1950 (first attested in Mary McCarthy), from Eng. author George
Orwell (pseudonym of Eric Blair, 1903-50), esp. in ref. to his novel
"1984." Ironically, it has come to be used in ref. to the totalitarian systems he satirized.
"It is as if George Orwell had conceived the nightmare instead of analyzed it, helped to create it instead of helping to dispel its euphemistic thrall." [Clive James]
