Why doesn every MIT OpenCourseWare course offer video lectures?
Where possible, we have included pre-existing video on this site, and we continue to invest in video recordings. Video, however, remains a supplement to our mission of publishing and updating core teaching materials. Video is among the most costly types of content to produce and distribute, and including more video would impact the depth and currency of the site, affecting the many other ways visitors use our material. At present our focus remains on making the courseware used in all MIT courses available as a resource to educators and learners around the world.
