We are just beginning to understand the Natural Laws of advertising. Donâ€™t panic. They could have been written by Weight-Watchers. The first law seems to be donâ€™t pig-out. Moderation makes advertising work better. Consumer markets show decreasing marginal response to high levels of advertising. Each additional exposure contributes a little less, so shoveling-it-in in bursts or flights is not cost-effective. Weight-Watchers tells the planner to save some donuts for tomorrow.
The second law is donâ€™t skip dinner. More continuous advertising brings increasing marginal response. Each week added to a campaign produces more than the week before. Itâ€™s like compound interest. This means spreading the advertising across time is more cost-effective. Besides, not eating can give a brand a headache.
These two Laws teach the planner that more weeks of advertising are a better choice than heavier weight each week.
Third Law. Eat A Balanced Diet. Diminishing marginal response describes media as well as media weight, which explain the importance of media-mix.
