Microsoft introduced a new version of Bing Thursday representing the biggest overhaul to the search engine since its launch. The changes emphasize closer ties with Facebook by integrating the expertise of friends from the social site, as well as LinkedIn, Twitter, and Quora. The company will mine online social connections to provide more personal search results for everything from movie recommendations to restaurants. The engine will support a three-column design combining traditional Web search and social. Advertisers can expect to see new ad models emerge from this design.
