Lumen had turned over its catalog of “community-created course content,” it became clear, to Course Hero, Inc., the edtech “unicorn” and homework help site. The content wasn’t sold, the hosting was just handed off to free up resources, according to Lumen. In May, Course Hero quietly began putting the content on its site. The result is that clicking on a course content listing from Lumen—whether it’s “Boundless Accounting” or “African American History and Culture” or another course—will likely send you off to Course Hero, where it’s being hosted.
