In the United States, the First Amendment to the Constitution prohibits the government from censoring publications. This means that the government cannot prevent or limit the publication of any material, regardless of its content. This protection extends to all forms of expression, including books, newspapers, magazines, films, and television shows.
The First Amendment also protects the right to distribute and receive these materials without government interference. This means that the government cannot prevent people from accessing information, even if that information is controversial or unpopular.
