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. Bing offers a broad spectrum of search services, encompassing web, video, image, and map search products, all developed using ASP.NET.

The transition from Live Search to Bing was announced by Microsoft CEO Steve Ballmer on May 28, 2009, at the All Things Digital conference in San Diego, California. The official release followed on June 3, 2009. Bing introduced several notable features at its inception, such as search suggestions during query input and a list of related searches, known as the 'Explore pane'. These features leveraged semantic technology from Powerset, a company Microsoft acquired in 2008. Microsoft also struck a deal with Yahoo! that led to Bing powering Yahoo! Search.

Microsoft made significant strides towards open-source technology in 2016, making the BitFunnel search engine indexing algorithm and various components of Bing open source. In February 2023, Microsoft launched Bing Chat (later renamed Microsoft Copilot), an artificial intelligence chatbot experience based on GPT-4, integrated directly into the search engine. This was well-received, with Bing reaching 100 million active users by the following month.

As of 2023, Bing holds the position of the second-largest search engine worldwide, commanding a query volume of 12%, trailing Google's 79%. Other competitors include Baidu with 5% and Yahoo! Search, which is largely powered by Bing, with 2%.
