Refer to the scenario. OrangeTV is able to purchase an exclusive right to sell a premium sports channel (PSC) in its market area. Let's assume OrangeTV pays $100,000 a year for the exclusive marketing rights to PSC. Since OrangeTV has already installed cable to all of the homes in its market area, the marginal cost of delivering PSC to subscribers is zero.
