An interesting article from the Los Angeles Times, on who is still watching network television:
Until recently, the broadcast television networks have been virtually transfixed on younger viewers. NBC, in particular, led in the 18-49 year-old demographic during the 1980's, '90's and early 2000. The Fox network virtually built itself on that "demo".
And even my 20-something co-workers appreciate the old shows. One told me she's a devoted I Love Lucy fan. You can't get much older than that show.
As another article recently proclaimed: Anyone for another Matlock?
