Douglas Engelbart’s demonstration of 1968, popularly referred to as the “mother of all demos”, was a milestone in the history of computers. It belonged to the category of “mid-century innovations” and is significant for introducing the fundamental concepts that characterized the modern computer. Engelbart and his team at SRI introduced the very first computer mouse, which revolutionized the way humans interacted with computers. The demonstration also featured windows, hypertext, and real-time text editing, all of which went on to influence operating systems. They also showed a very early form of hypertext navigation, which went on to become the basis for the World Wide Web. Engelbart’s system, which could handle multiple users at the same time editing documents, was a precursor to software like Google Docs. Engelbart’s demonstrations were far ahead of their time and laid the foundations for personal computers, Internet construction, and interactive technology.
