Pittsburgh ? It was a serious contribution to the electronic lexicon.

🙂

Twenty-five years ago, Carnegie Mellon University professor Scott E. Fahlman says, he was the first to use three keystrokes – a colon followed by a hyphen and a parenthesis – as a horizontal “smiley face” in a computer message.

To mark the anniversary today, Fahlman and his colleagues are starting an annual student contest for innovation in technology-assisted, person-to-person communication. The Smiley Award, sponsored by Yahoo Inc., carries a $500 cash prize.

Language experts say the smiley face and other emotional icons, known as emoticons, have given people a concise way in e-mail and other electronic messages of expressing sentiments that otherwise would be difficult to detect.
