An oddity of the current day and age is that people let children on a service like YT without supervision.

As a child, my parents vetted anything I watched that was not a broadcast children's TV show. Adult themes and violence were filtered until an age that was considered safe.

This was also a time when the TV schedule could be known in advance. There was no on-demand anything - pre-VCR. I can't imagine handing a child the loaded gun of the internet and letting them point it at their developing heads.
