What is the BIGGEST fight in history - adjusted for inflation and technology?

[Bald Shavers]

Okay, Pac vs May would be the biggest fight in history assuming Floyd does not duck. But it would only be the biggest fight ever because:

1. The world population is the biggest it has ever been. (during Sugar Ray Robinson's, Willie Pep's, and Rocky Marciano's time it was 2.5 billion; during Muhammad Ali's time it was 3.7 billion; now it is 7 billion)

2. $1 in Jack Dempsey's and Benny Leonard's time would buy $12 worth of goods when Mayweather said that he would absolutely fight Pacquiao on May 2, 2015 (he announced it during Khan's victory over Alaxander)

3. In terms of technology, you had to watch Jack Johnson vs Jim Jeffries in person and couldn't do so if you were a minority; you could listen to Louis vs Schmelling live on the giant radio in your living room; you could watch Gavilan vs Basilio on black and white TV which weren't that numerous at the time; you could watch Ali vs Frazier I on closed circuit, etc. The reach of these technologies were relatively low.

Based on holding technology, inflation and population constant, what was really the biggest fight in history? No way it would be Pac/Floyd.

Ali vs Frazier 1

Forman v Ali

Louis v Max

[Pac=Duran]

Louis vs Schmelling 2 and it's not even close. The World was on the verge of the Second World War. The world froze for this fight.

Johnosn v jeffries and Louis v max had significance far outside the sport. But ali v Frazier 1 always is discussed as the biggest fight ever.

You could put ali v Frazier in any era and it would be as significant and as big. The other 2 fights feel like "era only" big.
