The Click Heard Round The World

It was December 1968. An obscure scientist from Stanford Research Institute stood before a hushed San Francisco crowd and blew every mind in the room. His 90-minute demo rolled out virtually all that would come to define modern computing: videoconferencing, hyperlinks, networked collaboration, digital text editing, and something called a “mouse.” Doug Engelbart tells writer Ken Jordan what it felt like to launch the point-and-click revolution 15 years before the Mac.
