I know about Netflix, Hulu and YouTube. Are there other good sources of video content, especially free ones?

While I scour the internet for an answer I will cast a line and ask here too.

Our son is using a Chrome Stick for home schooling. As typical 13yr olds do his mind wanders to questionable videos on YT for his age. We created a Supervised User account to control his access to it, but he recently discovered he can watch all the YT he wants if he simply inserts in in a slide from Google docs.

This seems to be a pretty glaring loophole Google has overlooked unless I've simply not found the spot to block it yet.

Any ideas on how we might block Google Slides froma Supervised User? Seems to be an integral part of a Google Account so we can't figure it out yet.

Domain restrictions are strange too. I'm thinking maybe using a wildcard to block anything with the Google Slides url string in it? The problem there is once in a while the little jerk needs it for school.

Halp!

I'm looking for a list of music services that work on Chrome OS. What are you using?
