New search data puts Microsoft at an 11.5% share, up 3% since the launch of Bing. Much of this comes from Yahoo, which is down nearly 3% since the launch of Bing. Google has seen little movement, gaining 0.5%. Microsoft has been trying to catch Google in the search market for a long time, and should continue to see gains as it will be receiving much of the searches from Yahoo due to an agreement between the two companies. It would probably be a good thing for Google if Microsoft continued to gain, as it may help to get anti-trust regulators off its back.
