An atheist group is running ads on two dozen New York City buses to raise "atheist pride'' among nonbelievers.
The 12-foot-long ads have a blue background and three-foot-high white letters that proclaim "You don't have to believe in god to be a moral or ethical person."
Members of the New York City Atheists will hold a Saturday press conference to discuss the ads at Manhattan's Columbus Circle.
Spokeswoman Jane Everhart says American society is increasingly accepting of atheists and says President Obama even mentioned "nonbelievers'' in his inaugural speech.
The ad campaign wants to reassure secretive nonbelievers that "it's OK to be an atheist''
The 30-day campaign was funded by an anonymous atheist.
