U.S. and European Union regulators gave the ok last week to their online search deal allow the two to combine much of their search business. This starts a 10 year deal in which search results on Yahoo will state they are powered by Bing. Microsoft will give Yahoo 88% of revenue it receives from Yahoo searches as well as have access to Yahoo’s search technology for integration purposes although I am not sure why they would want to.
In my opinion, Yahoo’s search relevancy has plummeted in the recent years giving up massive market share to Google. Although still a relatively small player in search, Bing could potentially make a huge leap if their decision engine concept catches on.
