Less than 3 percent of the population subscribe to music services provided by cable or satellite. Not much of a contest here. Competing successfully in today's commercial radio marketplace is fundamentally about choosing and executing a programming format that appeals to a large enough audience so that advertising will be effective. Compelling programming begets ratings. Ratings beget revenue.
Revenue begets profits.
Profits beget sustaining a business so that employees and shareholders can be paid. Radio economics 101. Even most NCE stations which have to generate underwriting dollars and live within a budget have figured this out. Formats which feature too much variety have historically been losers. They prefer familiarity and consistency yet not too much predictability.
