Smiles are a representation of facial expression. Smile icon is a yellow face with smiling eyes and a broad, closed smile turning up to rosy cheeks. Often expresses genuine happiness and warm, positive feelings.
The first introduction of Smile symbol in popular culture happened in 1963. It was part of a promotion by New York radio station WMCA. Fans who answered their phone “WMCA Good Guys!” would get a reward of a “WMCA good guys” sweatshirt that included a happy face into its design. Thousands of these sweatshirts were given away. In 1963, Harvey Ross Ball, an American graphic artist, created the smiley face as we know it today. It was a yellow circle with two black dots representing eyes and a black arc representing the mouth.
Smiles became a feature of popular communication apps of the 90’s such as MSN, Yahoo, and AOL Messenger. They still are a big part of popular social networks such as Facebook, Twitter, Snapchat, and Instagram.
