In particular, the media often try to make people believe something which is not true. Newspapers publish some ludicrous stories every year, although some of them are actually true. It’s entertaining to try to guess which stories are true and which are fake. In the April Fool’s stories, they often include a clue to the fact that it’s a joke. For example the name of an ‘expert’ quoted in the article might be an anagram of ‘April Fool’.
Radio and television programmes have also fooled many people by broadcasting reports which are untrue. One programme announced the invention of an amazing new weight-loss product - water which contained minus calories!
And one of the most famous hoaxes ever was broadcast by the BBC itself in 1957! A very serious news programme called Panorama reported on the poor spaghetti harvest in Switzerland, and showed pictures of farmers picking spaghetti from trees! Hundreds of people were taken in and wrote to the BBC asking how to grow their own spaghetti.
