Basically, a content provider -- some very good, some very mediocre -- and the content packager (who controls the a la carte prices) get together to fund a study to their mutual advantage: Disney gets to force lower-quality cable networks onto cable companies, who then force the consumer to pay for them via network packages. And the cable compnies don't have to change their pricing structure (that might involve a lot of work and a lot of pricing changes until equilibrium is established).
My take: yes, it's possible that some will pay more and some will pay less. That's not important, because people will pay what they want to and/or can afford to pay for TV entertainment.
More important (IMO) is that everyone should have more CHOICE in the matter of which networks to buy and watch.
No, I'm not concerned with some tiny cable network trying to gather market share. Most are backed by huge entertainment companies anyway. Am I supposed to be concerned that Oxygen goes out of business? (I don't think it will.) No. Oprah will be fine. The good programs on otherwise unwatched channels will be sold to channels that have more viewers. Worse ones will be traded down.
Just my opinion. I could be wrong.
I'd like my city council to force this on the local cable operator.
