After months of pressure, social media giant Facebook is going public.  But for those itching to get their hands on a piece of the Facebook pie, there will be a wait.

FOX News Radio's Lisa Brady has more:

After months of speculation, Facebook files the paperwork for its initial public offering - likely to hit the stock market three or four months from now, and suggesting it hopes to raise $5 billion.  Google raised $1.9 billion in its 2004 IPO.

The 27-year-old CEO of Facebook, Mark Zuckerberg, already worth a fortune - more than $17 billion in a Forbes Magazine estimate just eight years after launching the service at Harvard.  The big mystery now: the market value of Facebook, which analysts think could hit $100 billion.
