I think boxing is probably done being a major sport in America. Pay per view, which is a great idea for big fights and was a great idea back when it started, is the downfall of boxing in America. Promoters and fighters don't care about the sport's health in the US enough to take the necessary measures to bring boxing back to the forefront in the US. Boxers and promoters are pretty much only worried about money.

Boxing won't be a mainstream sport anymore but boxing will never die. Boxing will always be somewhat popular, and whenever there's a truly big fight, it will probably be the highlight of the sports weekend and a big money making event. But it's never gonna be like it was in the 80s and early 90s unless a bunch of stuff changes.
