It's interesting to reminisce about the old days. It was a great time when one could turn on the TV and watch championship fights without a ppv fee. Boxing isn't a fraction of the sport it used to be. PPV has destroyed the sport. Ali vs Holmes may have been the last free championship fight I watched. There was a time when a boy was asked what do you want to be you grow up, and the #1 answer was Heavyweight champion of the world. Most kids could not even name the current champ.
What has done more to kill boxing?
A PPV
B Too many boxing organizations with their own title holders
C MMA
I say B
I stopped paying attention when the WBA had three super-middle weight champs at the same time: Champion, Super-Champion, and Diamond Champion.
Plus, boxing is not unlike MMA in that promotional companies will only let their fighters fight guys within their stable. PBC will only let guys within the PBC stable of fighter box each other. Same with Arum's guys, Top Rank, Golden Boy, etc. Dno King made this trend go mainstream when he had Tyson under contract. "Oh, you want to fight Mike? You can if you leave your current manager/promoter and sign with me. Win or lose, you are now under my contract."
Lastly, did you hear about the newest weight class, Bridgerweight? Didn't think so. But, that means 18 weight classes.
It says something about the sport when the most popular professional boxer right now is a guy from youtube.
