It tied in nicely with the recently published book, Hidden Persuaders, where Vance Packard described the ‘secret powers’ of advertisers to manipulate consumers. This led to a flurry of headlines and a lot of consulting income for Vicary. Vicary claimed that sales of popcorn and Coke went up 57.5% and 18.1% respectively. During a viewing of the film Picnic, he claimed to have flashed messages saying “Drink Coca-Cola” and “Hungry? Eat Popcorn” on the screen for 1/3000 of a second at a time, far below the threshold of conscious perception by the audience.

The 4A’s Marsha Appel looks at the rise and fall of the greatest advertising myth of the 20 th century. If you work in advertising, chances are that someone outside the industry has asked you about subliminal advertising.
