Summary

Atheism refers to the conviction of the nonexistence of God. In the United States, atheism is diffuse, individualistic, and heavily reliant on the media for the cultivation of a sense of community. Intellectually and socially, American Atheism has its roots in a number of prior movements, including in particular the Deism of Thomas Paine and other American Revolutionaries and the broad free-thought movement of the 19th and early 20th centuries. These disparate strands of religious criticism coalesced into an atheist political movement predominantly during the course of the 20th century, through the deliberate efforts of individuals like Charles Lee Smith and Madalyn Murray O’Hair to capitalize on the exposure afforded by new media formats. Following the popularity of the Intelligent Design movement toward the end of the 1990s and the September 11th attacks, New Atheism emerged in the mid-2000s as a form of atheism reliant on new media, especially critical of fundamentalist interpretations of Christianity and Islam, and particularly devoted to scientific empiricism and rationality. In the early 21st century, atheism in the United States continues to be organized largely through the media, with official organizations operating primarily through annual conventions and local chapters. Atheism has constituted and continues to constitute an important form of identification for many Americans dissatisfied with a dominant religious culture.
