The Magic Number is 3.29!
Research (from analyzing thousands of advertiser schedules) has shown that the magic number of exposures is 3.29. That means that the
station's most dedicated listeners must hear your commercial at least 3.29 times before
acting upon your request.
How this works in the human brain:
1. First exposure: "What is it?"
2. Second exposure: "What of it?"
3. Third exposure: "Let's do it!"
Repetition is the key to learning and the key to advertising. Research points clearly to the fact that three exposures are the minimum level required for effectiveness.
