Presumably you want finer-grained a la carte, like individual shows and movies. You can get that today via iTunes but it is insanely expensive, and it doesn't really make economic sense because not enough consumers watch little enough TV for that to make sense, therefore the price remains high and companies offering it are not doing well.
Right now the market forces are pushing everyone to try to be either Netflix (streaming service become producer) or HBO (producer becoming streaming service). As the technologies commoditize this trend will continue, and consumers will just have to deal with the abominable UX that this balkanization of services creates. It'd be nice if someone could wrap a nice UX around this, whether it be a la carte or whatever, but I don't see that market forces would allow that, and least not until the balkanization gets a lot worse and rights holders get an incentive to play nice with aggregators.
Cable companies and centralized distributors are the natural conclusion of our copyright mechanisms. Online video has already been coalescing on Netflix and Amazon as the next-gen cable cos instead of Comcast and AT&T.
If we don't want to be stuck with the same thing over and over again, we need to change the way that we've constructed the artificial market for intellectual goods, so that subscription bundles a la cable is no longer the only feasible economic model.
Seeing as that's the problem, affording agents in the space more or better control to try and strengthen the market could be an approach - so I want to understand where/what the current weaknesses are.
The hope always seems to be to operate like a gym, where there are people paying but almost never showing up.
1) Buy individual episodes
2) Buy individual season
3) Buy individual channels (FX, HBO, with ESPN and Disney coming soon and more and more networks offering this option)
4) Buy bundles of content (cable, Netflix, Hulu, etc.)
Availability windows also seem to be designed to match consumers demands, you'll pay more to get copies of episodes right away vs waiting a season or two to buy them.
Again, I think it's fair to find the prices to be greater than what each individual is willing to pay, but I don't think the actual options are lacking in the same way they were 3 years ago.
That's all going to consolidate into the hands of a couple of major producers (Disney, HBO, Amazon, Netflix, maybe Hulu) and that's about it.
NBC/Universal/Comcast Viacom Fox Sony Time Warner BBC
Plus some other deep pockets who are slowly getting in the game (Verizon, AT&T, Apple)
I think there'll be enough competition even among the oligopolies to make it palatable for consumers.
This however creates the incentive for providers to start enforcing long term contracts for the regular price, or a much higher price for a monthly plan, in which case DVDs will be relevant again for me.
I don't want to have an HBO account, and a Disney account, and a Hulu account, and a Netflix account, and an Amazon account, etc etc. I wish they'd play nicely and let one provider bill me, and take care of restricting my access to their HBO portion of their library unless I pay an addition $X/month.
