The highly anticipated fight between Floyd Mayweather Jr. and Manny Pacquiao may not have lived up to the expectations brought about by its billing as the "Fight of the Century," but it certainly delivered when it was pegged as the richest fight in the history of the sport.

As reported by Yahoo Sports, officials announced that the fight held at the MGM Grand Garden Arena in Las Vegas last May 2 sold 4.4 million pay-per-view units, which translated to over $400 million in revenue. That number nearly doubled the previous record of 2.48 million buys generated by the 2007 fight between Mayweather and Oscar De La Hoya. The previous record for revenue was $150 million, which also involved Mayweather when he beat Canelo Alvarez back in 2013. That fight sold 2.2 million pay-per-view units. The Mayweather-Pacquiao bout also smashed the live paid gate record. The May 2 fight got $71 million at the gate, obliterating the previous high of $20 million.

"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 envelop," Mayweather Promotions CEO Leonard Ellerbe said.

As noted by Kevin Iole of Yahoo Sports, Facebook reported that on the night of the fight, some 37 million unique users made 115 million posts about the fight from a period that began before the event's start until half an hour after it ended.

"I can't thank Floyd enough for making this all happen and it goes back to when he approached Manny in Miami that put the icing on the cake," said Ellerbe.
