We have to go back several decades or more to remember when All In the Family and N.Y.P.D. Blue were not carried by a number of stations that felt they were inappropriate for their markets. They did not lose their affiliate agreements.
Actually, it was those pre-emptions which were a big part of the reason the pre-emption provisions in affiliation contracts were strengthened.
What happened with those two shows, from 1971 and 1993, is mostly irrelevant under the contracts in force now, 30 to 50 years later. The provisions weren't there back then to cause a possible breach of contract. Today, they are.
Similarly, in the first decades of TV and before each market had at least 3 TV stations, stations often shared two or even three of the networks, meaning that a lot of shows did not run in those markets.
That was a situation unique to the early days of the medium, secondary affiliations were common in those markets, and the networks could only hope for clearances ... they were not in any way guaranteed by the affiliation contract terms the way they are now.
Again, citing "the way it was back then" is irrelevant to the present discussion.
