Khan Academy

Khan Academy (click here for link ) is a non-profit educational organization and a website created in September 2006 by Bangladesh-American educator Salman Khan (Sal), a graduate of MIT and Harvard Business School. With the stated mission of "providing a high quality education to anyone, anywhere", the website supplies a free online collection of more than 5,500 micro-lectures via video tutorials in nearly 30 languages. These lectures are stored on YouTube, and their topics include mathematics, history, healthcare and medicine, finance, physics, chemistry, biology, astronomy, economics, cosmology, organic chemistry, American civics, art history, macroeconomics, microeconomics, and Computer science. Since its founding in 2006, Khan Academy has delivered over 600 million lessons to thousands of people worldwide. Plus, even now the number is growing.

History
The Khan Academy started with Sal Khan remotely tutoring one of his cousins interactively using Yahoo Doodle images. Based on feedback from his cousin, additional cousins began to take advantage of the interactive, remote tutoring. In order to make better use of his and their time, Khan transitioned to making YouTube video tutorials. Drawings are now made with a Wacom tablet and the free natural drawing application SmoothDraw 3, and recorded with screen capture software from Camtasia Studio. In 2010, Khan Academy released Badges, which track your progress as you learn a skill.

Outside Support
The site has been funded by many outside sources, including Google, Micosoft, Carlos Slim, and Bank of America.
