What is Bing

Bing (formerly Live Search, Windows Live Search and MSN Search), codenamed Kumo, is a web search engine and is currently the second largest search engine on the web at 16%, after its competitor Google at 60%, according to the web analytics firm StatCounter and CNBC.[1] Unveiled by Microsoft CEO Steve Ballmer on May 28, 2009 at the All Things D conference in San Diego, Bing is a replacement for Live Search; it went fully online on June 3, 2009.[2]

Notable changes include the addition of search suggestions as you type and related searches (called "Explorer pane" on the left side of search results), based on semantic technology from PowerSet[3] which Microsoft purchased in 2008.[4] Bing also includes the ability to Save & Share search histories via Windows Live SkyDrive, Facebook, and e-mail.
