Summary:
Plato was an online and interactive learning computer system developed in the 1960s at the University of Illinois. But in the early 1970s, Plato got truly networked, and the users took over. Plato had already pioneered such things as touch screen computing, but the kids introduced and pioneered concepts like forums, message boards, e-mail, chat rooms, instant messaging, multiplayer games and even emoticons/emojis were pioneered on the Plato system.
