Title

Public Demonstration of Online Systems and Personal Computing, 1968

Citation

Commonly termed the "Mother of All Demos," Douglas Engelbart and his team demonstrated their oNLine System (NLS) at Brooks Hall in San Francisco on 9 December 1968. Connected via microwave link to the host computer and other remote users at SRI in Menlo Park, the demonstration showcased many fundamental technologies that would become ubiquitous, including collaborative online editing, hypertext, video conferencing, word processing, spell checking, revision control, and the mouse.

Historical significance of the work

Helping catalyze a fundamental switch in the way computers are used, i.e. as communication and knowledge navigation devices rather than primarily for calculation. A variety of technologies were shown in this demo that made their way into later computing systems - video conferencing, hypertext, collaborative editing, mice, GUIs, etc. Many of these would go on to influence the Xerox PARC Alto and later the Macintosh and Windows operating systems.

The phrase "Mother of All Demos" has entered the vernacular in reference to this event, and especially when used in the computing community, is recognized as referring to this event. "Demo" in this case being short for "demonstration" (as opposed to "demolition," which it can mean in civil engineering or architectural contexts).

The practical obstacles were getting funding for such radical ideas, assembling the world-class hardware and software engineers needed to make them a reality, and developing the actual software and hardware given that most of the main elements needed to be invented or at developed from scratch. The main obstacle, however, was one of attitude: the mainstream computer science community and industry of the era did not see communication and knowledge navigation as a practical or cost-effective application for computers

Features that set this work apart from similar achievements

It's difficult to think of any comparable achievements; this short demo gave a (working) glimpse of the major end-user computing technologies of the next twenty-five-plus years.
