It is indeed a “thing”. In the 1950s NFL teams sold their media rights separately. They had to get an anti-trust exemption from the government to sell the whole league as one package.
This is known as the Sports Broadcasting Act of 1961, It effectively prohibits games all day Saturday or after 6 (local) Friday before the 2nd Sunday in December.
The NFL is going to the well too often with off-time games. Not only does it dilute ST, it dilutes the Fox and CBS packages, because every time the local team in City X doesn’t play on Sunday afternoon is another Sunday afternoon where interest in the NFL is lower in City X.
Baseball: No. And its on Apple, not Amazon.
Football: It is the NFL’s longstanding practice that games not show on OTA TV, be that ESPN or now some streamer, are shown on an OTA station in the two cities (for the Packers both Milwaukee and Green Bay count) where the teams are located. So, for example, if the Bengals were playing on Amazon or ESPN, they would be on a station in Cincinnati. But not places like Lexington or Dayton or Columbus.
Apple, not Amazon. And, no. Apple produces 2 games each Friday night. These are ONLY on Apple TV +, nationwide. Since every team plays on Fridays, the remaining 13 games are shown as normal.
So, last Friday, one of the Apple games was Cardinals @ Reds. This game was only on Apple TV +, nationwide. But the Guardians played at the Yankees. That game was shown in the Cleveland area on Bally Sports Great Lakes, in the NYC area on YES, and in the rest of the country on MLBEI and mlb.tv subscription services.
