Futurist Thomas Frey: In 1997 Reed Hasting returned his copy of “Apollo 13” to the video store and was hit with a late fee so big that he was embarrassed to tell his wife about it.

As colleges try to deliver more education at the same price, schools will move into the crowded and distractable world of the Web.
