The studies I linked are for kids under 2. TV for under two year olds is detrimental, but research shows viewing sesame street between ages 3-5 for less than 2 hours per day is associated with language benefits all the way into adolescence (happy to post links). Paeds agree that Educational shows and slow-paced cartoons in small amounts is a great tool for preschoolers. Violence/fast-paced Cartoons/background TV is bad for preschoolers.
So yeah, I agree with you. everything in balance, select content carefully, and try to avoid TV for infants. It's not really that radical.
