In 1982, a physics joke gone wrong sparked the invention of the emoticon
A simple proposal on a 1982 electronic bulletin board helped sarcasm flourish online.

TL;DR
- Scott Fahlman proposed the use of :-) and :-( as markers for jokes and serious comments on September 19, 1982.
- The proposal originated from a discussion on Carnegie Mellon's bulletin board software after a misunderstood joke led to confusion.
- Neil Swartz initially suggested using an asterisk (*) to mark jokes, followed by other suggestions from colleagues.
- Fahlman's proposal combined simplicity, visual clarity, and a binary system for humor and seriousness.
- The limited character set of early computer terminals made text-based solutions like emoticons necessary.
- Emoticons spread rapidly across ARPAnet, becoming a standard feature of online communication.
- A "digital archaeology" project recovered the original 1982 bulletin board thread, highlighting the collaborative development of the emoticon.
- Emoji, originating in Japan in the late 1990s, evolved as a parallel system of pictographic images.
- Fahlman's contribution was significant for proposing a timely and contextually appropriate solution, not absolute originality.
