Some of the early versions of online courses like OCW weren't actually intended to be used "out of the box" as courses though. They were explicitly intended to be resources that teachers could use and adapt to create courses tailored to the needs of a group of students. (I'm not sure how much actual cross-pollination there was, but OCW would seem to have grown out of some of the same thinking as One Laptop per Child.)

As it turned out, OCW ended up overshadowed by the various straight to consumer MOOCs.
