PCGH Retro: The invention of the smiley :-)
Once again PCGH takes a look at the short but eventful history of the computer. Today: What happened on September 19?
...1982: From this day on it is easier to express feelings in digital messages: At 11:44 o'clock the Emoticon, also known as smiley, is invented. During a discussion on the computer network of the Carneige Mellon University the student Scott E. Fahlmann suggests to mark humorous contributions with a smiley made of ASCII characters: :-) Serious comments on the other hand should be marked with :-(. Several other symbols had been discussed at that time. You can find the original discussion right here.
...1989: An early version of the Y2K Bug crashes some computer systems. Some programs can cope with 2^15 different days only, that's 32,768 days from 1. January 1990, the initial date for their calculation of time. Therefore September 19, 1989 would have been day 32.769 for them.
...1994: Apple announces that several companies got the license to produce Apple clones with Mac OS. Before that day Apple always refused to allow clones - and it has been those devices that affected IBM's PC business, but in the end helped the x86 PC to be successful. The alterative Macs actually didn't attract that much attention.
