Felix Kjellberg, better known as PewDiePie on his YouTube channel, has been ranked by Forbes as the highest-earning celebrity on the online video-sharing platform, making over $12 million in the last year alone.

The 25-year-old star shares many things on his channel - from how to talk to girls, to Googling yourself and reading comments. One thing that he has maintained throughout his videos is how he has never lost sight of who his audience is - one that wants to be informed as well has have some fun while at it, The Examiner reported.

Kjellberg has also topped Variety's list of Famechangers, the digital world's 12 most influential stars. The 40+ million followers on his YouTube channel are only testaments to his influence. Among the other YouTube sensations that made Forbes' list is Chanteuse Lindsey Stirling, who has earned $6 million and also made the Famechangers list.
