Microsoft's revamped search engine has been a real success. Showing consistent growth since it launched in June of last year, Bing has been slowly gaining on rival Yahoo!. Now, the Microsoft search engine was overtaken Yahoo! in the U.S. search market.
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.
