Bing (formerly Live Search, Windows Live Search, and MSN Search) is the current web search engine (advertised as a "decision engine") from Microsoft. Unveiled by Microsoft CEO Steve Ballmer on May 28, 2009 at the All Things Digital conference in San Diego, Bing is a replacement for Live Search. It went fully online on June 3, 2009, with a preview version released on June 1, 2009. By August 2009, Bing had gained 9.3 percent of the United States Internet search market. However, by September, StatCounter stated that Bing's share of the US search market in September had fallen by over one percentage point to 8.51%. Comscore claimed otherwise, stating that Bing's growth had held steady in September 2009, gaining 0.1 percent of the total United States Internet Search Market representing a market share of 9.4 percent.
