In terms of "how to become a PPV star"...
Honestly a big part of it IMO is fighting an already established PPV star and "leeching" his fans. Of course the most obvious examples being Mayweather and Pacquiao gaining superstar status after fighting De La Hoya.
Another thing that is much harder to quantify is a certain quality that casual fans gravitate towards. For Tyson it was pure violence: they paid to see guys get annihilated in the ring. For De La Hoya it was his Olympic gold pedigree and good looks, not to mention heart and actual skills. For Mayweather it's his "love to hate him" persona, and the suspense of who can finally dethrone him and take his 0 (note I mentioned casual fans earlier in this paragraph, most casuals don't watch Floyd purely for his boxing skills). For Pacquiao it's his relentless aggression, action packed style, and his improbable run taking out guys much bigger than him.
One more thing is established fanbase. If you're 30 fights into your career and still can't fill a stadium worth a lick, chances are you'll never become a PPV attraction.
