Why Do Cable Companies Pay ESPN?
Ben Gilbert and David Rosenthal say ESPN invented a second revenue line for cable networks: the affiliate fee. Before ESPN, channels showed up in the bundle and lived on advertising, and some startup networks even paid operators to be carried.
ESPN was buying sports rights and asked cable companies for cents per viewer so it could afford those rights. Sports then became leverage. ESPN could threaten to pull NBA, MLB, NFL, or SportsCenter, and angry subscribers would show up at the cable company. The fee climbed from a few cents to $1, then $2, then $5 a month. The average deal now is $9.42 per subscriber per month, by far the highest paid channel.
