Apple has had an extremely inexpensive AppleTV product for watching TV shows and movies, listening to music, etc. on your HDTV set out for half a decade. Analysts continue to forget to mention that.http://www.pcmag.com/article2/0,2817,2400946,00.asp
While they are doing that, they obsess over the fact that Apple does not make a television set, while ignoring you can go out and buy an inexpensive little device (EyeTV) from El Gato that plugs into your Mac's USB port and gives it a TV receiver, turning it into a big television set.http://www.elgato.com/
The EyeTV also provides a way to monitor record your TV shows using a schedule you set up and maintain. That lets you record shows that air when you are asleep or away instead of missing them. It is far easy to use than VCRs. It not only makes your Mac into a TV but a DVR as well.
You use this device through a Macintosh application that comes with it. They also make an iOS application available for playing back the shows and watching the live TV on your iPhone, iPad, or iPod Touch.
