In the advertising industry, it’s known that three time exposure to the advertising message delivers about 5% response from your targeted audience. Therefore the return on advertising investment can be fairly well calculated in an established enterprise.
So, for example if a seated President had a non-biased media network and a message that already resonates with many, a complete turnaround in acceptable thinking could be accomplished in a short amount of time. Depending on which five percent you are targeting, that five percent is enough to right this ship of State. In the case of an already popular President, the swiftness of the turnaround could be measured in days, even as little as three.
