Thomas Carlyle wrote in 1840 that Edmund Burke had called the reporters' gallery in Parliament a Fourth Estate more important than the three estates of the realm, and the phrase came to describe the press as an independent check on power. In America, the 1735 acquittal of printer John Peter Zenger on charges of seditious libel against New York's colonial governor became a symbol of press freedom, and the First Amendment provides that Congress shall make no law abridging the freedom of speech, or of the press.
The Supreme Court has given the press strong protection. Near v. Minnesota in 1931 barred most prior restraints on publication, New York Times Co. v. Sullivan in 1964 required public officials suing for libel to prove actual malice, and New York Times Co. v. United States in 1971 allowed publication of the Pentagon Papers. Reporting on Watergate in the 1970s became a model of investigative journalism, and the Freedom of Information Act, the White House press pool, and congressional press galleries give reporters regular access to government.
The news business has changed sharply, as thousands of local newspapers have closed since 2005 and audiences have moved online. Trust in the media has fallen, with Gallup surveys showing record lows in the 2020s and deep partisan differences. In 2025 the White House restricted access for the Associated Press over its style choices, the Pentagon adopted new credential rules many outlets declined to accept, and Congress rescinded funding for the Corporation for Public Broadcasting. Supporters of these steps cited bias and accountability, while press groups called them threats to independent reporting.
