These free online educational resources are also helping to break down the financial and geographical barriers that can limit access to education. "At some level, these courses are helping to democratize knowledge," says Dan Colman, the associate dean and director of the Stanford Continuing Studies program. "Suddenly, knowledge that was fairly specialized is available to anyone with Internet access. It doesn't matter how much money you have or where you live; it's accessible now."

Corrected on 02/17/10: An earlier version of this article incorrectly stated the number of videos offered on Academic Earth. The correct number is 3,500 videos. Additionally, the earlier version may have given an incorrect impression about the source of Stanford’s free online courses; many programs at Stanford contribute to the university’s free courses on the Web.
