Apple TV

The Apple TV, stylized as  tv, is a digital media receiver developed and marketed by Apple Inc. It is a small form factor network appliance designed to play IPTV digital content originating from the iTunes Store, Netflix, YouTube, Flickr, MobileMe, MLB.tv, NBA League Pass 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. It initially shipped with a 40 GB hard disk; a 160 GB version was introduced two months later and the earlier model was ultimately discontinued. Apple tv as to version, one version is apple tv 1 and 2. In September 2010, Apple announced a second-generation version of the Apple TV. About one 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. The second and third generation Apple TVs lost the hard drive; however, they did have an undocumented internal 8 GB flash storage, speculated to be used for smoother playback of streamed media. All content is drawn from online or locally connected sources. At a media event on September 9, 2015, Apple introduced the 4th generation Apple TV. This new model introduced a brand new operating system based on iOS known as tvOS, a new remote featuring Siri, and a brand new App Store. The new Apple TV costs $149 for the 32GB model, and $199 for the 64GB model.

First Generation
This generation has both HDMI and video out, unlike all other generations.

Second Generation
This model dropped the video out ports so it can be smaller. It is one quarter of the size of the previous generation.

Third Generation
This generation has the exact design as the previous generation. It supports 1080p video content.

Fourth Generation
The 4th generation Apple TV, announced on September 9th, introduced tvOS and the Siri Remote, as well as a design that is slightly taller than the previous generations.
