Web browser a web browser installed. The most popular web browsers are Chrome, Firefox, Safari, Internet Explorer, and Edge. The first web browser, called WorldWideWeb, was invented in 1990 by Sir Tim Berners-Lee. He then recruited Nicola Pellow to write the Line Mode Browser, which displayed web pages on dumb terminals; it was released in 1991. 1993 was a landmark year with the release of Mosaic, credited as "the world's first popular browser". Its innovative graphical interface made the World Wide Web system easy to use and thus more accessible to the average person. This, in turn, sparked the Internet boom of
Embrace, extend, and extinguish extensions. For example, in 1995, Netscape implemented the "font" tag, among other HTML extensions, without seeking review from a standards body. With the rise of Internet Explorer, the two companies became locked in a dead heat to out-implement each other with non-standards-compliant features. In 2004, to prevent a repeat of the "browser wars", and the resulting morass of conflicting standards, the browser vendors Apple Inc. (Safari), Mozilla Foundation (Firefox), Google Inc. (Google Chrome) and Opera Software (Opera browser) formed the Web Hypertext Application Technology Working Group (WHATWG) to create open standards to complement those of the World Wide Web Consortium.
