Half of the pictures and videos from concerts are of a stranger's back, and the other half is the stage. Hellmann's saw the opportunity to leverage this space that had never been used before and propose an experience where everyone benefited. Hellmann’s and Ogilvy Argentina stormed Argentina's largest rock festival with “Tasty Backs,” the first campaign to use people's backs as an advertising medium, pushing the boundaries of creativity in an unprecedented experience for consumers. We invited the tallest attendees to be Hellmann's "backs," wearing a t-shirt with a brand advertising design, in exchange for flavor. At the same time, shorter attendees, who often feel "blocked," also received their reward for sharing content. In this way, we managed to connect the brand with the public, generating participation and a fun atmosphere.
