but what exactly do these apps give you that you are not already getting if you already are using a cable TV provider?...you still need to have a cable sub to activate most of these apps right?...or you need to pay for a subscription service like Netflix...I mean it's not like these apps are free on the ATV/Chromecast etc
Catalogues of back episodes that you can't get via the on demand service. Like through the Disney app or Nick app or others. New apps are released or updated all the time.
