An anti-pornography movement has existed in the United States since before the 1969 Supreme Court decision of "Stanley v. Georgia", which held that people could view whatever they wished in the privacy of their own homes, by establishing an implied "right to privacy" in U.S. law. This led President Lyndon B. Johnson, with the backing of Congress, to appoint a commission to study pornography. The anti-pornography movement seeks to maintain or restore restrictions and to increase or create restrictions on the production, sale or dissemination of pornography.
