The Atheist Bus Campaign aims to place "peaceful and upbeat" messages about atheism on transport media in the UK, in response to evangelical Christian advertising. It was created by comedy writer Ariane Sherine and launched on 21 October 2008, with official support from the British Humanist Association and Richard Dawkins. The campaign's original goal was to raise £5,500 to run 30 buses across London for four weeks early in 2009 with the slogan: "There’s probably no God. Now stop worrying and enjoy your life."
