You reminded me of a true story shared by an old advertising copywriter, Jerry della Femina. His company had landed the National Panasonic account .Back then being a Japanese firm was a drawback credibility wise. Japanese goods were regarded as cheap copies of things made in the West - and then there was the War. So in a brainstorming session with the top executives della Femina said ' hey I got a slogan, the whole campaign can be built on this slogan' What is it Jerry ? - ' From those wonderful people who brought you Pearl Harbour!' Silence. Of course nobody said it was a great slogan , for obvious reasons. But neither did anyway say it was in awful taste. And worst of all , he thought , nobody laughed. Later he realised they were all frozen with fear : what if the boss liked it ? Such is the wacky world of PR.
I heard a tale that after the Jonestown tragedy, a marketing executive noted that the poison used was made by his firm, and telexed the director to suggest they use the pictures in adverts (possibly in a black humour vein). The reply was that it made good sense but was unlikely to lead to repeat business.
