Produced by: Richard Paul As was the case with virtually every industry during the dot-com craze of the 90s, it was once thought that university education would be revolutionized by the Internet. And just as with those other industries, the harsh economic light of the early 20th century, has revealed winners and losers.

Yet others -- including New York and Temple Universities have abandoned their for-profit on-line education initiatives as unviable, amid carping by faculty that the demands of on-line education were perverting the education process. A look at on-line universities, what they are, what they aren't and whether they can survive.
