Given the strained relationship Microsoft and Yahoo have had in recent months, it would make sense that a lot of both companies focus has gone into a potential merger rather than improving their services. Google has been able to capitalize on that, it seems, and during all the bickering has managed to thief away more of the search market, gaining 1.8% of U.S. searches. The losses other search companies weren't just relegated to Yahoo and Microsoft, though, with both them and AOL all losing.

Yahoo took the biggest dive, losing almost an entire percent. Now Google serves up 61.6% of searches, which must make Yahoo shareholders even more nervous as to where the company is going.
