When Kjellberg's revenue numbers hit last year, he was inundated with questions and messages of incredulity -- so many that he did a Reddit AMA to clear the air. He confirmed the $4 million figure and noted that he does charity work alongside his "Let's Play" gaming videos: "I still spent far more money on charities than anything I've ever spent for myself. Which I am proud to say at least." In June 2014, Kjellberg announced that his bro army (see: fans) had raised more than $1 million for various charities, including the World Wildlife Fund, Save the Children, St. Jude hospital and Charity: Water. In March this year, Charity: Water thanked Kjellberg for helping 10,028 people in Rwanda get access to clean water. Not bad for a band of bros.

Kjellberg's next big thing is the launch of his book, titled This Book Loves You, a collection of inspirational quotes that he's said over the years as an online personality. For example: "Don't be yourself. Be a pizza. Everyone loves pizza." This Book Loves You is due to drop in October.
