Mark Zuckerberg

CATEGORY: Billionaires
COMPANY: Facebook
INDUSTRY: Technology

WHAT MAKES HIM HAUTE: The Web 2.0 wunderkind designed the perfect vessel to make social networking appeal to the increasingly addicted masses; he actually made it useful for everyone, whether young or old, hip or geeky. At 26 years old, Zuckerberg represents tech’s next generation of connected users. It also helps that in 2007, Microsoft bought a stake in the company, valuing it at $15 billion, making Zuckerberg the youngest member of Forbes’ billionaires list in 2008, although he fell below the billion mark in 2009.
