To provide a little context, Googles revenue in the UK alone was $200 million more than Facebook's highest revenue reports ($500 million). http://investor.google.com/releases/2009Q3_google_earnings.html http://investor.google.com/releases/2009Q3_google_earnings.h... On earnings calls, every quarter, the report on revenue growth is centered around various metrics with search advertising. Search advertising continues to be the most profitable form of advertising on the web. Facebook has impressive statistics, but I don't see them challenging Google in any one of Google's core businesses. When Facebook becomes a public company and matures more and has a solid way of generating revenue then they might be in a position to challenge Google.
