Unlike the original browser, WorldWideWeb on NeXT, Mosaic was available for the Microsoft Windows platform and added features such as inline graphics viewing. It was developed by the National Center for Supercomputing Applications at the University of Illinois at Urbana–Champaign. NCSA Mosaic was distributed freely for non commercial use, but required a license for commercial business use. It was licensed by a number of third party OEMs, including Microsoft, who used it for the basis of Microsoft Internet Explorer. In 1995, its popularly quickly gave way to Netscape Navigator.
