TV watchers' average age is now 50 - the oldest ever, according to a study by Magna Global's Steve Sternberg.

From Variety.com:

At ABC, youngest series was "Supernanny" (with a median age of 41), while oldest was "Women's Murder Club" (57). At CBS, youngest was "How I Met Your Mother," "Kid Nation" and the Tuesday edition of "Big Brother," tied at 45; oldest was "60 Minutes" (60). NBC's youngest show was "Scrubs" (34), and oldest was "Monk" (58).

At Fox, the youngest shows were "American Dad" and "Family Guy" (29), while the oldest was "Canterbury's Law" (55). At CW, "One Tree Hill" was youngest (26), while "Life Is Wild" was oldest (45).

Among late-night gabbers, "Tonight Show With Jay Leno" is oldest, with a median age of 54, followed by "Late Show With David Letterman" at 53. Interestingly, "Nightline" -- which should conceivably be older than those talkers, is younger, at 52. ABC's "Jimmy Kimmel Live," meanwhile, passed the 18-49 threshold for the first time, clocking in with a median of 50. "Late Night With Conan O'Brien" is getting closer at 46.

Honey, I wish you would turn that TV off - go outside and enjoy your mid-life crisis.
