Take the World's Best Courses, Online, FOR FREE!
Coursera is an education technology company founded by computer science professors Andrew Ng and Daphne Koller from Stanford University, located in Mountain View, California.
Coursera says it is "committed to making the best education in the world freely available to any person who seeks it". While Coursera is a for-profit company, they are not currently generating revenue.
As of August 16, 2012 more than 1,080,000 students from 196 countries have enrolled in at least one course.
Coursera was launched shortly after Udacity, a for-profit online education venture by former Stanford Professor Sebastian Thrun, and shortly before edX, a not-for-profit online education initiative by MIT and Harvard.
