So in the future, why do we even need channels, as they exist today, as we transition over to receiving all of our content online? Why do I need an HBO subscription when I really just want Game of Thrones? That's 12 hours a year of programming. Charge me $5 per episode and be done wroth it. Want to watch a NFL game? $10.
Let me go to GameOfThrones.tv or BreakingBad.tv and purchase what I want to see.
I could see subscription-based services like Netflix for old, archived shows in bulk but just let me buy the new releases that I want without subscribing to an entire channel that I don't want any other content from. That would be true a-la-carte service
I'd definitely save money buying new release shows episodically.
