During the 1960s, Douglas Engelbart and the Augmentation Research Center at Stanford Research Institute developed the oN-Line System (NLS), a comprehensive computing platform built on Engelbart's vision of using computers to augment human intellect. Years of research produced working implementations of technologies then unknown outside specialized labs.
On December 9, 1968, Engelbart delivered a 90-minute live demonstration at the ACM/IEEE Fall Joint Computer Conference in San Francisco, publicly presenting for the first time a unified system featuring windows, hypertext, graphics, the computer mouse, word processing, video conferencing, dynamic file linking, revision control, and a collaborative real-time editor.
The demonstration proved enormously influential, directly inspiring projects at Xerox PARC in the early 1970s. The concepts and technologies it introduced shaped the graphical user interfaces of the Apple Macintosh, Atari ST, Commodore Amiga, Acorn Archimedes, and Microsoft Windows in the following decades.
