NEW YORK -- He famously wears a hoodie, jeans and sneakers, and he was born the year Apple introduced the Macintosh. But Mark Zuckerberg is no boy-CEO.

Facebook's chief executive turned 28 on Monday, setting in motion the social network's biggest week ever. The company is expected to start selling stock to the public for the first time and begin trading on the Nasdaq Stock Market on Friday. The IPO could value Facebook at nearly $100 billion, making it worth more than such iconic companies as Disney, Ford and Kraft Foods.
