Atheist billboard
An atheist billboard is an outdoor billboard that promotes divestment or outreach to atheists, nontheists, or nonreligious individuals. Similar to the Atheist Bus Campaign first undertaken in the United Kingdom by Ariane Sherine in October 2008, atheist billboards often include messages or graphics which either assert the lack of evidence for the existence of deities or positively encourage those who are privately questioning the existence of a deity (or the supernatural), and such advertisements have garnered controversy and negative reactions from local theists.
