The WWF would tour nationally in a venture that would require a huge capital investment, one that placed the WWF on the verge of financial collapse. The future of McMahon's experiment came down to the success or failure of McMahon's groundbreaking concept, WrestleMania. WrestleMania was a major success and was (and still is) marketed as the Super Bowl of professional wrestling. The concept of a wrestling supercard was nothing new in North America; the NWA had begun running Starrcade a few years prior. In McMahon's eyes, however, what separated WrestleMania from other supercards was that it was intended to be accessible to those who did not watch wrestling. He invited celebrities such as Mr. T, Muhammad Ali, and Cyndi Lauper to participate in the event, as well as securing a deal with MTV to provide coverage. The event and hype surrounding it led to the term "Rock 'n' Wrestling Connection", due to the cross-promotion of popular culture and professional wrestling.
