A common complaint about cable isn’t the lack of channels; it’s the lack of things to watch. To get the three channels they actually want, consumers also have to accept 497 channels they’re never going to watch. Amazon Prime seems to be in the early stages of trying to fix that, though, as its new Streaming Partners Program will allow members to add subscription programming from nearly 20 channels for an additional fee. People can choose the channels they want, switch them in and out from month to month, and have access to their programing through Amazon Prime’s interface.
