In general, you cannot show films from Netflix, Hulu, Amazon Prime or other individual streaming services to your class or student organization.
Video streaming service licenses generally restrict use of their content only to individuals, households or informal gatherings of friends. In other words, you can watch one of their shows together with a group of friends, but you cannot show it as part of a class or as part of a student organization event.
Information about acquiring Public Performance Rights (PPR) for a film you wish to show or finding films that already have PPR is available through the Online Video Guide.
