Scenario 15-7
Black Box Cable TV is able to purchase an exclusive right to sell a premium movie channel (PMC) in its
market area. Let's assume that Black Box Cable pays $150,000 a year for the exclusive marketing rights to
PMC. Since Black Box has already installed cable to all of the homes in its market area, the marginal cost of
delivering PMC to subscribers is zero. The manager of Black Box needs to know what price to charge for the
PMC service to maximize her profit. Before setting price, she hires an economist to estimate demand for the
PMC service. The economist discovers that there are two types of subscribers who value premium movie
channels. First are the 4,000 die-hard TV viewers who will pay as much as $150 a year for the new PMC
premium channel. Second, the PMC channel will appeal to 20,000 occasional TV viewers who will pay as
much as $20 a year for a subscription to PMC.

of delivering the sports channel to subscribers is zero. The manager of Mega Media needs to know what price
