Good Lord, what a time when networks used to PAY affiliates to run their programming....
When exactly did the tide shift from actual to reverse compensation? Retransmission Consent and Must-Carry rules debuted in 1993 and the only deals at the time were between corporations and their "sister" cable channels in the few places they overlapped. As companies consolidated, these overlaps became more common.
KRON getting bought by Young was the lynchpin of the modern arrangement since NBC enacted onerous demands they did not want to follow. So they took their ball over to KNTV to rechristen themselves as NBC for the Bay Area. Other stations like WJXT and WISH followed because they either did not want to pay for network programming, or balked at the rate that they were being charged for network programming.
And then, Perry Sook decided to shake down the cable companies at the source, demanding cash for the carriage of Nexstar's stations. Then the networks wanted their cut of this, and our jacked up form of paying for free TV exists to this day, but for how much longer?
And most of the defections in recent years? CBS. Because they wanted more money.
CBS shot themselves in the foot in Raleigh to get Media General / Nexstar to pay them more $$$. NBC gets on WRAL and runs with it since it's their best ratings EVER there.
And with what just went down in Atlanta, they'll take their ball and go home where they can when it's not working.
