GCW acquiesced to the World Championship Wrestling name change in 1982.[8] Meanwhile, by 1983, JCP went from recording its weekly shows in a television studio to shooting on-location, in between matches at live arena events. After purchasing a mobile television production unit for $1 million, Crockett unveiled what became the NWA's dominant annual supercard, Starrcade.[9]
