Which company launched the Internet Explorer browser?

Microsoft launched the Internet Explorer browser.

Internet Explorer was developed by Microsoft and first released on August 24, 1995, as part of the Microsoft Plus! add-on package for Windows 95. It was designed during the early commercial growth of the World Wide Web, when browsers were becoming an important part of personal computing.

The first version was based on technology licensed from Spyglass, whose browser was derived from the earlier NCSA Mosaic project. Microsoft then expanded Internet Explorer rapidly, adding support for features such as cookies, SSL, frames, JavaScript-related scripting, and later tabbed browsing. The browser became closely integrated with Windows.

That integration helped Microsoft overtake Netscape Navigator during the first browser war. Internet Explorer reached roughly 95 percent usage share around 2002–2003, but later lost ground to Firefox, Chrome, and mobile browsers. Microsoft Edge succeeded it as Microsoft’s primary browser, and Internet Explorer 11 support ended for most Windows 10 users on June 15, 2022.
