John Banzhaf started the ball rolling on tobacco advertising. He noticed numerous advertisements on CBS (a broadcasting station) that promoted cigarette smoking. Banzhaf was also aware of the FCC's Fairness Doctrine that stated, "if you are going to broadcast a controversial topic, you must also broadcast the other side of the issue." Banzhaf wrote CBS demanding that the dangers of smoking have time to be advertised. CBS said no and he went to the FCC. The FCC found that Banzhaf was correct and decided to run one anti-smoking commercial for every three cigarette ads. The result was a decline in cigarette sales.This also resulted in Big Tobacco lobbying congress to ban all cigarette advertising. Television tobacco ads went off the air at the end of 1970, as did the free anti-smoking ads. Much of the cigarette advertising money shifted to print media.
