After commemorating its 10th anniversary in September, MIT OpenCourseWare is now celebrating another historic achievement. The open-source platform not only set an annual record in 2012, but an all-time record in January, seeing groundbreaking growth in the face of rising massive open online courses.

OpenCourseWare received 22.3 million visits from 11.8 million visitors in 2012, according to a recent blog post. With free materials from 2,150 MIT courses, the team estimates they have reached about 150 million individuals worldwide since debuting 10 years ago.

In January alone, OpenCourseWare saw 2.25 million visits from 1.3 million unique visitors.

“That’s truly a level of usage unimaginable when MIT set out to create OCW, and we are humbled to have touched the lives of so many,” writes External Relations Director Steve Carson.

OpenCourseWare transformed education, inspiring more than 250 universities across the globe to make their core materials available for free. An increasing amount of online platforms offering free courses have also debuted, including Coursera, Udacity and Khan Academy.

Since October 1, 2003, the team says OpenCourseWare has:

  • Received more than 120.2 million visits from 74.4 million unique visitors
  • Received more than 786.7 million page views
  • Received more than 1.8 million visits from the MIT community
  • Recorded more than 40 million downloads from [its] iTunes U channel, and
  • Recorded more than 40 million views of [its] videos on YouTube.

And as online education continues to grow in popularity–more than 6.7 million students are now taking at least one online course–those numbers are only expected to break new records.
