Shortly after Netscape was released the world wide web began to draw great interest from the media and other outlets and it quickly quickly into an overnight fad among computers. Netscape was based on the original Mosaic web browser. It touted features that no other browser had at the time. Shortly after the release of Netscape Microsoft leased a copy of Mosaic and created Internet Explorer version 1.0 which was included with Windows 95 Plus Pack. As Internet Explorer was released it became available for free download around 3 months later.
While Netscape offered it's browser for free to universities and non-profits Microsoft offered it for free with every edition of Windows and was available to even commercial companies for free. New editions of both browsers were released increasingly faster in an attempt to defeat the others market share. Development was increasingly getting faster and new features were being thrown in left and right by both companies.
By the time Microsoft versions 5 and 6 came out the browser wars were drawing to a close as Microsoft cut off Netscape's air supply by including Internet Explorer with each release and by the large amount of cash it had to spare in the development of its product. By the end of 2002 Microsoft had no serious competition left and held nearly 96% of the browser market. Netscape in effect collapsed and out of it's ashes came a browser originally called Phoenix which is today known by FireFox.
Firefox continues to grow and every month they are updating their servers and seeing what things they can do to make people happy so they are always going back to Firefox. When there are problems, Firefox will try and fix it fast and they reply back to all emails sent within 24 hours.
