The Mac wasn't the first computer to present the user with a virtual desktop of files and folders instead of a command line and a blinking cursor. As every amateur geek historian knows, the core concepts behind the graphical user interface or GUI (including the icons, mouse, and bitmapped graphics) made their debut in 1968 in a presentation by Stanford Research Institute's Doug Engelbart celebrated as the "mother of all demos."
The revolutionary ideas in Engelbart's demo were further developed at Xerox PARC, where a 24-year-old Steve Jobs took a legendary tour in 1979 that convinced him that the GUI represented the democratic future of computing. ("I thought it was the best thing I'd ever seen in my life," he said later. "Within ten minutes, it was obvious to me that all computers would work like this someday.") He promptly licensed the GUI technology he saw at work in a non-commercial product called the Xerox Alto for a modest amount of Apple stock, and the rest is Silicon Valley history.........
