The most famous slogan of Mars chocolate bars is ‘Work, Rest and Play.’ It was used until 1997, when it was replaced by the phrases ‘Pleasure you can't measure’ and ‘Must be Mars.’ In 2007, the motto ‘Work, Rest and Play’ returned, but with the addition of the phrase ‘Play Longer.’ This came at a time when Mars was positioning itself as a sports-related brand. In 2015, another slogan appeared: ‘Put some play in your day.’ None of them were part of the logo.
