The only reason 2007 and 2012 were the biggest paid ppvs ever are because you're using money paid rather than number of purchases.
It's the same reason new movies always outsell the old movies. Doesn't mean one movie or the other drew more relative money vs another movie. It just means if you saw Gone with the Wind in theaters, you likely paid around $0.75 for your ticket.
I'm sure The Emoji movie outsold Gone with the Wind. Movie tickets in 2012 were also closer to $12. Today tickets at my local cinema are closer to $18.
That means for every 1 person who saw The Emoji movie, 16 people would have to see Gone with the Wind to equal the same dollar amount.
If we compared PPVs sold, I'm CERTAIN Hulk Hogan is the leading draw of all time. His 80s run will forever be unmatched. His 90s NWO run was almost on par with his 80s run. Thenhe even had a decent nostolgia run in the 2000s.
Moneywise? No. An 80s PPV was $20. By 1997 it was $35, and by 2007 it was $90.
So yeah, dollars to sales don't line up because of inflation/rising prices. But if we keep 1 buy = 1 buy, I'm positive Hogan is the all time sales draw. Rock would come close, if it weren't for his constant long departures. You gotta remember, from 1975-2012, Hogan was almost always in pro-wrestling. Small gaps here and there, yes. But Rock left for multiple years at a time. And PPV wasn't even a thing until 1986 or so. So he lost out on 11 years of ppv numbers because it wasn't even invented yet.
That being said, Hogan is a slimy piece of shit, and I'm not endorsing him. Just stating facts about who sold tickets and ppvs.
