There's no comparison, Rich.

I retired from teaching in 2014 and there was a marked change in kids' fixation on computer games during my final 5 - 10 years. At recess and lunch-hour, a dominant topic among the kids was their games: Minecraft, Grand Theft Auto, various motorcycle-riding simulators, etc.
As students headed for the bus at the end of the day they would discuss what level they were at, what level they hoped to achieve that evening, who they'd be playing with, etc.

Others were into rap videos, even whispers of porn sites, perhaps even worse.

Parents complained that they couldn't get their kid in bed... they'd catch him playing at midnight, then he'd refuse to get up & go to school. 

Students who misbehaved openly said, "Good... send me home. I'd much rather play ___ than be in school."

I think the ballooning obesity rate is due more to screen time than it is to diet. Some kids would rather play than eat...much less socialize in the real world.
