James Vicary

James McDonald Vicary (April 30, 1915 – November 7, 1977) was a market researcher best known for pioneering the concept of subliminal advertising with an experiment in 1957. It was later suggested that the results of his experiments had been fraudulent. Vicary was unable to ever reproduce the results of his experiments.
Vicary himself admitted that he had never conducted the subliminal "experiment" — it was concocted as a gimmick to attract customers to his failing marketing business.
Biography.
Born in Detroit, and trained at the University of Michigan (A.B 1940), he pioneered the use of eye-blink analysis to obtain clues about subjects' levels of emotional tension when exposed to various stimuli. He also studied the phenomena of impulse buying and word association.
He was also known to have a childhood fascination with snakes. He was called Detroit's youngest snake charmer by the Detroit News.
He is most famous for having perpetrated a fraudulent subliminal advertising study in 1957. In it, he claimed that an experiment in which moviegoers were repeatedly shown 1/3000-second advertisements for Coca-Cola and popcorn significantly increased product sales. Based on his claims the CIA produced a report "The operational potential of subliminal perception" in 1958 that led to subliminal cuts being banned in the US. It suggested that "Certain individuals can at certain times and under certain circumstances be influenced to act abnormally without awareness of the influence". When challenged later to replicate the study, he failed to find significant results. Vicary provided no explanations for his results or any other details about his study to the public, claiming that it is part of a confidential patent. When Stuart Rogers interviewed the theater that supposedly conducted this experiment, the manager declared that there was no such test ever done (Rogers 1992)
In a television interview with Fred Danzig in 1962 for "Advertising Age", Vicary admitted that the original study was "a gimmick" and that the amount of data was "too small to be meaningful". He shied away from media attention after the disclosure. His papers are held by the Thomas J. Dodd Research Center at the University of Connecticut in Storrs. Numerous commentaries have appeared on this affair since 1957.
Popcorn experiment.
One of the most commonly known examples of subliminal messaging is Vicary’s movie theater "experiment" in 1957, purportedly in Fort Lee, NJ. In his press release, he claimed that 45,699 people were exposed to subliminal projections telling them to "Eat Popcorn" and "Drink Coca-Cola", causing a 57.5 percent sales increase for popcorn and an 18.1 percent increase in Coca-Cola sales. Vicary provided no explanations for his results making it impossible to reproduce his results. Taken in context with evidence that no experiment even took place, Vicary’s results can be considered completely fraudulent. Vicary later retracted his claims in a television interview, but Vicary’s original claims spread rapidly and lead to widespread acceptance of subliminal messaging, even today. (O’Barr 2005).
