John Peter Zenger (October 26, 1697 July 28, 1746) was a German printer and journalist in New York City. Zenger printed The New York Weekly Journal. He was accused of libel in 1734 by William Cosby, the royal governor of New York, but the jury acquitted Zenger, who became a symbol for freedom of the press.In 1733, Zenger began printing The New York Weekly Journal, which voiced opinions critical of the colonial governor, William Cosby. On November 17, 1734, on Cosby's orders, the sheriff arrested Zenger. After a grand jury refused to indict him, the Attorney General Richard Bradley charged him with libel in August 1735. Zenger's lawyers, Andrew Hamilton and William Smith, Sr., successfully argued that truth is a defense against charges of libel.



Freedom of the press or freedom of the media is the fundamental principle that communication and expression through various media, including printed and electronic media, especially published materials, should be considered a right to be exercised freely. Such freedom implies the absence of interference from an overreaching state; its preservation may be sought through constitution or other legal protection and security.

Without respect to governmental information, any government may distinguish which materials are public or protected from disclosure to the public. State materials are protected due to either one of two reasons: the classification of information as sensitive, classified or secret, or the relevance of the information to protecting the national interest. Many governments are also subject to "sunshine laws" or freedom of information legislation that are used to define the ambit of national interest and enable citizens to request access to government-held information.

The United Nations' 1948 Universal Declaration of Human Rights states: "Everyone has the right to freedom of opinion and expression; this right includes freedom to hold opinions without interference, and to seek, receive, and impart information and ideas through any media regardless of frontiers".This philosophy is usually accompanied by legislation ensuring various degrees of the freedom of the scientific research (known as the scientific freedom), the publishing, and the press. The depth to which these laws are entrenched in a country's legal system can go as far down as its constitution. The concept of freedom of speech is often covered by the same laws as freedom of the press, thereby giving equal treatment to spoken and published expression. Freedom of the press was formally established in Great Britain with the lapse of the Licensing Act in 1695. Sweden was the first country in the world to adopt freedom of the press into its constitution with the Freedom of the Press Act of 1766.
