This competition gave birth to Netscape web browser, which became the dominant software of its kind for several years. So the main competition under Windows at that time was among several versions of Mosaic and Cello. But Microsoft did not seem to recognize the importance of the web browser then. Microsoft Windows was the fastest growing major platform for PC in the first half of 1990s. Mosaic was not the first web browser for Windows though and it could not supersede Cello, the first and initially the only web browser for Windows.

First for Unix and then for Apple Macintosh and Microsoft Windows. The turning point for the World Wide Web and all Internet was the advent of Mosaic, a graphical web browser, in 1993. The rest of users might expect more likely only a text-mode interface experience through a text-based web browsers like Line Mode Browser. The first web browser ever, WorldWideWeb (later renamed Nexus) had many of the features later to be considered as standard for web browsers, but it was an experiment, accessible and known to very few. As to general public, it all very much revolves around the web browser. World Wide Web service with its online experience like hypertext links, surfing, web pages as a combination of text and images / multimedia brought Internet to general public.
