Until this year's Games, the highest earning athlete was Roger Federer, with earnings of over $50 million. Even the lowest paid Olympian in the Top 20, Spanish basketball player Marc Gasol, had total earnings of over $10 million.

However, these figures were calculated before the 2012 Olympics were over, and we can be sure that they will change a lot as new athletes become famous and attract sponsorship. The advertising firm Saatchi have predicted who will be the top earners in the end, based on how popular they were with the crowds at the Games and how much positive coverage they got on social media networks. According to this method, Tom Daley will earn the most from the 2012 Olympics, followed by Jessica Ennis and Mo Farah. Andy Murray is in fourth place. Daley is far ahead of the rest though, getting over half of all mentions. You can see the Saatchi top 10 here.
