Even a smiley also got birthday :-), billions of people is using this smiley in their email, according to source from Ananova, the smiley was invented by an IT expert in Pittsburgh, US, reports The Sun. I would say he's the first person who's just lucky to have computer at year 1982 and type out such thing because he's a professor.Prof Scott Fahlman was the first to use a colon followed by a hyphen and a close bracket to form a smiley in a computer message. What next? who is invented or :P.
