response: Well, for the Nelson rating, the show ranks really high so that's is why AMC renews it yearly.
original_response: Nielsen ratings rank the show very high for a cable series.
history: I live near where they film the walking dead. Ah so you must live in Atlanta or Alexandria? They fil it in Semoia, GA. That is correct. That's cool. The show premiered back in 2010 in the US. Correction, Senoia, GA  Pronounced Snoy.  Yes, i watched the first few episodes of season 1 but then gave up. I see, well the show had the most 18 to 49 year old viewers watching it starting with season 3. Millennials have no taste in entertainment.
knowledge: As a result of very favorable Nielsen ratings that rank the show unprecedentedly high for a cable series, AMC has renewed the series each year.
