Six billionaires who made their fortune through the Facebook website enjoyed significant increases in their wealth, according to the latest Forbes rich list.
The social networking sites founder and CEO, Mark Zuckerberg, now ranks 52nd on the annual list, with an estimated fortune of around $13.5m.
Co-founder Dustin Moskovitz, Sean Parker, Peter Thiel, Yuri Milner, and Eduardo Saverin also have Facebook to thank for their appearances on the list.
Moskovitz replaces Zuckerberg as the world's youngest billionaire at 26 years old. His fortune stands at $2.7bn.
The increased wealth of the six follows a $1.5bn capital injection by Goldman Sachs into Facebook. The company is currently valued at around $50bn.
Mexican tycoon Carlos Slim Hélu remains top of the Forbes list with a fortune of $74bn, with Bill Gates and Warren Buffett in second and third position.
