The makers of the KitKat chocolate bar are taking their own advice and having a break from using the company's 47-year-old slogan: "Have a break - have a KitKat".
Instead Nestle Rowntree is replacing the iconic statement with: "Make the most of your break."
KitKat's famous tagline was first used with the chocolate bar's debut television advert in 1957, but will disappear when the new catchphrase is introduced in a £5m campaign starting next month.
Nestle Rowntree decided to make the change after extensive market research showed that while most people knew the slogan, it had little effect in convincing them to buy the product, which is made in the firm's York factory.
A company spokeswoman said: "We are introducing a new advertising campaign to consolidate KitKat's position as one of the UK's best-selling chocolate bars.
"It reinforces KitKat's ownership of key snacking occasions, and offers consumers a fresh reason to buy the brand for these occasions."
Earlier this year the firm announced that sales dipped in 2003 by 9% to £95m, despite KitKat remaining Britain's favourite chocolate snack.
The spokeswoman said sales had picked up recently, pointing to a 10% rise in the past eight weeks.
The manufacturer says 47 of the chocolate bars are eaten every minute and it has no plans to change the taste of KitKats.
The brand was launched in 1935 as Rowntree's Chocolate Crisp, and was endorsed by the second world war government of Winston Churchill as a cheap and healthy source of nourishment.
