This historic video from 1968 is the first demonstration of most of the features of modern computing. Douglas Englebart was the head of the Augmentation Research Center (ARC) located in Stanford University’s Stanford Research Institute (SRI) in the early 1960s. Here Englebart’s team shows what they have been up too.
Their demonstration included: windows, hypertext, graphics, efficient navigation and command input, video conferencing, the computer mouse, word processing, dynamic file linking, revision control, and a collaborative real-time editor (collaborative work). All this nearly a decade before the invention of microprocessors.
