Felix Arvid Ulf Kjellberg ( SHEL-burg, Swedish: [ˈfěːlɪks ˈǎrːvɪd ɵlf ˈɕɛ̂lːbærj] (listen); born 24 October 1989), known online as PewDiePie ( PEW-dee-py), is a Swedish YouTuber, comedian, gamer, and philanthropist, known primarily for his Let's Play videos and comedic formatted shows.
Born and raised in Gothenburg, Sweden, Kjellberg registered his eponymous YouTube channel in 2010, primarily posting Let's Play videos of horror and action video games. His channel experienced substantial growth in popularity over the next two years and he reached 1 million subscribers in July 2012. Over time, his style of content diversified to include vlogs, comedy shorts, formatted shows, and music videos.
Kjellberg's channel became the most-subscribed channel on YouTube on 15 August 2013. After being briefly surpassed in late 2013 by YouTube Spotlight, his channel firmly held the title until early 2019, when he publicly vied for it with Indian record label T-Series. The latter established a significant lead in April that year, and Kjellberg's channel currently remains as the second-most-subscribed on the platform, having received over 107 million subscribers as of 22 November 2020. From 29 December 2014 to 14 February 2017, Kjellberg had the most-viewed channel on YouTube, and as of 22 November 2020, his channel has received over 26 billion views, ranking as the 19th-most-viewed channel on the platform. His channel's subscriber count ranks as the most among those operated by an individual, while its view count is the sixth highest among those operated by an individual.
Kjellberg's popularity on YouTube and extensive media coverage have made him one of the most noted online personalities and content creators. Due to this audience and media attention, his coverage of indie games has created an Oprah effect, boosting sales for titles he plays. In 2016, Time magazine named him one of the world's 100 most influential people.
