Microsoft Bing
web search engine from Microsoft

Microsoft Bing (also known simply as Bing) is a search engine owned and operated by Microsoft, and developed by Microsoft AI. 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.

Why this record matters
“Microsoft Bing” is worth following because a concise public description often conceals a longer documentary argument. Here, Microsoft, Bing and search provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q182496. 1 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2009, 2008, 2016 and 2023.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
