Two months before Steve Jobs introduced the Macintosh to the world in 1984, Microsoft demoed an early version of Windows at COMDEX 1983. Much like the soon-to-be-announced Mac, it featured a graphical user interace with the desktop metaphor, including windows and icons. Users could open multiple windows and use Microsoft Word to edit and format a text document. Over 30 years later, Time uncovered video of this demo taken by Dan Bricklin, the co-creator of the first spreadsheet program. He carried his video camera and tape deck around the convention, and uploaded the video to YouTube two years ago. The video, beginning at 6:53, shows Microsoft Word, a clock, and an image editor all on screen at the same time.
