1982 – Scott Fahlman posts the first documented emoticons 🙂 and 🙁 on the Carnegie Mellon University bulletin board system.
Scott Fahlman was the first documented person to use the emoticons 🙂 and :-(, with a specific suggestion that they be used to express emotion. The text of his original proposal, posted to the Carnegie Mellon University computer science general board on 19 September 1982 (11:44), was thought to have been lost, but was recovered 20 years later by Jeff Baird from old backup tapes.
