Three Keystrokes That Taught the Internet to Smile
On September 19, 1982, a Carnegie Mellon professor proposed :-) and :-( as 'joke markers' for a campus message board — and the emoticon was born.

It was 11:44 on a Monday morning when three punctuation marks changed the way the world talks.
The scene was a computer-science bulletin board at Carnegie Mellon University in Pittsburgh — an early online forum where students and professors posted messages to each other. The trouble was that nobody could hear anyone's tone of voice. Jokes were constantly being taken literally, and literal warnings were being taken as jokes. Arguments flared over misunderstandings that a single raised eyebrow would have settled in person. A running joke about lab safety had gotten so tangled that people were worried someone might take it seriously.
Scott Fahlman, a research professor at the university, decided the board needed a tool. On September 19, 1982, he posted a short proposal. It read, in full:
"I propose that the following character sequence for joke markers: :-) Read it sideways. Actually, it is probably more economical to mark things that are NOT jokes, given current trends. For this, use :-("
That was it. A colon, a hyphen, and a parenthesis, tilted sideways into a smiling face — plus its frowning counterpart. Fahlman is traditionally credited with inventing the first ASCII smiley. Similar ideas had flickered before — a Reader's Digest article in 1967 had sketched the same concept without it ever catching on — but his was the one that stuck. His own message, long thought lost, was recovered from old backup tapes in 2002, timestamp intact: September 19, 1982.
The little faces spread. From the Carnegie Mellon board they traveled to other universities, then to companies, then — as the internet grew — to the entire planet. They gave plain text something it had always lacked: a way to signal feeling. Sarcasm could be flagged. Sympathy could be conveyed. A terse message could arrive with a smile attached.
Within a couple of decades the emoticon had spawned a whole family — winks, tongues, surprised faces — and eventually the pictographic emoji, now tapped billions of times a day on phones around the world. Every yellow circle that brightens a text message descends, in a roundabout way, from one professor's attempt to stop arguments on a university bulletin board.
Nobody paid Fahlman for the idea. He never tried to claim it as property. He simply noticed a problem in how people talked to each other, typed out a solution in three characters, and let the world run with it.
The next time a :-) keeps a joke from turning into a fight, you know exactly whom to thank.
