ABC, NBC and Fox continue to grow older, while CBS--the oldest-skewing network--has remained fairly steady. "With traditional
television no longer necessarily the first screen for the younger set, the ages of the broadcast networks keep rising," says Magna researcher Steve Sternberg.
When DVR viewing is factored in, the nets (except CW and Univision) drop by only a year. Sternberg notes that Fox and CW maintain median ages that are closer to the actual age of the population, which averages 38.
