A subliminal message is a message embedded in another medium designed to pass below the normal limits of perception. Usually, the messages are not readily recognized by the conscious mind, but in certain situations can and oftentimes do affect the subconscious mind. So, why do people use this messages? Ill explain it with a little example In Fort Lee, New Jersey, a movie theater ran the messages "Eat Popcorn" and "Drink Coke" every five seconds throughout the movies they showed. In six weeks, the sales of Coca-Cola went up 18 percent while popcorn sales rose an astronomical 58 percent.Why would moviegoers accept these advertisements and not simply storm out of the theater, annoyed and resolute not to purchase any soda or popcorn? The reason is these messages were only flashed for three-tenths of a millisecond, or one 3000th of a second, a time that does not allow the moviegoer to consciously "see" the message or in some cases its a really hidden message. Subliminal messages keeps our subconscious focused on the physical and superfluous - sex - money - mortality.
