If I were Apple I think I'd do this... Get a ton of channels that require cable subscriptions on the AppleTV to get a census of who uses what channels and then after I had a good selection of "channels" create my own cable service and allow subscribers to login with the $30/month iCloudTV (or whatever) instead of Comcast, Uverse, etc.
How does one connect with iCloudTV if not through Comcast, Uverse, etc (broadband pipes)? So even if that would happen, the Comcasts, etc will just make up for the losses with higher broadband. Net result is that we pay more to basically cut Apple in.
And the whole model "as is" revolves around consumer desire for favorite channels driving the bundled family of channels. None of the players want to go to a model where only the jewel channels of their respective bundle are available for cheap. By pushing additional channels with their jewels, they can make all this subsidized revenue from commercials running on those other channels.
The best way to get our favorite channels without killing the golden goose of the subsidy is to use the "FAV" channel feature in on-screen guides to hide the 190 channels "we don't want" and only display the 10-20 channels we do want. Then the commercial subsidies generated by commercials running on the 190 channels still flow but we won't ever even see those channels in our FAV guide.
This perception that each channel available is actually costing us consumers something is wrong. All those other channels we don't want generate revenue to help pay for the channels & content we do want.
If we really want an al-a-carte, or a commercial-free, al-a-carte option, all we have to do is to get the masses to want it so much they'll pay more for it. As soon as it's more profitable to change the "as is", it will quickly change.
Else, if we want to believe that buying individual channels will cost less than bundles of channels, we should face the reality that everyone else in the chain wants to make MORE money, not less. SO, some kind of al-a-carte channel price modeling would be such that the 10-20 channels we really want will end up costing more than getting the same 10-20 channels with the 190 channels in the "as is" model. In other words:
200 channels for $75 OR
15 al-a-carte channels for $100.
AND, if the cable companies have to take the hit because it's an Apple that is going to take their cableTV revenues, expect broadband rates to rise to make up for their losses. So again, all that really happens here is that we pay more to cut Apple in. The content creators will not eat our big discount. Cable (who is also broadband) don't have to take the hit. Apple will want to pile on top and get theirs. We're all that's left.
