Why Horrible Histories succeeds
Part of the reason why TV series Horrible Histories is so successful is that it "never patronises children", says Terry Deary, the British author whose books the show is based on.
He says: "The show doesn't treat children as little ignorant human beings. There is a lot of children's television where presenters shout at the children, as if they need to be shouted at.
"But Horrible Histories is very quiet, beautifully produced and based on facts. It is also written by adult writers, not children's writers, so the children are never patronised. And the children love this."
Deary, 66, is the bestselling writer of the Horrible Histories book series, which has over 60 titles to date and has sold over 25 million copies in 30 languages.
