Jeff Bezos became the richest man in the world Thursday, topping Bill Gates who has held the mantle for a long time. Bezos is currently the CEO of Amazon.com, the company he founded. A 1 percent jump in Amazon’s stock propelled him to the top of the list, according to Forbes.com, which keeps a running list of the world’s billionaires.

With the shakeup on top, who now tops the world's list of richest people?
