Apple TV gives you anytime access to endless entertainment. Thousands of HD movies and TV shows from iTunes — many in stunning 1080p — play through Apple TV on your HDTV, and music and photos stream from your computer. You just click and watch. With AirPlay, it’s simple to play content from your iPad, iPhone, or iPod touch on your TV.1 And the Apple TV interface makes it easy to find whatever you’re in the mood for.
Apple have made three generations of Apple TV.
The first generation contained a hard drive and worked in a similar manner to an iPod.
The second generation was smaller, had no internal storage (that could be used) and worked by streaming content either from a Mac on your home network or from the cloud.
The third generation was similar to the second generation, but could stream 1080p content.
