The effect of Nineteen Eighty-Four on the English language is extensive; the concepts of Big Brother, Room 101, the Thought Police, thoughtcrime, unperson, memory hole (oblivion), doublethink (simultaneously holding and believing contradictory beliefs) and Newspeak (ideological language) have become common phrases for denoting totalitarian authority. Doublespeak and groupthink are both deliberate elaborations of doublethink, and the adjective "Orwellian" means similar to Orwell's writings, especially Nineteen Eighty-Four. The practice of ending words with "-speak" (such as mediaspeak) is drawn from the novel.[118] Orwell is perpetually associated with 1984; in July 1984, an asteroid was discovered by Antonín Mrkos and named after Orwell.
References to the themes, concepts and plot of Nineteen Eighty-Four have appeared frequently in other works, especially in popular music and video entertainment. An example is the worldwide hit reality television show Big Brother, in which a group of people live together in a large house, isolated from the outside world but continuously watched by television cameras.
In November 2012, the United States government argued before the US Supreme Court that it could continue to utilize GPS tracking of individuals without first seeking a warrant. In response, Justice Stephen Breyer questioned what that means for a democratic society by referencing Nineteen Eighty-Four, stating "If you win this case, then there is nothing to prevent the police or the government from monitoring 24 hours a day the public movement of every citizen of the United States. So if you win, you suddenly produce what sounds like Nineteen Eighty-Four... "[119]
The book touches on the invasion of privacy and ubiquitous surveillance. From mid-2013 it was publicised that the NSA has been secretly monitoring and storing global internet traffic, including the bulk data collection of email and phone call data. Sales of Nineteen Eighty-Four increased by up to seven times within the first week of the 2013 mass surveillance leaks.[120][121][122] The book again topped the Amazon.com sales charts in 2017 after a controversy involving Kellyanne Conway using the phrase "alternative facts" to explain discrepancies with the media.[123][124][125][126]
Nineteen Eighty-Four was number three on the list of "Top Check Outs Of All Time" by the New York Public Library.[127]
Nineteen Eighty-Four entered the public domain on 1 January 2021, 70 years after Orwell's death, in most of the world. It is still under copyright in the US until 95 years after publication, or 2044.[128][129]
