Hall of Fame promoter Bob Arum said over the weekend that the Manny Pacquiao-Joshua Clottey world welterweight title match held March 13 at the Cowboys Stadium in Dallas, Texas, could have generated 750,000 pay-per-view buys.

“The (final number) should be around 750,000 (buys),”said Arum, who had anticipated that the figures would somewhere be in the middle of 600,000 to 700,000.

Considering that Clottey, who is from Ghana but fights out of the Bronx in New York, has virtually no fan base to speak of, Arum was amazed by the response of the public to the fight, something that he credits to the enormous popularity and crossover appeal of the Filipino pound-for-pound king.

The biggest fight Pacquiao came against Oscar De La Hoya in December 2008 in Las Vegas with PPV subscription hitting 1.250 million and generating $70 million in revenue.

The Pacquiao-Clottey fight sold for $39.95 and based on the figures Arum released, the show should generate $35 million in sales.

Against Miguel Cotto in November last year also in Las Vegas, the PPV also hit 1.250 million buys amounting to another $70 million, making it the biggest-earning show of 2009, according to HBO, which airs the marquee fights to the public.

What also prevented the Pacquiao-Clottey event from generating more buys was the fact that the promoters had little time to promote it on a full-scale since the fight was made two months before the March 13 bout.

At present, the highest number of PPV buys recorded--2.4 million-- took place in May 2007 when De La Hoya fought Floyd Mayweather.

Other top-earners include the rematch between Mike Tyson and Evander Holyfield in 1997 that drew 1.99 million buys and Tyson’s failed challenge of the heavyweight title opposite Lennox Lewis that posted 1.97 million.

Pacquiao’s charm with the paying fans has its origins when he engaged Erik Morales in a trilogy at super-featherweight (130 lbs) that began in March 2005 and ended in November 2006.

All three fights generated a little over 1 million buys, something that was unheard of in the lower weight categories of boxing.

Aside from Pacquiao’s knockout hits with De La Hoya and Cotto, his two-round demolition of Ricky Hatton also posted impressive numbers with the subscription hitting under 1 million.
