KhanAcademy started when Salman Khan tutored one of his cousins in mathematics on the Internet. Slowly, his tutelage expanded from one of his cousins, to several other cousins, to the entire world. To think that something as influential as the KhanAcademy started from fulfilling a very simple need for a particular person should help inspire people to engender as much change as they can to people.
