You may not realize the largest local class providers in your area have existed for decades. They’re community & continuing education programs at community colleges.
In California alone, there are 113 community colleges in 72 community college districts. It is the largest system of higher education in the world, comprising 2.4 million+ students. (See also: California Community College Chancellor's Office (CCCCO))

For an instructor wanting to connect to a new audience, or an online learning provider/edtech company looking to cultivate meaningful inroads into higher education, this is the place to be.
