Time for CAI to be a 50-Yr-Old Overnight Success?
PLATO @ 50: Perhaps the greatest untold story in the history of computing is the development of the PLATO system at the University of Illinois and later also at Control Data Corporation.

What is Plato?
The PLATO system was created in 1960 at the University of Illinois. Initially it ran as a one-terminal system connected to the ILLIAC computer. By 1963, the system was running on a CDC 1604 with multiple simultaneous users. By 1972, the system had expanded to run a thousand simultaneous users on a CDC CYBER mainframe. Control Data Corporation began marketing PLATO commercially in 1976, resulting in PLATO system installations in dozens of cities around the world. Many of these systems were interconnected, enabling email and remote logins through the network. For nearly ten years, there were more users on PLATO than there were on ARPANET, the precursor to the Internet.
