YouTube

Did you know the highest YouTube earner in the world is a woman with perfectly manicured nails who opens kids toys and plays with them?  You never see her face or body, just her hands. There are hundreds of people who review toys. Some of them do it with their kids, but most of them are adults who know the name of every Hotwheels car.  

You might be thinking, what is the target audience? Who on earth would watch that?

Right there. That's it.
