From the NY Times:
Facebook Raises $16 Billion in I.P.O. That Values It at $104 Billion
As investors raced to get shares, whose price Facebook set at $38 each, the sprawling social network raised $16 billion on Thursday in an initial public offering.
The I.P.O. signals a rapid evolution for the company. In just eight years, Facebook has gone from a scrappy college service founded in a Harvard dormitory to the third-largest public offering in the history of the United States, behind General Motors and Visa.
