Nexstar wants more money.

Nexstar pulls or threatens to pull their stations from the customers of TV providers to increase fees for stations far beyond their value. They’ve done it to Cox Cable, DISH, and Charter Spectrum, and now they’re doing it to us.
The four major broadcast networks (ABC, CBS, FOX, and NBC) have together lost about half their primetime audience over the past few years. Despite this, Nexstar is demanding the largest increase that AT&T has ever seen from any content provider.
It takes two to tango. If AT&T accepts the price increase, they'll have to pass it along to their customers, won't they. If these stations are simultaneously losing market share, the price should be decreased, not increased.
