Mars used the slogan “A Mars a day helps you work, rest and play.”
The slogan promoted the Mars bar as a small energy-giving treat suitable for different parts of the day. Its rhythm and three-part structure made it easy to remember, while the words “work, rest and play” broadened the product’s appeal beyond a simple confectionery snack.
Mars, Incorporated was founded by Franklin Clarence Mars in 1911. The company’s Mars bar was introduced in the United Kingdom in 1932 by Forrest Mars and was based on the American Milky Way bar, though the recipes differed between markets.
The slogan is associated with the Mars bar rather than the company’s entire global product range. Mars, Incorporated also owns brands such as M&M’s, Snickers, and Pedigree.
