He may not exactly be well known by most adults, but one would be hard-pressed to find a bigger star of YouTube Kids. This eight-year-old makes unboxing and toy review videos, and he was the highest-earning YouTuber of 2019, according to Forbes Magazine. He beat out Markiplier, PewDiePie, and Jeffree Star, two gaming YouTubers, and a beauty YouTuber, who make up some of the highest earners on the platform. He raked in a total of $26 million last year, out the second-place earner, Dude Perfect, a sports and comedy channel, by $6 million.
