AKA: Felix Kjellberg

Location: United Kingdom

Video type: PewDiePie is known for his popular videos where he gives commentary while playing video games. His content has expanded into coverage and commentary of internet memes and viral videos.

At one point, the Swedish gamer was locked in a months-long battle for the title of most-subscribed-to YouTube channel with Bollywood music company T-Series. His devoted fanbase took action to ensure his No. 1 spot with an extensive "Subscribe to PewDiePie" campaign that included hacking printers and buying billboard space. However, T-Series beat PewDiePie to the 100-million subscriber mark at the end of May 2019.

Kjellberg has also attracted negative attention for a long history of offensive racist and anti-Semitic remarks, which YouTube has punished him for. As of late, he's on an extended hiatus from YouTube — but his channel continues to dominate the charts.
