Persuasive advertising theory a century ago had marketers trying to reach consumers with the same message three times - the first to make them aware of the product or service, the next to build their knowledge of it and then the third to drive that consumer’s intention to buy it.
Take the marketing of wine in the first couple of decades of the 1900s. Penfolds is a great illustration. There are some terrific examples to be found in the various state library archives, all extolling the unequalled quality of the grapes and the wine itself. It was a single-minded message, delivered to the potential consumer along the various points of what was then a fairly simple path to purchase. Make the consumer aware of the wine via the print ad, remind them as they pass a billboard on the train on the way home, build their knowledge via reviewing the wine in the newspaper and sampling it at an expo, and then entice them to buy as they walk past a well-displayed store window.
