Douglas C. Engelbart publicly demonstrates the mouse
9th December 1968
It is a device that he had been thinking about and working on for more than a decade.
He also demonstrated video conferencing and hypermedia. Those "inventions" weren't designed to make money or create a product. Rather, they were part of Engelbart's desire to "find much better ways for people to work together to make this world a better place."
During that landmark demonstration Douglas C. Engelbart, of the Stanford Research Institute, demonstrates his system of keyboard, keypad, mouse and windows at the Joint Computer Conference in San Francisco's Civic Center.
He demonstrates the use of a word processor, a hypertext system, and remote collaborative work (later coined as: "teleworking") with colleagues.
