The browser that opened the web

Shut down
19902026

Netscape Navigator was the browser that took the web mainstream, released on 15 December 1994, holding roughly 80% of the market at its mid-90s peak. Microsoft bundled Internet Explorer with Windows and destroyed its business; AOL bought the remains in 1999 and ended all support on 1 March 2008.

Why it shut down

Official line: AOL: "Given AOL's current business focus and the success the Mozilla Foundation has had... we feel it's the right time to end development of Netscape-branded browsers" — support ended 1 March 2008.

Our analysis: Netscape lost the browser war to a free competitor bundled with the operating system. The antitrust case against Microsoft came too late to save it, but the 1998 decision to open-source the code created Mozilla, and through it Firefox: the real successor.

History

The web goes mainstream

Marc Andreessen and Jim Clark founded Mosaic Communications in 1994, shipped Navigator 1.0 on 15 December, and put the web on ordinary desktops. Its August 1995 IPO, with the stock doubling on day one before the company had meaningful profits, is the conventional starting gun of the dot-com boom. Through the mid-90s Navigator was the web for most users, with an estimated four-fifths of the browser market.

The browser war

Microsoft licensed Mosaic code, shipped Internet Explorer free, and from Windows 98 onward welded it into the operating system. Netscape could not sell what Microsoft gave away; the US antitrust case (United States v. Microsoft) documented the strangulation in detail but arrived too late. In January 1998 Netscape open-sourced the browser as Mozilla, and in November 1998 AOL announced a stock acquisition valued around $4.2 billion (roughly $10 billion by closing in March 1999). AOL kept the brand on life support for a decade before ending support on 1 March 2008, politely directing the last users to Firefox: the browser Netscape's own liberated source code had become.
