Kalle Lasn talks about using TV commercials to disrupt the propaganda of corporations who are propagating dangerous memes. This famous TV commercial featuring Yul Brynner helped change the attitudes people had towards smoking cigarettes.
Accordng to Wikipedia:
Brynner died on October 10, 1985 (the same day as Orson Welles and my 15th birthday) in New York City at the age of 65. The cause of death was lung cancer brought on by smoking. Throughout his life, Brynner was always seen with a cigarette in his hand. In January 1985, nine months before his death, he gave an interview on Good Morning America, expressing his desire to make an anti-smoking commercial. A clip from that interview was made into just such a commercial by the American Cancer Society, and released after his death, which includes the warning “Now that I’m gone, I tell you, don’t smoke.”
