Pound-for-pound king Manny Pacquiao’s lopsided decision victory against Shane Mosley on May 7 generated more than 1.3 million pay-per-view buys — Pacquiao’s best box office performance yet — Top Rank promoter Bob Arum told ESPN.com.

Pacquiao’s previous best pay-per-view total was the 1.25 million generated by his eighth-round knockout of Oscar De La Hoya in a big upset in December 2008. Four of Pacquiao’s last six fights — Mosley, De La Hoya, Antonio Margarito and Miguel Cotto — have topped 1 million buys.

The total was the second-best pay-per-view performance for Mosley, whose lopsided loss to Floyd Mayweather Jr. in May 2010 sold 1.4 million units.

Arum said Pacquiao-Mosley generated more than $75 million in television revenue with about 700,000 buys coming via cable systems and about 600,000 coming from satellite services.

Pacquiao retained his title in the fight, which took place at the MGM Grand in Las Vegas and generated a live gate of $8,882,600, the 14th-highest gross in Nevada history from 15,422 tickets sold.

All of Pacquiao’s and Mosley’s previous significant pay-per-view fights had been handled by HBO PPV. However, Arum made a deal for this fight with Showtime PPV in exchange for wide exposure of the bout on sister network CBS.

The reason Arum gave for the lag in getting pay-per-view numbers and for why he is unsure of more precise totals is because Showtime, largely out of the pay-per-view business in recent years, does not have the kind of database and expertise to extrapolate numbers like HBO does.
