Freedom of the press in the United States is protected by the First Amendment to the United States Constitution. This amendment is generally understood to prevent the government from interfering with the distribution of information and opinions. Nevertheless, freedom of the press is subject to certain restrictions, such as defamation law.
In the Thirteen Colonies before the signing of the Declaration of Independence, the media was subject to a series of regulations. British authorities attempted to prohibit the publication and circulation of information of which they did not approve.
One of the earliest cases concerning freedom of the press occurred in 1734. In a libel case against The New York Weekly Journal publisher John Peter Zenger by British governor William Cosby, Zenger was acquitted and the publication continued until 1751. At that time, there were only two newspapers in New York City and the second was not critical of Cosby's government.
The First Amendment permits information, ideas and opinions without interference, constraint or prosecution by the government. It was adopted on December 15, 1791, as one of the ten amendments that constitute the Bill of Rights.
The 1931 U.S. Supreme Court decision Near v. Minnesota recognized freedom of the press by roundly rejecting prior restraints on publication, a principle that applied to free speech generally in subsequent jurisprudence. The court ruled that a Minnesota law targeting publishers of malicious or scandalous newspapers violated the First Amendment (as applied through the Fourteenth Amendment).
