I would say it depends a lot on environment the children are raised in, I grew up in the 90's my family had one television set in the house (in our families living room) and it was only turned on if someone was watching a program. There was a tv guide which you would consult, if there was nothing you were interested in then tv would never get turned on. My Dad in particular would get annoyed at what he saw as "needlessly flicking between channels".
I can remember visiting friends houses where there would be multiple television sets (including tv sets in bedrooms) and television would always be turned on, even if no one was watching it. It was like a constant low level background noise. I found it strange but it was normal to them, they were used to eating dinner or playing with legos etc with tv constantly on in the background.
