Many things are possible in advertising which are too costly to attempt. That is another reason why every project and method should be weighed and determined by a known scale of cost and result.

Changing peoples habits is very expensive. A project which involves that must be seriously considered. To sell shaving soap to the peasants of Russia one would first need to change their beard wearing habits. The cost would be excessive. Yet countless advertisers try to do things almost as impossible. Just because questions are not ably considered, and results are traced but unknown.

For instance, the advertiser of a dentifrice may spend much space and money to educate people to brush their teeth. Tests which we know of have indicated that the cost of such converts may run from $20 to $25 each. Not only because of the difficulty, but because much of the advertising goes to people already converted.

Such a cost, of course, is unthinkable. One might not in a lifetime get it back in sales. The maker who learned these facts by tests make no attempt to educate people to the tooth brush habit. What cannot be done on a large scale profitably can not be done on a small scale. So not one line in any ad is devoted to this object.

This maker, who is constantly guided in everything by keying every ad, has made remarkable success.
Another dentifrice maker spends much money to make converts to the tooth brush. The object is commendable, but altruistic. The new business he creates is shared by his rivals. He is wondering why his sales increase is in no way commensurate with his expenditure.

An advertiser at one time spent much money to educate people to the use of oatmeal. The results were too small to discover. All people know of oatmeal. As a food for children it has age-old fame. Doctors have advised it for many generations. People who don’t serve oatmeal are therefore difficult to start. Perhaps their objections are insurmountable. Anyway, the cost proved to be beyond all possible return.

There are many advertisers who know facts like these and concede them. They would not think of devoting a whole campaign to any such impossible object. Yet they devote a share of their space to that object. That is only the same folly on a smaller scale. It is not good business.

No one orange grower or raisin grower could attempt to increase the consumption of those fruits. The cost might be a thousand times his share of the returns. But thousands of growers combined have done it on those and many other lines. There lies one of the great possibilities of advertising development. 

The general consumption of scores of foods can be profitably increased. But it must be done on wide co-operation.
No advertiser could afford to educate people on vitamins or germicides. Such things are done by authorities, through countless columns of unpaid-for space. But great successes have been made by going to people already educated and satisfying their created wants.

It is a very shrewd thing to watch the development of a popular trend, the creation of new desires. Then at the right time offer to satisfy those desires. That was done on yeast’s, for instance, and on numerous antiseptics.

It can every year be done on new things which some popular fashion or widespread influence is brought into vogue. But it is a very different thing to create that fashion, taste or influence for all in your field to share.
