The Chocolate Orange product is known for its unusual marketing, which is usually at its heaviest around Christmas. At one time it was estimated that the Chocolate Orange was found in a tenth of British Christmas stockings. Actress Dawn French has fronted numerous campaigns for the brand, often in a posed scene of defending and hiding "her" Chocolate Orange from others. Famous marketing phrases include: More recent advertisements (after the rebranding) do not feature French and contain the new slogan "Round but not round for long" (some include the Countdown timer music).
