Apple TV is Apple's digital media receiver designed to play IPTV digital content originating from the iTunes Store, Netflix, YouTube, Flickr, MobileMe or any Mac OS X or Windows computer running iTunes onto an enhanced-definition or high-definition widescreen television.
Apple offered a preview of the device in September 2006 and began shipping it the following March. But, Apple discontinued the earlier version of Apple TV.
In September 2010, Apple announced a second-generation version of the Apple TV. About a quarter of the size and one-third of the price of the original Apple TV, the new device can stream rented content from iTunes and video from computers or iOS devices via AirPlay.
