The pay-per-view (PPV) numbers for the Floyd Mayweather Jr. and Manny Pacquiao bout last May 2 officially shattered past records as it sold 4.4 million PPV units and raked in about $400 million in revenue.

Yahoo Sports noted that the Las Vegas fight of the two well-known boxers was definitely a grand slam.

"The old mark for sales was 2.48 million, set May 5, 2007, when Mayweather defeated Oscar De La Hoya in Las Vegas. The former revenue record was $150 million, established by Mayweather in 2013 in a fight with Canelo Alvarez at the MGM Grand that sold 2.2 million pay-per-views," explained Yahoo Sports.

The live paid gate for the fight reportedly hit $71 million, a far cry from the Mayweather-Alvarez record which was at $20 million.

Business Insider discussed that the overall revenue of the fight could fall to $500 million as estimated by HBO and Showtime. Considering money that came in from ticket sales, international broadcast sales, closed-circuit broadcasts in bars, sponsorships and merchandise, the same report explained that the total revenue of the fight could "be between $550 and $595 million depending on exactly how many of the PPV buys were in HD ($100) versus SD ($90)."

From this total earning, about $350 million will reportedly go to the pockets of the two fighters with Business Insider saying that the undefeated American fighter can take home more than 200 million while Pacquaio will get more than $140 million.

"It is hard to imagine that anybody would turn down a rematch, even if the hype can't approach these same levels. This revenue at half the rate is still pretty decent for a day's work," added Business Insider.

In an interview with Yahoo Sports, Mayweather Promotions CEO Leonard Ellerbe said the high PPV numbers only reveal that Mayweather has a great star power. He also acknowledged the power of social media which helped in marketing the fight around the world.

"The world is different now thanks to social media and the way you can market these events. Social media and the incredible amount of media coverage we had in the build-up to this fight played a huge role in all of this. My team always sets the bar high, and our goal was to break the previous record, and we just kept pushing the envelope," Ellerbe added.

It will be interesting how the public will react if a sequel of this matchup will be pushed, considering the not-so-good performance of the two fighters on the ring.
