On the Internet in e-mail, chatting, and text messaging, an emoticon (sometimes referred to by the name of the original emoticon, the smiley) is a short sequence of keyboard letters and symbols, usually emulating a facial expression, expressing a feeling that supplements the message. Mike Jones, who works in the systems and networking research group at Microsoft's headquarters in Redmond, Washington, has determined that the first smiley was posted on September 19, 1982.
