CBS is always mildly right-conservative. Pro police etc. NBC is liberal. ABC waffles.
It’s funny – I don’t watch regular TV much anymore but the little I do, the demographics for CBS and NBC and ABC never seems to change. I’d expected greater changes in ABC through the years because of buyouts and things yet it hasn’t.
If I had to summarize:
CBS: Blue Bloods, CSI, Murder She Wrote.
NBC: SNL, 3rd Rock
ABC: Home Improvement, Roseanne, America’s Funniest Videos.
CBS is grandma/grandpa
NBC is middle age city liberal
ABC is suburban conservative family mom who THINKS she’s progressive but it surprisingly traditional.
