Eight-year-old is highest paid YouTuber, earns $26 million in year
The "Ryan's World"
Kaji, whose real name is Ryan Guan, was already the video platform's highest earner in 2018, with $22 million, according to Forbes.
His channel "Ryan's World," launched in 2015 by Ryan's parents, is only three years old but already has 22.9 million subscribers.
Initially called "Ryan ToysReview," the channel mostly consisted of "unboxing" videos -- videos of the young star opening boxes of toys and playing with them.
Unboxing billions of views
Recently, the channel was renamed after a consumer advocacy organization, Truth in Advertising, filed a complaint with the US Federal Trade Commission (FTC) about it.
Truth in Advertising accused the channel of not clearly denoting which videos had been sponsored, meaning brands paid for the video to feature their products.
Little boy's magic
In Forbes's ranking, Ryan Kaji surpassed the channel "Dude Perfect," run by a group of friends from Texas who attempt seemingly impossible feats, such as launching basketballs into hoops from the tops of buildings or out of helicopters.
The kids are killing it
According to the FTC, the platform used the data to ensure that advertisers were able to target children.
