The events Before the Browser Wars began when the Internet became available to a public audience in the early 1990s when CERN employees launched the WorldWideWeb browser, (later renamed to Nexus). That action kick-started the creation of other web browsers, most of which didn't last long in the market. However, Mosaic (a browser launched in January 1993) gained enough market share to provide enough momentum for the Browser Wars, not by involving itself in it as a competitor, but by having a spin-off browser by the name of Netscape spawn off of Mosaic's success and dominate the market where Mosaic left off. As Mosaic left the market, Internet Explorer (IE) entered as a challenger to Netscape's crown, and thus the first browser war began.
