The maps are somewhat (ok, a lot) misleading because they show land area, not population. Duck Dynasty looks like a giant hit in Harney County, Oregon, but come on, there's only 7,146 people living there (2013).
Well, it makes it look like a big hit in Harney County, OR, and a flop in Portland. Which appears to be accurate-- of the people in Harney County, lots of them watch Duck Dynasty. There isn't much fine print there.
