Bing (formerly
Live Search,
Windows Live Search, and
MSN Search) is the current
web search engine (advertised as a "decision engine")
[2] from
Microsoft. Bing was unveiled by Microsoft CEO
Steve Ballmer on May 28, 2009 at the
All Things Digital conference in San Diego. It went fully online on June 3, 2009,
[3] with a preview version released on June 1, 2009.
Notable changes include the listing of search suggestions as queries are entered and a list of related searches (called "Explorer pane") based on
[4] semantic technology from
Powerset that Microsoft purchased in 2008.
[5] As of January 2010
[update] Bing is the third largest search engine on the web by query volume, at 3.16%, after its competitor
Google at 85.35% and
Yahoo at 6.15%, according to
Net Applications.

On July 29, 2009, Microsoft and
Yahoo! announced a deal in which Bing would power
Yahoo! Search.
