Lever Brothers is launching a new Domestos TV commercial this week, as part of a &£3m marketing campaign, through Lowe Lintas. The ad, called ‘Swimmer’, features a brother and sister playing on the kitchen floor, imagining they are having an aquatic adventure, surrounded by fish. The endline is ‘Domestos protects. Even in the world you can’t see.’ The campaign will be backed by press ads, in-store promotions and direct marketing activity. Initiative is handling media.
