While the official corporate philosophy of Google does not contain the words "Don't be evil", they were included in the prospectus (on Form S-1) of Google's 2004 IPO (a letter from Google's founders, later called the "'Don't Be Evil' manifesto"): "Don't be evil. We believe strongly that in the long term, we will be better served—as shareholders and in all other ways—by a company that does good things for the world even if we forgo some short term gains." The motto is sometimes incorrectly stated as "Do no evil".
