Khan first made a name for himself by recording Youtube videos on mathematics for his cousin, which quickly went viral. As he says "No tutor would sit there and repeat the same thing 20 or 30 times but the videos let me do that without judgement."
Khan has produced over 3300 videos covering a wide spectrum of academic subjects, mainly with a focus on mathematics and the sciences. He has attracted more than 355,000 subscribers.
In the period of a few short months, he went from making videos in his closet to getting $2M from the Gates Foundation and $2M from Google. Khan videos are now available in multiple languages, even Mongolian - voice overs being produced by an army of dedicated volunteers.
