MSN/LIVE had 2nd share? I reckon this is because of the MSN being default homepage and Live being default search in IE7

James Xuan: The graph is showing percent growth, I think, not market share. (For one thing, the numbers go over 100%.)

Look at the first picture for the market share: Google 68.0%, Yahoo 18.1%, MSN/Live 9.2%, and Ask 3.9%.

interesting to compare their data with HitWise, which was just released.

It is probably best to reference all the data firms and analyze their combined stats

Yahoo! Search, MSN Search and Ask.com each received

The remaining 49 search engines in the Hitwise Search Engine Analysis Tool accounted for 1.68 percent of U.S. searches.
