Like Steve said, online does not mean "fake". In fact the relatively well known Harvard University has an online degree that is anything but fake. (note the sarcasm please). Some other famous schools with online programs/degrees or offerings: Notre Dame, Cornnel, Duke, LSU, University of Texas, University of Tennessee, University of Florida, multiple Cal State Schools, OU, NYU, Stanford, the list can go on and on.
I assume you've heard of some of these schools
