New Internet search partners Yahoo Inc. and Microsoft Corp. left a small dent in Google Inc.'s market dominance last month. Google ended August with a 65.4 percent share of the U.S. search market, down from 65.8 percent, based on an analysis by the research firm comScore Inc.
The share that Google lost in August went to Yahoo and Microsoft, which are teaming up in an attempt to pose a more formidable challenge to Google. Yahoo's website in the U.S. switched over to Microsoft's search technology in late August as part of a partnership that is supposed to last for the next decade.
Yahoo ranked second with U.S. search share of 17.4 percent last month, up from 17.1 percent in July. Microsoft's Bing processed 11.1 percent of U.S. searches in August, up from 11 percent in July.
