He began expanding the company nationally by promoting in areas outside of the company's Northeast U.S. stomping grounds and by signing talent from other companies, such as the American Wrestling Association (AWA). In 1984, he recruited Hulk Hogan to be the WWF's charismatic new megastar, and the two quickly drew the ire of industry peers as the promotion began traveling and broadcasting into rival territories. Nevertheless, McMahon (who still also fronted as the WWF's squeaky clean babyface announcer) created "The Rock 'n' Wrestling Connection" by incorporating pop music stars into wrestling storylines. As a result, the WWF was able to expand its fanbase into a national mainstream audience as the promotion was featured heavily on MTV programming. On March 31, 1985, he ran the first WrestleMania at Madison Square Garden, available on closed circuit television in various markets throughout the United States. McMahon's success of birthing WrestleMania in the 1980's had a siginifant impact on the 1980s professional wrestling boom.
