Memory hole

A memory hole is any mechanism for the deliberate alteration or disappearance of inconvenient or embarrassing documents, photographs, transcripts or other records, such as from a website or other archive, particularly as part of an attempt to give the impression that something never happened.^[1][2] The concept was first popularized by George Orwell's 1948 dystopian novel Nineteen Eighty-Four, where the Party's Ministry of Truth systematically re-created all potentially embarrassing historical documents, in effect, re-writing all of history to match the often-changing state propaganda. These changes were complete and undetectable.
