Remember the XFL? It was an alternate football league, launched by the combined forces of Vince McMahon's WWF and NBC back in 2001. Instead of tedious rules minutiae like "completing the process of the catch," it emphasized cheerleaders, Hail Mary passes, and "extreme" bombast. Its players swore that, unlike pro-wrestling, it wasn't scripted but (despite impressive initial ratings) it never managed to find a sustainable audience. The whole thing imploded after one season.
