10 schools with the largest online enrollments. Some of the names might surprise you https://finance.yahoo.com/news/10-schools-most-online-students-141653810.html
Those enrollment numbers are tiny. This cannot possibly be accurate. Also, it's missing some prime suspects, including the University of Phoenix.
The number of customers you have shows how good your product is. At least that's the theory. If these schools sucked, you'd think that people would go elsewhere.
Glad you mentioned that's in theory. I love my Liberty experience and would choose the school all over again. As far as reputation goes, UCF and ASU lead the pack.
This list is older, and it appears that it does not separate online from on-campus students, but it does include big online schools that weren't in the U.S. News list. https://collegestats.org/colleges/online/largest/
