Khan Academy is popular for its videos distributed to help people learn. It is a non-profit educational organization created in 2006 by educator Salman Khan to provide:
a free, world-class education for anyone, anywhere.
Khan Academy’s website offers thousands of educational resources. It also contains many other features such as progress tracking, practice exercises, and a variety of tools for teachers in public schools. The organization is now financed by donations and with significant backing from the Bill Gates and Google. In 2010, Google announced it would give the Khan Academy $2 million for creating more courses and for translating the core library into the world’s most widely spoken languages
Salman Khan, the founder of the organization, was born and raised in New Orleans, Louisiana, United States to a father from Barisal, Bangladesh and mother from Calcutta, India. He earned three degrees from the Massachusetts Institute of Technology and pursued an MBA from Harvard Business School.
To help his relatives and friends, especially a cousin if his, Nadia, Salman Khan distributed Math video tutorials on YouTube. In 2009, the popularity of these videos and the testimonials of appreciative students prompted Khan to quit his job in finance and focus on the tutorials.
