I don't understand why getting channels a la carte is "the TV holy grail". Just because you like one program doesn't mean you like the rest of what a channel shows. To me it's the same problem as paying for channels you don't like, just at a different scale. I want to pay for the programs I want. Which you can currently do, sort of. I just want to be able to do it for all programs. And I want discounts for paying in bulk (full season) and for paying in advance.
