I wonder if there's some kind of startup here. A service that whitelists YouTube content and curates the list. There could be an app you sign into before you hand it off to the child, it permits only whitelisted YouTube videos to be played. Possibly the videos are separated into tiers - educational, entertainment, prosocial. Then, you come up with a mix that you want to expose your child to for auto play - e.g. 40, 20, 40. Content could also be flagged for themes that are potentially undesirable - death, sex, religion, etc.
Pay 15-20 dollars an hour for people to watch and annotate videos. Get the same video to go through the process two or three times to catch potential errors. Your evaluators can easily watch content at 2x speed and not miss much. How much does processing an hour's worth of YouTube video cost? 60 dollars?
Invest a hundred grand, whitelist a thousand hours of YouTube content (assuming you reject half), build a simple mobile app to play your whitelisted YouTube videos, sign people up for 5 dollars a month and you can use the proceeds to keep growing your whitelist.
I found an article talking about it. It's pretty mild stuff, but an interesting illustration of how what we consider appropriate changes in all kinds of small ways:
> What parent today would want their child to see kids running through a construction site or jumping on an old box spring? Scenes like the ones included on the new DVD would probably not make it into today's program now.
> "We wouldn't have children on the set riding without a bicycle helmet," Rollins Westin says.
> And what's that little girl doing with that man?
> "In the very first episode, Gordon takes a little girl's hand who he's just met on the street, befriends her and takes her into his home to give her ice cream," Rollins Westin said. "That's something we wouldn't do on the show today."

With this kind of normalization of hanging out with strangers on TV, I am not really surprised that children were more likely to be abducted in the 70's and 80's.
