A short history of open courseware
How universities started publishing their teaching for everyone.
In the early 2000s several universities decided to publish course materials online for free. MIT OpenCourseWare, launched in 2002, became one of the largest such collections.
Open licenses such as Creative Commons made it possible for anyone to reuse and share those materials, as long as they credit the source and do not sell them.
Today millions of learners use these recordings. Projects like ours exist to make them easier to find and follow.
