From this story in The New York Times:
What have programmers at the television networks been thinking, putting on all those shows about cops, doctors and lawyers? America's fascination has clearly turned in another direction: ducks. The A&E series "Duck Dynasty" has become a raging hit. The season finale, an hour-long edition Wednesday night, set new records for the series, scoring a best-in-television 3 rating from 10 to 11 p.m., among the advertiser-preferred audience group of viewers between the ages of 18 and 49. Really more about a quirky bayou family that makes duck calls and decoys than about the birds themselves, "Duck Dynasty" is now the top-rated series in A&E history.
