Sunday night CNN had a brief feature on Joseph Gordon-Levitt. It seems he's a co-founder of something called HitRecord and it has just teamed up with MasterClass, so they did the little segment about it.
I Googled HitRecord and here are two blurbs about it:
"HitRecord is an online collaborative media platform founded and owned by actor and director Joseph Gordon-Levitt. The company uses a variety of media to produce such projects as short films, books, and DVDs."
and
"HitRecord is a collaborative media platform that lets anyone work together on creative projects. If a project earns money, contributors are paid based on any work that makes it into the final product."
