In my region, commercials were shown for evening shows/sitcoms. I forgot the name but pens and jrking were mentioned as part of the teaser. This happened more than once. So, I don't think they realise...

I do not allow anymore, as this is seen as a spoiled kid with too many toys/attention in our house. We rather focus on having toys that last, like Lego. The way this is portrayed is subliminal as the kids are unaware of it being sponsored. The real show or review element is hardly there.

Although, some stuff I easily allow, like coilbook, super simple songs or race grooves or some stop motion videos...
