Tobacco company funded anti-smoking adverts
Am J Public Health 2006; 96: 2,154-2,160
Between 1998 and 2003 there was a run of adverts paid for by the tobacco industry that were aimed at teenagers and were designed to put them off smoking.
Unfortunately, research has shown that rather that putting kids off smoking after exposure to the adverts, children had lower perceived dangers of smoking and greater approval ratings.
As the marketers say, there's no such thing as bad publicity
