Browser wars

A browser war is a competition for dominance in the usage share of web browsers. The "first browser war" (1995–2001) occurred between proponents of Internet Explorer and Netscape Navigator, and the "second browser war" (2004–2017) between those favoring Internet Explorer, Firefox, or Google Chrome.

With the introduction of HTML5 in 2008 and CSS 3 in 2011, a new generation of browser wars began, this time considering extensive client-side scripting to the World Wide Web (WWW), and the more widespread use of smartphones and other mobile devices for web browsing. These changes have ensured that browser battles continue among enthusiasts, while the average web user is less affected.
