Over 20 pizzerias in the Philadelphia area (those in close proximity to large college campuses) were supplied with Economist-branded pizza boxes. Each pizza box [adsoftheworld.com] highlighted a specific data statistic, such as "Arable and permanent crop land by country" and "Mushroom exports to the U.S.".
After the pizza, one can always try a pie pie chart for dessert.
