In the TV campaign, “7 Days in a Sentra,” a quirky, young Marc Horowitz tests out his new Nissan Sentra by living in it for a week. Our interactive challenge: to introduce the Sentra story to a young, media-savvy target who was tired of having their party crashed by hard-selling corporate blogs and MySpace pages. The solution: in a peer-to-peer world, we needed to be a peer. Partnering with Marc Horowitz, we translated our campaign into authentic peer-to-peer communication, eliciting extraordinary interaction between our target and the “7 Days in a Sentra” experience.
