"While the nominal price of basic cable service has been increasing over time, the dramatic increase in the amount of time cable subscribers spend watching basic cable networks is compelling evidence that the quality of basic services has been increasing as prices have been going up. The real (inflation-adjusted) price of cable service divided by the number of hours spent watching basic cable programming is an appealing measure of changes in the quality-adjusted real price of basic service because it reflects both changes in the price of service and viewer responses to changes in service quality over time."
