From the New York Times:
Netscape Navigator, the world’s first commercial Web browser and the starting point of the Internet boom, will be pulled off life support Feb. 1 after a 13-year run.
Its current caretakers, Time Warner’s AOL, decided to end further development and technical support to focus on developing the company as an advertising business. Netscape’s use dwindled with Microsoft’s entry into the browser business in the 1990s, and Netscape all but faded away after the birth of its open-source cousin, Firefox.
