What Was used before GUI?
The first graphical user interface was designed by Xerox Corporation's Palo Alto Research Center in the 1970s, but it was not until the 1980s and the emergence of the Apple Macintosh that graphical user interfaces became popular.developed at Xerox PARC in 1973. It was the first computer to use the desktop metaphor and mouse-driven graphical user interface (GUI).
It was not a commercial product, but several thousand units were built and were heavily used at PARC, other Xerox facilities, at least one government facility and at several universities for many years. The Alto greatly influenced the design of some personal computers in the following decades, notably the Apple Macintosh and the first Sun workstations.
