I forgot about the boxing gyms closing down too, but this has been happening in the last 7 or 8 years when boxing was on it's downside and it still is on it's downside. And someone here also mentioned marketing also plays a role to attract new fans to the sport.

Of course it starts with amateur boxing to bring in the exciting new talent. It's a damn shame that the high schools in America doesn't have some sort of amateur boxing program to attract the talent that football and basketball does.
