					Bing (formerly Live Search, Windows Live Search, and MSN Search) is a 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 "Explore pane") based on[4] semantic technology from Powerset that
Microsoft purchased in 2008.[5]
On July 29, 2009, Microsoft and Yahoo! announced a deal in which Bing would power Yahoo!
Search.[6] All Yahoo! Search global customers and partners are expected to have made the
transition by early 2012.[7]
In October 2011, Bing announced it is working on new back-end search infrastructure, with the
goal of delivering faster and slightly more relevant search results for users. Known as “Tiger,”
the new index-serving technology has being incorporated into Bing globally, since August

MSN Search was a search engine by Microsoft that consisted of a search engine, index, and web
crawler. MSN Search first launched in the third quarter of 1998 and used search results from
Inktomi. In early 1999, MSN Search launched a version which displayed listings from
Looksmart blended with results from Inktomi except for a short time in 1999 when results from
AltaVista were used instead. Since then Microsoft upgraded MSN Search to provide its own
self-built search engine results, the index of which was updated weekly and sometimes daily.
The upgrade started as a beta program in November 2004, and came out of beta in February
2005. Image search was powered by a third party, Picsearch. The service also started providing
its search results to other search engine portals in an effort to better compete in the market.
 Windows Live Search
In the roll-over from MSN Search to Windows Live Search, Microsoft stopped using Picsearch
as their image search provider and started performing their own image search, fueled by their
own internal image search algorithms.[9]
 Live Search
Live Search Macros, a service for users to create their own custom search engines or use macros
created by other users, was also discontinued shortly after. On May 15, 2009, Live Product
Upload, a service which allowed merchants to upload products information onto Live Search
Products, was discontinued. The final reorganisation came as Live Search QnA was rebranded as
MSN QnA on February 18, 2009, however, it was subsequently discontinued on May 21, 2009
Microsoft recognised that there would be a brand issue as long as the word "Live" remained in
the name. As an effort to create a new identity for Microsoft's search services, Live Search was
officially replaced by Bing on June 3, 2009Yahoo! search deal
On July 29, 2009, Microsoft and Yahoo! announced that they had made a 10-year deal in which
the Yahoo! search engine would be replaced by Bing. Yahoo! will get to keep 88% of the
revenue from all search ad sales on its site for the first five years of the deal, and have the right to
sell adverts on some Microsoft sites. Yahoo! Search will still maintain its own user interface, but
will eventually feature "Powered by Bing™" brandingAll Yahoo! Search global customers and
partners are expected to be transitioned by early 2012
Market share
Before the launch of Bing, the marketshare of Microsoft web search pages (MSN and Live
search) had been small but steady. By January 2011, Experian Hitwise show that Bing's market
share had increased to 12.8% at the expense of Yahoo and Google. Bing powered searches also
continued to have a higher "success rate" compared to Google, with more users clicking on the
resulting links.[17] In the same period, comScore’s “2010 U.S. Digital Year in Review” report
showed that "Bing was the big gainer in year-over-year search activity, picking up 29% more
searches in 2010 than it did in 2009."[18] The Wall Street Journal notes the 1% jump in share
"appeared to come at the expense of rival Google Inc".[19] In February 2011 Bing beat out
Yahoo! for the first time ever in terms of search marketshare. Bing received 4.37% search share
while Yahoo! received 3.93% according to StatCounter.In March 2011, Bing-powered search
accounts for over 30% of US searches, up 5% over February. In the same period, Google fell 3%
Counting core searches only, i.e. those where the user has an intent to interact with the search
result, Bing achieved a market share of 14.54% in the second quarter of 2011 in the US
In December of 2011, Bing search queries overtook Yahoo for the first time ever. Bing's share of
searches was 15.1% in December 2011, as compared to Yahoo's, which fell to 14.5%.             Daily
