At this stage, there were essentially only two kinds of browser. One was the original development version, which was sophisticated but available only on NeXT machines. The other was the ‘line-mode’ browser, which was easy to install and run on any platform but limited in power and user-friendliness. Early in 1993, the National Center for Supercomputing Applications (NCSA) at the University of Illinois released a first version of its Mosaic browser.
