Cigarette ads are the textbook illustration of the power of advertising...in blind tests people couldn't identify their own brand, but were so attached to whatever image was shown in the spots--they'd rather fight than switch, as one of them said.
TV in the 1950s and 1960s: Smoke, drink beer, and eat sugar TV in the 1970s and 1980s: Don't smoke, but drink beer and eat sugar TV in the 1990s and beyond: Take these unpronounceable pills to undo the effects of a lifetime of smoking, eating sugar, and drinking beer
Re the Flintstones ads: Rather ironic that all four of the main voice actors on the show (Alan Reed, Jean Vander Pyl, Mel Blanc & Bea Benaderet) died of smoking related ailments.
