Windows Live Search
The first public beta of Windows Live Search was unveiled on March 8, 2006, with the final release on September 11, 2006, replacing MSN Search.
On March 21, 2007, Microsoft announced that it would separate its search developments from the Windows Live services family, rebranding the service as Live Search.
In 2008, 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, 2009.
Brand New ranked this the worst logo of 2009.
