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.
Bing revealed a new logo on September 17, 2013, it was rolled out in the following weeks. It was still used on the website for a short time after the 2016 logo was introduced.
This icon for this logo is still shown when you search, and on some other pages.
A different new Bing logo was launched on January 14th 2016. Used in tandem with the previous logo until February 2016. It looks the same with different colors, the lowercase b was changed to a capital B and the b in the symbol was modified slightly.
Still used on some portals.
