He’s the highest-paid star on YouTube, and he didn’t even start wiping his own behind until “Game of Thrones” was four seasons in.

His name is RYAN KAJI, he’s 8 years old, and his Ryan’s World channel raked in $26 MILLION over the past year.  He was also #1 last year, with $22 million.

Ryan’s channel launched five years ago, and used to consist mainly of him unboxing toys.  Now he’s posting several videos a week, doing whatever.  (The video above is one where he grows his own bacteria.)

He has almost 23 million subscribers.

The second biggest channel this year was “Dude Perfect”, those five guys who play sports, perform stunts, and break Guinness World Records.  They made $20 million this year.

Coming in third was 5-year-old Anastasia Radzinskaya, who earned $18 million.
