Subliminal perception is a subject that virtually no one wants to believe exists, and -- if it does exist -- they much less believe that it has any practical application. . . . The techniques are in widespread use by media, advertising and public relations agencies, industrial and commercial corporations, and by the Federal government itself.

Merchandisers, by embedding subliminal trigger devices in media, are able to evoke a strong emotional relationship between, say, a product perceived in an advertisement weeks before and the strongest of all emotional stimuli -- love (sex) and death.
