This is fantastic! The New York Times has compiled ZIP Code-based choropleth maps of the top DVD rentals for 2009. They have mapped the top rentals for twelve metropolitan areas in the United States. Use the slider above the map to choose the top-rented movies to see how the ZIP Code shading changes based on the the rank of the movie in that ZIP Code.
