Streaming Services
If you intend to use feature films in your class, you might consider asking your students to pay for content from a streaming service such as Netflix, Hulu, Amazon Prime, among others. Many distributors and filmmakers also make their titles freely-available on Vimeo, YouTube, and other sites.
Streaming Aggregators
Aggregators can make finding movies and shows online easier. Not every aggregator has listings from all the different providers (Hulu, Netflix, Amazon, Vudu, ABC, Fox, etc.) so it is useful to check several when you are looking for a particular title.
