HBO's original programming is all about groundbreaking television. So we wanted to bring that same attitude to their online effort as well. To support Atmosphere BBDO's efforts for "Curb Your Enthusiasm: The Complete Fourth Season", "Carnivale: The Complete First Season" and "Cathouse", we didn't just tell people that a new HBO DVD was being released. We got them to taste and experience what they might be missing through engaging imagery, in-banner video, games and more.
