Yes! In the past year Yahoo! has dropped Google as its primary SERP (search engine results page). Yahoo! is now working with its own modified version of the Inktomi engine. (Inktomi is an old and respected name in the search industry).
Aside from this, MSN – with the deep pockets of Microsoft – has been gaining in popularity. In fact, MSN and Yahoo! now have more combined search traffic than Google, by about ten percent. Google has about 37% while MSN and Yahoo! combined have about 47% to 50% of the search market.
