While I generally do not like the hypocritical puritanism in American society, I do like that on Network TV and basic it is understood that the programing willbe less blue than HBO and that network TV will be especially tame.
If everything on TV were like HBO, I could never even watch a show with family members beside by brothers and cousins. I watch Breaking Bad with my parents andit is awkward enough when the show hints as sex and I tried to watch HBO's Rome with my family and it is was just too awkward. So I do like kinda knowingin advance that if a show is on a certain network or channel it will not be too awkward to watch with one's own mother.
