The median age of the television audience is now 50,according to a study released by Magna Global's Steve Sternberg and reported in today's (Monday) Daily Variety . The median age -- different from the average age -- represents a dividing line. In the case of the Sternberg study, half the U.S. television audience is younger than 50; half is older than 50. The latest figures represent the first time that the median age has fallen outside the 18-49 demographic, advertisers' most desired demo. "The median ages of the broadcast networks keep rising, as traditional television is no longer necessarily the first screen for the younger set," Sternberg wrote.
