If you read about Mary Lasker you will understand a lot about health propaganda, advertising and medical research funding in the United States.
Here is a quote from the Wikipedia post on Mrs. Lasker (accessed today 4/8/2021)
"Together, they were the first to apply the power of modern advertising and promotion to fighting cancer. They joined the American Society for the Control of Cancer which at the time was sleepy and ineffectual and transformed it into the American Cancer Society. The Laskers ousted the board of directors. Afterwards, they raised then record amounts of money and directed much of it to research. The American Cancer Society also fought lung cancer through prevention via anti-smoking campaigns. Using TV equal-time provisions, they were able to counter cigarette advertising with their own message.[13]
In 1970, Congress passed a law banning the advertising of cigarettes on television, so the anti-smoking commercials likewise went off the air. [14] "
