Facebook's IPO goes live at Nasdaq

Facebook's stock is set to begin trading on the Nasdaq Stock Market on Friday, the day after the world's definitive online social network raised $16 billion in an initial public offering that valued the company at $104 billion. That's more than Amazon.com and other well-known companies such as Kraft, Walt Disney and McDonald's.

The site, which was born in a dorm room eight years ago and has grown into a worldwide network of almost a billion people, is making the most talked-about stock market debut in years.
