The New York Times and The Washington Post are frequently referred to as the "newspapers of record" in the United States. Although both newspapers have editorial pages, only The New York Times is considered a true news medium by most observers. The New York Times was first published on October 18, 1851, by the New York Times Company. It continues to be published today under the same company ownership except for a brief period in 1961 when it was purchased by the Washington Post Company. The paper has a national reputation for quality journalism and has been called the "paper of record" for American history. The Washington Post was founded on February 21, 1877, by George Graham Brett and Henry J. Raymond. It is also printed and published by The Washington Post Company. The paper has had many influential journalists over its history, including H. L. Mencken, Walter Lippmann, and William Safire. It is widely regarded as one of the premier newspapers in the country. Both papers are published six times a week and can be found in local grocery stores, gas stations, bookstores, and convenience stores across the United States.
