The key in OOH advertising is finding a way to engage your audience, and Ogilvy & Mather Berlin certainly managed that with these brilliant billboards advertising their client, sports drink company Powerade. Regular billboards on the streets of the German capital were turned into workout equipment such as a moving climbing wall, a weight-lift, and a punch-bag (or punch…board). Curious pedestrians were encouraged to try out the exercises and then rewarded with a bottle of Powerade to quench their thirst after their experience. An eye-catching campaign which is fun as well as memorable. Watch the video below.
