Of course the videos are "among its most popular". You know those inane autoplaying videos after you just watched something where everyone rushes to stop the countdown? Well, kids don't. Lazy parents all over the world park their kids in front of YouTube, and they will happily watch whatever inane crap YouTube throws at them for hours on end. Except for the lack of spending money, they are the perfect viewer. It's disturbing watching young kids "use" YouTube, watching repeats or slight variations of the same mind numbingly stupid video for hours, lulled into an algorithmic trance hitting their brain just right, without the maturity to break the vicious cycle.
