I would argue the effect of smoking was also a lot longer to see the effect. I've been to countries where kids smoke (middle east) and there's no apparent effect on the smoking kids. You'd probably have to wait until their 30s to really see the damage. Watching a kid watch TV there is almost an immediate feeling of unhealthiness that isn't as apparent from watching a kid smoke. The smoking kid will keep on playing soccer, the kid on the TV is sucked into the sedentary low-thought activity like they're in a trance.
