I don't know any official rules on that kind of stuff, but here's a site that links to a map for each week, that shows which game is shown where each week, which you might find interesting.I am kinda curious, how does it work if you live in a state without a NFL team? I know some teams have "territorial" rights in states based on locations if there's more than 1 team, but if you live in like Montana, do you just get whatever the slate of games are for the week? Or do certain teams have priority on states they're not in for broadcasting?
For example, Montana got these games so far this season (I excluded the ones that got shown in like 90% of the country):
Week 1: Tennessee @ Kansas City, Minnesota @ St. Louis
Week 2: New England @ Minnesota, Kansas City @ Denver, Seattle @ San Diego
Week 3: Houston @ NY Giants, Green Bay @ Detroit
Week 4: Carolina @ Baltimore, Philadelphia @ San Francisco (west montana)/Atlanta @ Minnesota (east montana)
Week 2: New England @ Minnesota, Kansas City @ Denver, Seattle @ San Diego
Week 3: Houston @ NY Giants, Green Bay @ Detroit
Week 4: Carolina @ Baltimore, Philadelphia @ San Francisco (west montana)/Atlanta @ Minnesota (east montana)
So it seems Montana gets the most preference to KC and Minnesota.
