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.
