A new report from Chitika, a data analytics company for advertising, shows a correlation between an increase in Bing usage and higher versions of Internet Explorer. Put simply, it seems that more IE9 users rely on Bing as their search engine than previous versions. The strange part of this equation is that a user's browser preference is preserved as they upgrade to higher version of Internet Explorer. It doesn't seem to be the case that Microsoft is forcing users to use Bing.
