Some information, origins of subliminal advertisement

In 1957, market researcher James Vicary claimed that quickly flashing messages on a movie screen, in Fort Lee, New Jersey, had influenced people to purchase more food and drinks. Vicary coined the term subliminal advertising and formed the Subliminal Projection Company based on a six-week test. Vicary claimed that during the presentation of the movie Picnic he used a tachistoscope to project the words "Drink Coca-Cola" and "Hungry? Eat popcorn" for 1/3000 of a second at five-second intervals. Vicary asserted that during the test, sales of popcorn and Coke in that New Jersey theater increased 57.8 percent and 18.1 percent respectively.

However, in 1962 Vicary admitted to lying about the experiment and falsifying the results, the story itself being a marketing ploy. An identical experiment conducted by Dr. Henry Link showed no increase in cola or popcorn sales. A trip to Fort Lee, where the first experiment was alleged to have taken place, would have shown straight away that the small cinema there couldn't possibly have had 45,699 visitors through its doors in the space of 6 weeks. This has led people to believe that Vicary actually did not conduct his experiment at all.

However, before Vicary's confession, his claims were promoted in Vance Packard's book The Hidden Persuaders, and led to a public outcry, and to many conspiracy theories of governments and cults using the technique to their advantage. The practice of subliminal advertising was subsequently banned in the United Kingdom and Australia, and by American networks and the National Association of Broadcasters in 1958.

But in 1958, Vicary conducted a television test in which he flashed the message "telephone now" hundreds of times during a Canadian Broadcasting Corporation program, and found no noticeable increase in telephone calls.

In 1973, commercials in the United States and Canada for the game Hūsker Dū? flashed the message "Get it". During the same year, Wilson Bryan Key's book Subliminal Seduction claimed that subliminal techniques were widely used in advertising. Public concern was sufficient to cause the FCC to hold hearings in 1974. The hearings resulted in an FCC policy statement stating that subliminal advertising was "contrary to the public interest" and "intended to be deceptive". Subliminal advertising was also banned in Canada following the broadcasting of Hūsker Dū? ads there.
