For the third month running Bing has grown its search engine market share at the expense of both Google and Yahoo.
The results produced by comScore show that Bing rose .2% from 15.7% in July to 15.9% in August, Google fell .4% from 66.8% to 66.4%, while Yahoo! continues to its downward spiral dropping .2% from 13% to 12.8%.

While in the minor placing’s, Ask and AOL actually increased their explicit core searches.
