Englebart also demoed how documents could be linked together using what we know today as hypertext linking. He show video conferencing by overlaying a computer screen with a TV image and explained how the Augmented Human Intellect (AHI) Research Center would be working with ARPA on a network that later became the internet. Engelbart said such a network would need to provider a way for users to “see” what services were available. This idea is very much how internet-based services and web services work today.
It was described by as the mother of all demos. On December 9th 1968 Doug Engelbart and a group of researchers from the Augmented Human Intellect (AHI) Research Center at Stanford Research Institute gave a public demonstration of how they saw IT would change the way people work.
The 90 minute demo to 1000 computer professional was the first public showing of a mouse, hypertext linking and significantly the concept of personal computing.
