i wonder what would happen if HBO applied this model? I mean they give away a free 2 week trial. Then you pay like 15 for so many channels. Every month they change about 50% of their programming to new programming. So in this model it would make sense to charge say an extra $5 a month. Pretty soon just HBO would cost as much as cable itself. 15 + 5 + 5 + 5 + 5 + ..... + 5

Where do you stop?
