Not surprisingly, the Fire TV is very tightly integrated with the Amazon Instant Video service. But there are tons of other content providers that work with it including Netflix, Hulu, HBO GO and HBO NOW, Sling TV, ESPN, Disney, PBS, History, YouTube, NBA, and many more.
Note: Buying an Amazon Fire TV does not give you access to the content you can watch on it, just like buying a TV does not give you access to cable TV shows. You need to have accounts with each service that provides the content (some free, some paid) and/or subscribe to a cable/satellite package that gives you permission to access shows from specific networks through the Fire TV. When you see an app listed as “free” on the Fire TV interface or the Amazon website, it just means there’s no cost to install the app itself on your player. It has nothing to do with whether the content accessed by the app costs money.

The Fire TV supports lots of music services as well, including their own Amazon Music, Pandora, Spotify, and iHeart Radio.
