What is an Area Of Dominant Influence (ADI)?
The main Area Of Dominant Influence (ADI) is the geographical area or market accessed by a specific radio or television station. It is used by advertisers and rating companies to identify the station’s potential audience. This will help in determining how much the songwriter will be paid to broadcast on a given station.
For example, New York, Los Angeles, and Chicago topped the Marketing Systems Group list in the early 2000s, while smaller cities such as Montana (Helena), Nebraska (North Platt), and Michigan (Alpina) represented the other side.
