Nielsen reports that last month, Bing overtook Yahoo! for the first time, with a search market share of 13.9 percent to Yahoo!'s 13.1 percent. Though it's definitely a win for Microsoft, we don’t imagine Yahoo! will be too upset. CEO Carol Bartz has said in the past that Yahoo! is not a search company and more recently, the company signed a deal with Microsoft that involves Microsoft technology powering Yahoo! search. Reuters reports that if you combine Bing-powered search, Microsoft accounts for 26 percent of the search market.
Google continues to lead with 65 percent of the U.S. search market.
But most people are used to Google so it would be tough for Bing to beat Google. If anything it will suck away some Googlers.
I sure hope this doesn't end up like IBM and NetScape.
