PewDiePie
PewDiePie was born on 24 October 1989 in Gothenburg, Sweden. Before starting his own YouTube channel, PewDiePie studied Industrial Economics and Technology Management at Chalmers University of Technology until he dropped out. Disapproving of his decision, his parents cut off his support. He made a living by selling hot dogs until his channel got enough subscribers for him to make a living from the channel.
