I saw this on the BBC website
Can not find the advert the article referencesIn the 21st Century, the term "flat-earther" is used to describe someone who is spectacularly - and seemingly wilfully - ignorant. But there is a group of people who claim they believe the planet really is flat. Are they really out there or is it all an elaborate prank?
Nasa is celebrating its 50th birthday with much fanfare and pictures of past glories. But in half a century of extraordinary images of space, one stands out.
On 24 December 1968, the crew of the Apollo 8 mission took a photo now known as Earthrise. To many, this beautiful blue sphere viewed from the moon's orbit is a perfect visual summary of why it is right to strive to go into space.
Not to everybody though. There are people who say they think this image is fake - part of a worldwide conspiracy by space agencies, governments and scientists.
Welcome to the world of the flat-earther.
I do remember one, many years ago which was an advert for a cigar, where the captain of the sailing vessel refuses to turn back because he does not follow his sailors belief that the world is flat, and is convinced it is round. Suddenly the lookout shouts that they are at the edge of the world, and it is flat. So the captain lights the cigar and we follow him as the ship is swept by the currents off of the edge of the world.
Later there was an advert for a chocolate bar where they played on the myth that the ancients thought the world was flat.
