YouTube's Movies & TV storefront (not to be mistaken with YouTube TV) allows you to rent and purchase thousands of films and TV shows. You can pick from the latest blockbuster releases, foreign films, award-winning staples, beloved classics, and even pre-order titles that have yet to be available elsewhere. A big draw here is that YouTube is already everywhere—it's a tab on your browser, an app on your phone, a channel on your smart TV—so renting, purchasing, and later on accessing a title is as easy as entering your credit card or PayPal details. And as a bonus, YouTube also has a lineup of free movies it lets you watch with ads. Granted, they're not as big or new as their rentable titles, but there are gems like Moonstruck and Cooley High hidden in there somewhere.
Now, some things to note before heading to the storefront: you must be 18 years or older to watch these titles, and while buying a movie or TV episode allows you to access them indefinitely, you have only 30 days to start viewing a rental. Once you've started watching it, you usually have about 48 hours until it expires, but this can vary per title. YouTube also allows playback in HD and 4k, but these features are currently unavailable on web browsers.
