When it comes to sports media, a lot has changed since the days of radio being the only way of carrying games. Now teams can stream games which allow them to own all the advertising inventory and track with far more detail than radio, who's listening/watching (aka analytics). This is all especially true if you have your own app built. An app allows for targeted visual advertising, along with live reads during the game. Previously, many small AA and AAA teams had to give away most, if not all the inventory to the local radio station.
Expect the more well heeled and popular High School Football teams to head in this direction too. Especially in Southern cities.
