Yahoo finished the transfer of its web and mobile search functions to Microsoft’s latest Bing search engine with the hope that the two companies will use their combined market power may to pose a more significantly big threat to the Google domination in the web world.

This integration is being done more than a year after Yahoo and Microsoft had declared their a decade’s contract of a search deal under which Microsoft will be powering Yahoo’s search site, while Yahoo will keep managing the sales of both the companies’ advertisers of premium search.

In a statement in a blog post, the senior vice president of Microsoft’s online services division, Mr. Satya Nadella said that this merger between Yahoo and Bing is a big milestone for both the companies, and that the transition has worked out so smoothly is a happy occasion indeed and everybody is feeling great about the kind of development their search alliance has been making over the summer.

Yahoo and Microsoft together have a 28 percent share in the US search market, as compared to Google’s 66 percent. Yahoo expects to save the high development cost of its own cutting edge search technology through this deal.
