Tell 32 test subjects who are going to evaluate the results that the results were from four different search engines: Google, MSN Live Search, Yahoo! and an in-house engine created for the study. Then see which ones they rate as the best. As it turns out Google and Yahoo! win hands down, proving that even on the Internet it's all about branding."
