(the international edition stopped publishing in 1967, when The New York Times joined the owners of the New York Herald Tribune and The Washington Post to publish the International Herald Tribune in Paris). After only two years as publisher, Dryfoos died in 1963 and was succeeded by his brother-in-law, Arthur Ochs "Punch" Sulzberger, who led the Times until 1992 and continued the expansion of the paper. New York Times v. Sullivan (1964) The paper's involvement in a 1964 libel case helped bring one of the key United States Supreme Court decisions supporting freedom of the press, New York Times Co. v.

When The New York Times began publishing its series, President Richard Nixon became incensed. His words to National Security Advisor Henry Kissinger included "People have gotta be put to the torch for this sort of thing" and "Let's get the son-of-a-bitch in jail."
