The season premiere [of Duck Dynasty] got huge ratings in the Lake Charles, La. media market, where more than 52 percent of households tuned in. The show got ratings higher than a 30 percent share in 25 media markets, which National Medias Will Feltus tells us is comparable to most Super Bowls. Of the top 15 media markets that tuned in to the premiere, only three Lima, Ohio, Charleston, W.Va. and Evansville, Ind. are outside the South.
The show did worst in the San Francisco, San Diego and Los Angeles media market, where only 2.5 to 3 percent of households tuned in. New York, Boston, Las Vegas and Chicago were all near the bottom in media market performance.
Here's the map showing where the program is viewed:
