The play button is taken from the time when tape was a popular music medium. It simply symbolised the direction the tape is moving. The other symbols popularised during the era of the tape are the rewind button, which points to the opposite direction, and the fast forward and fast rewind buttons which used double arrows to mean increased speed.

There are two origin stories for the ‘at’ symbol used in email addresses. The first says that it is taken from 6th century monks who used the symbol to denote the Latin word for ‘at’ or ‘toward.’ The second says that it was used by programmer Raymond Tomlinson to separate the user and the terminal in computer network addresses. The ‘at’ sign is also called ‘monkey’s tail’ in Germany, ‘snail’ in Italy and France and ‘little mouse’ in China.
