March was an interesting month for the search market, according to new statistics from comScore. Not so interesting that Google isn't still on top by a huge margin, of course, but interesting insofar as the search giant lost a bit of market share, even as Bing and Yahoo improved their standing. Let's start with Google's story. In February, comScore puts its market share at 65.5 percent. That declined to 65.1 percent in March, which is a moderately unusual turn of events.
