10) Scenario 15-8
Mega Media Cable TV is able to purchase an exclusive right to sell a premium sports
channel in its market area. Let's assume that Mega Media pays $100,000 a year for the
exclusive marketing rights to the sports channel. Since Mega Media has already
installed cable to all of the homes in its market area, the marginal cost of delivering the
sports channel to subscribers is zero. The manager of Mega Media needs to know what
price to charge for the sports channel service to maximize her profit. Before setting
price, she hires an economist to estimate demand for the sports channel. The economist
discovers that there are two types of subscribers who value premium sporting channels.
First are the 3,000 die-hard sports fans who will pay as much as $150 a year for the new
channel. Second, the premium sports channel will appeal to 20,000 occasional sports
viewers who will pay as much as $25 a year for a subscription to it.
How much profit will Mega Media Cable TV earn if it sets the price at $150?
a. $350,000
b. $450,000
c. $475,000
d. $575,000
