They do. Kids-wise, we'd be fine without Disney+ and Netflix. My youngest is a big fan of Thomas the Tank Engine, but even on Youtube, he doesn't want to see the actual Thomas shows, but videos of people playing with Thomas toys. No idea why this is such a popular thing, but my oldest watched people play Mario at that age. And now he watches people play Minecraft.
I don't get it. Go play these things yourself, but apparently kids love to watch others play, and there's tons and tons of that on Youtube.
