The adjective ‘Orwellian’ has entered the language. The Oxford English Dictionary defines the term as describing a repressive state. Orwell’s work has also entered the visual lexicon. Amazingly this poster “Secure Beneath Watchful Eyes’ is real and was used in 2002 to advertise CCTV used by Transport For London. It was designed by the Central Illustration Agency, who were paid £2,000 for the work. The style is very post-war (i.e. the time 1984 was being written) and to many eyes quite sinister.
However London Transport seemed quite happy to use it and didn’t see any parody in it. The London Transport Museum blog did.
