* ssl.google-analytics.com (tracking)
* pagead2.googlesyndication.com (a google ad domain)

From their Privacy Policy [1]:
> We also may share aggregated or anonymized information with third parties, including to help us develop content and services that we hope you or your child will find of interest or to help these third parties develop their own products and service offerings.
The above paragraph with the associated list of domains being used above screams targeting to me
> We may allow third parties to place and read their own cookies, web beacons, and similar technologies to collect information through the Services.
So they let 3rd parties do whatever they want. The full privacy policy is followed with an example use case of how its helpful and useful, but just like Facebook's privacy policy the examples are misdirection.
And else just make them watch finger family videos for hours.
There are a few interesting channels, but otherwise I may as well be watching regular tv. The suggestions I get are also incredibly bad.
