Just like that, the universe of web search engines has collapsed into itself a little more. Yahoo announced on its official Search Blog yesterday that the "transition of organic search between Yahoo! and Microsoft is complete." In other words, Yahoo’s web, image, and video searches in the U.S. and Canada are now going through Microsoft’s Bing platform.
On its end, Microsoft says the next step is now Yahoo’s migration to adCenter advertising services. The two companies expect to complete this step "later this fall." Both firms are, of course, super-excited about the transition, judging by the wording of their blog posts. Why wouldn’t they be? The partnership should allow Yahoo to forgo sinking millions of dollars into its own search engine technology, while Microsoft will be able to broaden its search market share.
Searching on Yahoo right now indeed brings up pages with a little "Powered by Bing" mention at the bottom. Results appear to be slightly different between the two portals, though. The first six matches for "The Tech Report" are the same on Bing and Yahoo, but subsequent matches differ, with the former bringing up our price search engine and the latter a college football story.
