There are many sources for streaming video content available that students can access on their own. For instance, subscription services Netflix and Hulu offer thousands of documentaries, mainstream film titles, and television programs on a streaming basis for an affordable monthly fee that most students likely already pay. Additionally, sites like Amazon and iTunes offer inexpensive streaming video rental. Instructors are encouraged to investigate availability of videos through these subscription services that they wish students to view and require students, as part of the class, to have one of these low-cost monthly services or to rent movies on their own time. .

You may search or browse for films by title or genre. On some pages, you may filter by MPAA ratings, copyright year, and genre.
On the homepage, use the search bar at the top to search for keywords in the title or description.
Use the Advanced Search page to search for keywords and/or search by Producer, Copyright Year, Genre, or Language (there are a few Spanish-language films and several with Spanish subtitles). Other advanced search features listed don't actually provide additional functionality.
Copyright determines what may and may not be used in the classroom. Films may be shown synchronously in a closed classroom (or behind the portal), if you only use what is pedagogically necessary. When you download a link to your Canvas shell, you are making a copy. This breaks copyright law.
Service Agreements are usually more restrictive because those services either own their own original content (Amazon or Netflix) or have paid a licensing fee to the copyright owner to show that film. When you download a film for a non-personal use, you are breaking the service agreement. While the worse thing that will probably happen to you is your service will be cancelled, do you want to chance it.
