The FireTV is Amazon's set top box, used for streaming movies, playing music and enjoying games and designed to sit next to your television. There are two versions of the FireTV.
One (called simply 'FireTV') is a small set-top box, which sits in your entertainment center and has a cable to plug into your TV. The other (called 'FireTV Stick') is about the size of a USB Flash drive, and plugs into the back of your TV. There are two versions of the stick. For the most part, all of these devices support Alexa. The only one does not is the first generation FireTV Stick. If you have one of those original FireTV Stick's, you can purchase a remote control with voice capability. Read More >>> about How to Use Alexa on your FireTV
