KitKat encouraged the British public to ‘have a brrr’ from the cold weather we experienced earlier this January in a play on their classic ‘have a break’ tag line. This OOH campaign may seem simple, with just three words of copy, but by reacting to Baltic temperatures that swept the nation and going from concept to implementation in just 36 hours the campaign was not just innovative but effective. Because the ad was so relevant to what was going on at the time, it not only demanded more attention from the viewer but was likely to be more memorable too as it would stick out against less relevant advertising.
