The Root of All Evil? is a television documentary, written and presented by Richard Dawkins, in which he argues that the world would be better off without religion. The documentary was first broadcast in January 2006, in the form of two 45-minute episodes (The God Delusion and The Virus of Faith), on Channel 4 in the UK. Dawkins has said that the title The Root of All Evil? was not his preferred choice, but that Channel 4 had insisted on it to create controversy.
His sole concession from the producers on the title was the addition of the question mark. Dawkins has stated that the notion of anything being the root of all evil is ridiculous. Dawkins's book The God Delusion, released in September 2006, goes on to examine the topics raised in the documentary in greater detail. (Excerpt from en.wikipedia.org)
