I expect that the A La Carte cable system is simply another way to make more money. As to the various Televangelist channels, the true believers will pay if necessary to get them. They pay now by buying the videos, the sermons, the prayer towels and all the other stuff the televangelists sell.
There's no real difference between the Televangelist channel and the Shopping Channel, Ron Popeil's commercials or any of the other marketing channels. The Televangelist Channels exist to market their products. It's a very profitable business and if necessary, they will be more than happy to pay the cable systems for access. If that fails, they will but turn to direct marketing through the churches that supply their customer base.
