When it comes to the average age of television viewers for new shows, CBS watchers are generally older, while Fox viewers are generally younger, according to The Hollywood Reporter.
The average age of a viewer watching the Fox animation series "The Cleveland Show" is 28. On the other end of the spectrum, CBS’s "The Good Wife" and "Three Rivers" draw viewers who are a median age of 57.
CBS’ top-rated drama series, "NCIS: Los Angeles" is right behind those two with viewers who are 56 years old on average.
