This is such a polarised debate.
DS1 watches about 0.5 hrs before school (while I get ready), and about 1 hr after school. On non-school days he also watches about 1 hour max after lunch, while DS2 is asleep and I have a rest. He eats well, is well behaved, doesn't understand the concept of adverts (only watches Cbeebies or videos), sleeps well, doesn't say 'I want I want' - in other words is perfectly normal, happy, well adjusted, polite, lively child of 5.
We have a TV in the living room. Will never have one in the bedroom or the kitchen. We eat together at the kitchen table. Sometimes for sandwich-type tea I let DS1 watch TV with a tray on his lap.
There is crap TV, and good TV. FGS just make an informed choice. Don't demonise the messenger, just choose the message! There are crap books and good books too!
