Years ago I dated a woman who worked for WOW (Wide Open West) cable. She said that every now and then her company flirts with the idea of "Ala Cart" Cable TV, where you would pay 50 cents (local network channels for example) or 1.00 dollar a month for JUST the channels you want, kinda like buying an I-tune. If you wanted multiple hundred channels, you'd pay premium dollars, but if you're like me, and would be happy with 10-20 channels you'd pay less. Premium channels like hbo would be higher of course.
She said unfortunately as much as tons of customers would jump on it, that noone would be the first company to go that route. And besides, they make too much money with the high monthly package.
But she said, that now that cable's digital, the technology to actually do that is here.
I'd be totally happy to pay 30 bucks a month for 20-25 cable channels like History, Discovery, Food Network, Cnn, Scifi and a select few others along with my local networks.
