The Smiley Face Emoticon’s Birthday is celebrated worldwide every September 19. This day commemorates the creation of the smiley face emoticon, which was proposed by American computer scientist Scott Fahlman on September 19, 1982. Fahlman suggested using the sequence of symbols 🙂 to distinguish jokes from serious posts on the Carnegie Mellon University computer science general board. This innovation quickly spread to networks like APRANET and Usenet, leading to the development of thousands of emoticons that convey various emotions. While emojis are widely used today, emoticons remain popular in plain text communication. People celebrate this day by acknowledging the impact of emoticons on online communication and expressing their emotions through these symbols.
