In 2008, Sal Khan had a bright future making millions as a hedge fund manager. He gave it up to produce low-budget math films on YouTube for free. Fortunately, hidden among his millions of loyal students, were the wealthiest of educational philanthropists, Bill Gates and the Google Foundation. Now, with a whole lot of cash and even more street cred, Khan aims to demote the institution of "school" to just one of many educational options.
Khan Academy, the YouTube open-course series, began as verbal contract with a 7th-grade girl. His younger cousin, Nadia, was struggling in math class and had agreed to sit in on remote tutoring sessions. After she skyrocketed a few grade levels in ability, more family and friends wanted in on the action, eventually forcing Khan to record the lectures online.
Since YouTube encouraged universal access, Khan thought “Why not?,” and made the lectures public, on the off chance someone beyond his immediate friends and family would ever take an interest in his mathematics lectures. The result was shocking, and the audience exploded.
