Research conducted by the Annenberg Public Policy Center has found that the presence of tobacco-related content in 855 top-30 grossing box-office films, 15 movies per year from 1950-2006, has dramatically declined in parallel with actual cigarette consumption in the United States from the 1960s to 2006. In this study tobacco portrayal was defined as “The portrayal of anything tobacco-related, including smoking ads, logos, or paraphernalia, as well as implied or direct tobacco consumption” per five-minute segment.
