As of November 2007, over 1800 courses were available online. While a few of these are limited to chronological reading lists and discussion topics, a majority provided homework problems and exams (often with solutions) and lecture notes. Some courses also include interactive web demonstrations in Java or Matlab, complete textbooks written by MIT professors, and streaming video lectures.
As of August 2008, of the over 1800 courses available, only 26 included complete video lectures, and not all of these have complete lecture notes. The lack of lecture notes makes it difficult to follow some lectures, for example, when the lecturer is referring to slides being projected in the lecture hall. The selection of available courses is somewhat incomplete. For example, prerequisite classes for a given course are frequently not available. However, the quality of those courses which include complete materials is very high, and many of the lecturers are extremely compelling. The video is available in streaming mode, but may also be downloaded for viewing offline, though the procedure for downloading is not explicitly given. Many video and audio files are also available from iTunes U
The main challenge in implementing the OCW initiative had not been faculty resistance, but rather, the logistical challenges presented by determining ownership and obtaining publication permission for the massive amount of intellectual property items that are embedded in the course materials of MIT's faculty, in addition to the time and technical effort required to convert the educational materials to an online format. Copyright in MIT OpenCourseWare material remains with MIT, members of its faculty, or its students.
In September 2002, the MIT OpenCourseWare proof-of-concept pilot site opened to the public, offering 32 courses. In September 2003, MIT OpenCourseWare published its 500th course, including some courses with complete streaming video lectures. By September 2004, 900 MIT courses were available online. The response from MIT faculty and students has been very positive and MIT OpenCourseWare is seen as being consistent with MIT's mission (to advance knowledge and educate students in science, technology, and other areas of scholarship that will best serve the nation and the world in the 21st century) and is true to MIT's values of excellence, innovation, and leadership.
In 2005, MIT OpenCourseWare and other leading open educational resources projects formed the OpenCourseWare Consortium, which seeks to extend the reach and impact of open course materials, foster new open course materials and develop sustainable models for open course material publication.
Video content for the courses are primarily in RealMedia format. Though the default videos provided are meant to be streamed from the MIT server, they are also provided in full for offline downloads.
