@luckytran I can’t find it, but I think that Feynman (if it wasn’t Sagan himself) said something about the advertising in the Boy Scouts’ magazine and how utterly preposterous it was and that it showed no respect for the audience. I’ve gotten a lot of mileage out of that.
Look at the things Fox News allows for ads: scams up and down the lineup, valueless commemorative coins, buy gold and silver.
