View source for 14. How did the browser evolve since it was first invented?

	The turning point for the World Wide Web was the introduction[4] of the Mosaic web browser[5] in 1993, a graphical browser developed by a team at the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign (UIUC), led by Marc Andreessen. Funding for Mosaic came from the High-Performance Computing and Communications Initiative, a funding program initiated by then-Senator Al Gore's High Performance Computing and Communication Act of 1991 also known as the Gore Bill.[6]
	The origins of Mosaic had begun in 1992. In November 1992, the NCSA at the University of Illinois (UIUC) established a website. In December 1992, Andreessen and Eric Bina, students attending UIUC and working at the NCSA, began work on Mosaic. They released an X Window browser in February 1993. It gained popularity due to its strong support of integrated multimedia, and the authors’ rapid response to user bug reports and recommendations for new features.
	After graduation from UIUC, Andreessen and James H. Clark, former CEO of Silicon Graphics, met and formed Mosaic Communications Corporation to develop the Mosaic browser commercially. The company changed its name to Netscape in April 1994, and the browser was developed further as Netscape Navigator.

	Microsoft, which had thus far not marketed a browser (in fact even as late as 1995 Bill Gates dismissed personal use of the World Wide Web as a passing fad)[citation needed], finally entered the fray with its Internet Explorer product, purchased from Spyglass, Inc. This began what is known as the browser wars, the fight for the Web browser market between Microsoft and Netscape.
	The wars put the Web in the hands of millions of ordinary PC users, but showed how commercialization of the Web could stymie standards efforts. Both Microsoft and Netscape liberally incorporated proprietary extensions to HTML in their products, and tried to gain an edge by product differentiation, leading to the acceptance of the Cascading Style Sheets proposed by Håkon Wium Lie over Netscape's JavaScript Style Sheets (JSSS) by W3C.
