Last Saturday's Floyd Mayweather vs. Miguel Cotto fight was one of the most popular bouts in history.

HBO is reporting that Mayweather-Cotto sold 1.5 million Pay-Per-View buys. The fight is the sixth best-selling PPV boxing match of all time, according to Kevin Iole of Yahoo Sports. It generated $94 million in revenue.

Mayweather defeated Cotto for the Junior Middleweight Title by a unanimous decision. It was the second-largest non-heavyweight PPV fight in history.

The 2007 fight between Floyd Mayweather and Oscar De La Hoya in 2007 was the number one selling fight of all time with 2.5 million buys. Mike Tyson vs. Lennox Lewis is number two in history at 1.98 million. Mike Tyson and Evander Holyfield's two bouts come in at number three and four.

With Mayweather-Cotto doing so well, experts are predicting that a potential matchup between Mayweather and Manny Pacquiao could break records. Some have speculated that the fight would draw over three times as much money as Mayweather-Cotto.

A fight between the two biggest stars in boxing is still not on the horizon.

Pacquiao is set to face Timothy Bradley on June 9. Mayweather is set to begin an 87-day jail sentence just eight days prior.
