Mars is reviving its 'Work, Rest and Play' slogan after a decade off the screen, but has ditched the 'Mars a day' claim to meet today's health labelling rules. The iconic slogan, first used in commercials in 1959, will be used in a TV ad from next week after it was "inundated" with requests to bring it back, said trade relations manager Bep Sandhu. "The original strapline is an important part of the brand's heritage and success," she said. Although the ad does not recommend a Mars a day, the creative focuses on the boost that eating it can give people. The first ad, Bell Ringers, features monks. Last year, Mars denied it was planning to revive the slogan after it introduced 'Work. Rest. Play longer' on to packs of its Refuel drink. In the past year, sales of Mars have risen just 0.2% to £104.2m [Nielsen 52 w/e 6 October 2007].
