I think the original post makes a good point. Folks are trying to claim that what Dish is doing is the industry standard, but the fact is that if you go out and get cable's rough equivalent of 120+, you get Versus, you usually get MSNBC (Not in all markets anymore, but still the majority I'd say), and you get some other essentially "standard" channels that Dish pushes up to higher tiers. Cable has digital tiers and such with higher costs, too, but usually they are for fairly specialized channels or premium movie channels.
The closest thing to a standard channel the majority of cable lineups push to a higher tier is the NFL Network. And even that is fairly specialized -- a channel all about one particular league in one particular sport with only eight live games a year.
