Microsoft Bing, commonly referred to as Bing, is a search engine owned and operated by Microsoft. The service traces its roots back to Microsoft's earlier search engines, including MSN Search, Windows Live Search, and Live Search.

Why is it called Bing? The search engine was given its name after being chosen through focus groups, with Microsoft settling on the name as it would remind people of the sound made at 'the moment of discovery and decision making.

Bing is a Microsoft-owned alternative to Google, and thus can be used in any web browser or as an app on your smartphone. You can also set Bing as the default search engine in Chrome, Firefox, or Safari if you wish; if you use Microsoft Edge or Internet Explorer, Bing is the search engine by default.
