You aren't advertising to a standing army; you are advertising to a moving parade. Three million consumers get married every year. The advertisement which sold a refrigerator to those who got married last year will probably be just as successful with those who'll get married next year. An advertisement is just like a radar sweep, constantly hunting new prospects as they come into the market. Get a good radar and keep it sweeping.
