In 2000, when Derek Arnold created International CAPS LOCK day, it was a parody, making fun of those people who insist in typing everything in ALL CAPITALS. But, as it happened, it became more and more popular, with people celebrating it just for the key itself. No parody at all. The day became so popular with internet users that it is now celebrated twice a year—on June 28 (this Sunday)and on October 22. But, WHERE DID WE GET THE CAPS LOCK KEY FROM?!?
Early on in Internet history, Internet users had only text keys to show emphasis, no fun yet strange emoticons that can create entire conversations by themselves. They used **** and CAPS to differentiate their thoughts and emotions. Some people, holdovers from early Internet days perhaps, still type messages in all capitals. Nowadays, writing in ALL CAPS has become an etiquette NO-NO, since it is the equivalent of shouting online. Every once in a while for emphasis is considered OK, but not everything in caps. People have gotten fired for using all caps all the time. REALLY! In 2007, a woman in New Zealand was fired from her job after she sent one too many memos in all caps.
