ComScore: Combined Microsoft and Yahoo U.S. search share stuck at 28 percent | ZDNet
The December 2010 comScore search data is out. While Microsoft is continuing to make modest gains, Microhoo is not.
Google’s U.S. explicit core search share was up slightly over November. Yahoo’s was down, and Microsoft’s also was up slightly.
(Explicit core search share removes certain categories of searches that comScore doesn’t deem to be actual “user-engaged” searches.)
