A total of 2.15 million households in the US paid USD 54.95 (euro 40.60) for the fight, which a person close said would be worth USD 45 million (euro 33.3 million) for De La Hoya and just over USD 20 million (euro 14.8 million) for Mayweather.
That person requested anonymity because the promoters did not want official figures released.
The USD 45 million (euro 33.3 million) would be the biggest purse paid to a fighter, higher than the USD 35 million (euro 25.9 million) purses Mike Tyson and Evander Holyfield reportedly were paid for their second heavyweight bout, the infamous "Bite Fight" when Tyson bit Holyfield's ear.
Mayweather beat De La Hoya on a split decision Saturday night in an entertaining fight that drew a record live gate of USD 19 million (euro 14 million) at the MGM Grand Garden arena in Las Vegas.
The American cable channel HBO produced the bout through its pay-per-view arm.
Ross Greenburg, head of HBO Sports, credited the success of the network's "24/7" reality show that ran in a coveted Sunday night slot for three weeks leading up to the fight with helping sell the bout.
Mayweather and his family, including his estranged father, Floyd Sr., and his trainer and uncle, Roger, became the stars of the show, allowing non-boxing fans a glimpse into the life of the fighter. - DDnews India
