In 2004, Mark Zuckerberg created Facebook in his dorm room, not knowing that 10 years later he would be a billionaire with a billion people suing the social network. Oh, he's also turning 30.
In 2007, he was routinely dismissed as a real threat to the tech establishment, according to Forbes. In fact, the business magazine wrote:
Rumors swirling around Silicon Valley suggest Zuckerberg’s widely popular online social networking site Facebook could fetch more than $10 billion. That seems too high to us. The company has only $150 million or thereabouts in annual revenues. Sure it’s growing fast. But for the company to be worth $4.3 billion–making Zuckerberg’s estimated 30% stake worth the $1.3 billion price of admission for this year’s Forbes 400–Facebook would need to sell for nearly 30 times sales.
U.S. & World
Forbes was wrong and Facebook did very well indeed. While there's no guarantee Facebook will continue to grow or be profitable -- after only 10 years, Zuckerberg took something from nothing to a $153 billion market cap. In terms others will understand: Microsoft's Bill Gates hadn't launched Microsoft Windows at 30; Steve Jobs was kicked out of Apple at 30; and at 30, Amazon's Jeff Bezos was just starting up the e-commerce site.
