The Economist wants college students to learn more about global affairs while eating pizza. The publication's new brand boxes use pie charts to express statistics on global wheat consumption, arable crop land, and cheese imports, as part of their "get a world view campaign". The boxes are distributed nearby Philadelphia-area college campuses.
