I was 11 when the last ad aired but they must have been really effective because I can still remember so many of them!
Benson & Hedges "silly millimeter longer" "You can take Salem out of the country but..." "I'd rather fight than switch" "Marlboro Country" "You've come a long way baby"...
Fortunantly I always hated the smell of the things and never took up the habit.
From TVparty.com:
"The last cigarette commercial (for Virginia Slims) was broadcast on the Johnny Carson Tonight Show at 11:59pm on January 1, 1971. It was expected to be devastating for the networks when tobacco ads were banned - but they did all right without them, in spite of immediately losing $220 million dollars a year in revenues."
