The first commercially available GUI, called PARC, was developed by Xerox. It was used by the Xerox 8010 Information System, which was released in 1981.

Apple's GUI-based OS was included with the Macintosh, which was released in 1984. Microsoft released their first GUI-based OS, Windows 1.0, in 1985.
