The median live broadcast viewer age for the five US networks is over 50. Fox News clocks in with a median over 65. If they want the tasty 18-49 demographic, they need to get the cable and YouTube viewers. I’ve watched more video in the last year than the ten before that, most of it YouTube fripperies to amuse my baby daughter. The rest being Weebl & Bob. Wonder what the BBC iPlayer numbers are.
