This site is loaded with resource materials on various aspects of social media. At this link, one can click around and find “Fair Use for Open Courseware”…which kind of fits what PSA is trying to work on. The big question here is how much of film and video “clips” can be “used or repurposed” for training courses, or educational courses.
