Microsoft Corp has sealed agreements to access real-time content on hot social networking sites Facebook and Twitter, a boost for its fledgling Bing search engine.

Bing, which hopes to take on current dominant search leader Google Inc , will have access to Twitter's entire store of public data in real time, Microsoft executives said at a presentation at a San Francisco Internet conference.

The terms of the deals -- which the executive said were non-exclusive -- were not disclosed.
