In light of Carol Bartz’ exit from Yahoo!, here’s a brief look at ad revenues at the top five ad-selling companies:

Google’s projected $16.53 billion net US ad revenues in 2012 will be about 60% greater than the other four companies combined. Those deep financial reserves, which Google is using to expand its display and mobile ad offerings, suggest how the “Google vs. Facebook” war that’s often hyped in the media is still not much of a contest.
