According to EETimes, MIT is planning on putting its entire 1800 course curriculum online for free by the end of the year:

On Tuesday, school officials revealed plans to make available the university's entire 1,800-course curriculum by year's end. Currently, some 1.5 million online independent learners log on the MIT OpenCourseWare (OCW) site every month and more than 120 universities around the world have inaugurated their own sites for independent learners. MIT has more than 1,500 course curriculums available online to date.

Who are MIT's independent learners? One MIT calculation found that 17% were educators elsewhere, 32% students everywhere, and 49% were self learners. Other learners come from nations all over the world, from Antarctica to Darfur. He notes that the highest traffic in the United States comes from leading high-tech states Massachusetts and California. South Korea has a sizable base, accounting for a higher number of learners than, for instance, in China, its neighbor. Many learners are college teachers and professors, who want to sharpen their own teaching courses and methods. In a typical example, physics professor Younes Attaourti of Marrakesh, Morocco, has used MIT materials for his courses on statistical physics and quantum theory.
