$25,000 given to U.S. athletes by USOCSilver medal:
Neither the International nor the U.S. Olympic Committees pay the athletes for competing, but the USOC pays athletes a good sum for winning medals.
But the real money that athletes make comes from lucrative marketing deals. U.S. swimmer Michael Phelps, for instance, receives an estimated $5 million for plugging companies like Omega, PowerBar, Visa and Speedo.
Phelps will also get a $1 million bonus from Speedo if he can match the record seven golds in a single Olympic Games set by U.S. swimmer Mark Spitz in the 1972 Summer Games in Munich, Germany. NEXT: Ticket sales
