What Are Three Things Doug Engelbart Invented?

In 1968, Douglas Englebart gave a demonstration at a computer conference in San Francisco of concepts he and his small group at the Stanford Research Institute were developing. Included were a point-and-click tool called a mouse, text editing, video conferencing, hypertext and windowing.

Computers at that time were standalone mainframes that were fed programs by punched cards. Dr. Englebart's Online System was the first to show information that could be clicked, moved or copied using a handheld pointer. That pointer, called a mouse, was an idea he started making notes on in 1961, with the first model, made of wood, being built in 1964. His group's networked computers were part of the early ARPANET, a progenitor of the current Internet.
