When I was younger, I heard a lot about mail order diplomas. Where you earned a degree by correspondence courses, and the quality was not there. The challenge for online degrees, which have replaced correspondence courses, is how do the demonstrate the quality of their output?
 Accreditation seems to a way.

Good article that touches on some of the challenges:
