Microsoft announced a broad range of new functionality for Bing, its search engine, on Nov. 11. In addition to incorporating results from Wolfram Alpha, a "computational engine" that provides a definitive numerical answer to a search query, the revamped Bing offers a more robust video page—with feeds from MSN Video, Hulu, and ABC—and more intensive search in categories such as local events and cities.
In a sign of the increased importance of social networking to corporations such as Microsoft and Google, Bing has also incorporated Facebook and Twitter into its search features.
