GUI (pronounced “gooey”) uses a computer’s processing capabilities to display information. But it was ultimately Apple and Microsoft who reaped the benefits, and brought GUI to the masses. GUI was pioneered by computer engineers at the Xerox Palo Alto Research Center (aka. And it features no shortage of corporate skullduggery and missed opportunities. The origin story of GUI dates back to the 1970s. Indeed, it’s one of the major reasons we spend so much time on our devices today. And if you made a spelling mistake, well sir, you’d need to re-type it. You had to know the correct thing to write.

To do anything, you’d type text commands into a command-line interface. Although much of The Mac OS is original, it was similar enough to the old Alto GUI to make a 'look and feel' suit against Microsoft dubious.Before Graphical User Interface (GUI) came along, using a personal computer was outrageously clunky. The fact that both Apple and Microsoft had gotten the idea of the GUI from Xerox put a major dent in Apple's lawsuit against Microsoft over the GUI several years later. 'Hey that's no fair! I wanted to steal the TV set!

No, Steve, I think its more like we both have a rich neighbor named Xerox, and you broke in to steal the TV set, and you found out I'd been there first, and you said. When Jobs accused Bill Gates of Microsoft of stealing the GUI from Apple and using it in Windows 1.0, Gates fired back:

Although much of the Interface of both the Lisa and the Mac was based (at least intellectually) heavily on the work done at PARC, and many of the engineers there later left to join Apple, much of the Mac OS was written before Job's visit to PARC. Jobs took a tour of PARC in 1979, and saw the future of personal computing in the Alto. The Alto was the size of a large desk, and Xerox believed it unmarketable. The GUI had its roots in the 1950s but was not developed until the 1970s when a group at the Xerox Palo Alto Research Center (PARC) developed the Alto, a GUI-based computer.
