The first WrestleMania in WWE history was almost ruined in an instant. One of the biggest business decisions of Vince McMahon’s career as a promoter, WrestleMania would help launch WWE into the global superpower that it is today. Had the first edition been a failure, the company’s lifespan would have not been so long. As fans know, the first WrestleMania was a resounding success, but the event actually almost ended in disaster.
