Marbury compares the ad to Obama.
Obama and that Cadbury ad are both successful, at least in part, because people are not quite sure what they mean. So people want to talk about them, and write about them, and debate them at length. And - crucially - email, post and create their own user-generated videos about them. In this way do the chocolate bar and the politician become media phenomena. In the age of the web, a little bit of ambiguity is a very powerful thing.An interesting take.
