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. Orwell is perpetually associated with 1984; in July 1984, an asteroid was discovered by Antonín Mrkos and named after Orwell.

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. 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.
The book also shows mass media as a catalyst for the intensification of destructive emotions and violence. Since the 20th century, news and other forms of media have been publicising violence more often.

The play opened on Broadway in 2017.
