The GUI Revolution! Starting with the Xerox Star, engineers developed a more intuitive way of interacting with a computer than the archaic command line of operating systems such as CP/M or PC-DOS. What they developed was the GUI, among other things, and it was refined and released by Apple with the Lisa. Unfortunately, the Lisa didn't sell well because of it's price and the first truly successful computer built around a graphical interface was the Apple Macintosh. It, like the Amiga and the Atari ST series, was released years before Microsoft Windows became popular. In fact, there were even other GUI environments for IBM PC's and clones, such as GEM from Digital Research, which went on to provide the basis for the TOS operating system Atari used in the ST.
