Sublminal

affecting your mind even though you are not aware of it

Ever been watching a movie and suddenly get the munchies? Or sitting on your sofa watching TV and suddenly get the irresistible urge to buy a new car? If so, you may be the victim of a subliminal advertising conspiracy! Proponents of this conspiracy theory include Wilson Bryan Key (author of "Subliminal Seduction") and Vance Packard (author of "The Hidden Persuaders"), both of whom claimed that subliminal (subconscious) messages in advertising were rampant and damaging. Though the books caused a public outcry and led to FCC hearings, much of both books have since been discredited, and several key "studies" of the effects of subliminal advertising were revealed to have been faked.

In the 1980s, concern over subliminal messages spread to bands such as Styx and Judas Priest, with the latter band even being sued in 1990 for allegedly causing a teen's suicide with subliminal messages (the case was dismissed). Subliminal mental processing does exist, and can be tested. But just because a person perceives something (a message or advertisement, for example) subconsciously means very little by itself. There is no inherent benefit of subliminal advertising over regular advertising, any more than there would be in seeing a flash of a commercial instead of the full twenty seconds. Getting a person to see something for a split-second is easy; filmmakers do it all the time (watch the last few frames in Hitchcock's classic "Psycho"). Getting a person to buy or do something based on that split-second is another matter entirely.
