The league was originally named "Xtreme Football League," but an arena football league with that name was already in development. The "X" didn't stand for anything.
There will be a third season of the XFL in 2021.
The XFL introduced several concepts later adopted by the NFL, including an overhead camera that zoomed down the field and players introducing themselves.
Vince McMahon created the XFL, a football league intended as an NFL alternative, in 2000. The show was a combination of regular football and WWF-style theatrics. Despite heavy promotion, including ads on all of the WWF shows, ratings were low. The show was canceled after 1 season, the league disbanded, and McMahon's company lost $35 million.
Instead of an opening kick-off, the teams were forced to scrum for the football. Like a hockey face-off, one player from each team scrambled to recover the football and win possession for his team. The concept can be traced back to the 1920s NFL.
