Ad agency research firm Magna Global released a study this summer, breaking down the median audience age of every show on network television during the 2009-2010 season. On the whole, Magna Global reported that the median audience age for all of broadcast television has risen to 51. Not surprisingly, CBS has the oldest median audience; its average viewer is 55 years old. Below, see some of the shows that have the oldest median audience on television, and tell us if you watch them--or if you didn't even know they existed.
