:-)

Its been claimed that its 25 years since :-) was used for the first time. It is believed that twenty five years ago, a Carnegie Mellon professor Scott E. Fahlman was the first to use the three keystrokes (":", "-", ")") to represent a smiley in a message.
Since then the messaging industry has added so many emoticons, that it seems almost impossible to send a computer message without using an emoticons.
The creator of the original ASCII emoticons :-) and :-(, with a specific suggestion that they be used to express emotion, was Scott Fahlman; the text of his original proposal, posted to the Carnegie Mellon University computer science general board on 19 September 1982 (11:44), was considered lost for a long time. It was however recovered twenty years later by Jeff Baird, from old backup tapes.

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

:-(
