(Taylor, Communication 56, 59).
The subliminal advertisements took place in a movie theater located in Fort Lee, New Jersey where the phrases, "Drink Coca-Cola" and "Eat Popcorn" flashed on the screen while the movie was playing. More than 45,000 people were in attendance for the six weeks the experiment took place. The purpose of this experiment was to increase the sales of these two items at the theater's concession stand. As a result, sales of soda soared by 57.5% with popcorn sales increasing by 18.1%.
This experiment applies to the first approach to subliminal perception. This approach states that the constant repetition of very weak stimuli has an increasing effect on the consumer. This process allows stimuli to gain response to strength over more presentations or advertisements. This would be referred to as the operative theory, which becomes effective when weak stimuli are consistently flashed on a movie screen, such as Vicary's experiment performed in Fort Lee, or stimuli played repeatedly on a cassette (Haberstroh, 41).
Following these incidents, the National Association of Broadcasters prohibited subliminal messages to occur while a movie was in session. In 1962, Vicary claimed in an interview with the magazine Advertising Age that the original study never happened in the first place. The research and the results from the movie theater were never reproduced or documented following the experiment. People believed, however, that the events did take place and that the messages did appear while movies were in progress. .
Because of the fishy way Vicary documented his research and later denied even conducting such a study, his experiment became the first large subliminal scare. The results this study yielded are still commonly referred to as proof of how dangerous and influential subliminal projection really is (Shiffman, 158, 162). .
Key's Subliminal Paranoia .
In 1973, Wilson Bryan Key's book entitled, Subliminal Seduction was charged with the widespread use of hidden messages and images in print ads, which caused increased consumer retail.
