"Mayweather's junior middleweight title victory against Miguel Cotto on HBO PPV last Saturday night at the MGM Grand in Las Vegas generated a whopping 1.5 million pay-per-view buys and $94 million in domestic pay-per-view revenue, HBO Sports announced Friday.
The performance ranks as the second-highest grossing pay-per-view for a non-heavyweight fight in history. No. 1 all-time remains Mayweather's 2007 victory against Oscar De La Hoya, in which he also claimed a junior middleweight belt.
In nine HBO PPV main events, Mayweather has generated 9.6 million buys and $543 million in television revenue, according to HBO."
