The term 'Early Web Browser' can be summarized by the crossword solution of 'MOSAIC, ' which was a web browser developed in 1993 by the National Center for Supercomputing Applications at the University of Illinois. It was the first web browser to display images, and it was the first to support inline images, sound, and video. It was also the first to support multiple windows and the first to have a graphical user interface. MOSAIC was the most popular web browser until the release of Netscape Navigator in 1994.
