Felix Kjellberg, better known as PewDiePie, made a lot of money last year. His company, PewDiePie Productions, brought in about $7 million in revenue, mainly off of Kjellberg's YouTube videos where he plays video games and reacts in silly ways. With those videos, he's also raised more than $1 million for charity over the years. Kjellberg has 37.7 million subscribers on YouTube and about 9 billion views overall -- considering that he receives ad revenue based on the number of views his videos get, it's not surprising that he's making serious bank. However, When news of Kjellberg's revenue hit the 'net, quite a few people responded with anger, outrage or thinly veiled jealousy, as they do any time that PewDiePie's revenue goes public. This year, Kjellberg made a video addressing the money issue, including a brief description of his not-so-glamorous life before YouTube.
