Before the name was changed to Snickers in 1990, the candy bar was known as Marathon in the UK. The name Marathon was first introduced when the candy bar was launched in 1930 by the Mars company in the UK. The name was changed to Snickers to bring it in line with the name used in the US and other countries, where the candy bar had been called Snickers since it was first introduced in 1930. The decision to change the name from Marathon to Snickers was made to create a global brand identity for the candy bar.
