Is it true, that if the stadium in a NFL game isnt sold out, the game wont air on the local TV?That is correct. It's called a "blackout".
So what exactly are the blackout rules?The short answer: If a game doesn't sell out within 72 hours of kickoff, there is no local television broadcast. "Local" in this case is defined as anywhere within 75 miles from the stadium. If a station from outside that 75-mile zone has any part of its coverage area crossing over, it gets blacked out too. This is why virtually all of Arizona, for instance, gets blacked out of Cardinals games. If a team comes close to selling out, the NFL can grant a 24-hour extension.
