Santa Clara is launching an online MBA.

Then, there are these, all within less than a year:

That's a lot of new programs! What's worrisome is that they all kinda look the same. Click through to some of the program pages, and there seems to be hardly any differentiation between some of them. And still, these programs are not inexpensive: that new Santa Clara program, if I'm doing the math right, is more than $70k.

It's like they're not even trying.

I realize that these programs are low overhead and don't cost as much to administer as an in-class program. But I'm wondering at what point does this turn into a glut? For people who want to do an online MBA from a US school, I'm hard pressed to suggest anything other than the Nebraska-Lincoln program or the Illinois MBA. With the price points of those programs - and the fact that there's barely any differentiation among the competing programs - I'm wary of even suggesting IU Kelley's or UNC's Online MBAs - two long-standing MBAs that are probably great in their own right but don't seem to offer anything 'above and beyond.'

Am I missing something?

If a school can get the marketing right and the learning experience then there is certainly room. Many people all over the world value an MBA from a private US university but cannot afford to leave their jobs. The FT rankings show that state universities like Warwick, Massachusetts, and Nebraska deliver excellent outcomes, so they don't need to be too different. However, as the failure of Imperial College's initial online MBA shows, you need to work to get success.

Many of these schools are in any case digitizing courses for allow them to better support full-time and executive programs. As long as the demand is there, these small programs won't canibbalize their core market but they can help with future declines in demand for the US full-time MBA..

I think that schools with strong name brands will pull through. People want to have brands like Carnegie Mellon, USC, etc. on their CVs. I think the smaller schools will only be relevant regionally, or if they can offer accredited MBAs at a discount.
