Google’s (NASDAQ: GOOG) share of the US online ad revenue market was 23.7% in Q4. That number fell from Q3, but only by .5%.
Research group IDC said that a combination of Microsoft (NASDAQ: MSFT) and Yahoo! (NASDAQ: YHOO) would have 17% of the market.
IDC was quoted as saying "It would not quite bring Microsoft-Yahoo! to where Google is in online advertising in the U. S., but it would give them a much better fighting chance than if they went it alone."
