INGSOC meaning in Academic & Science ?

Oceania, Eurasia and Eastasia are the three fictional superstates in George Orwell's 1949 dystopian novel Nineteen Eighty-Four. All that Oceania's citizens know about the world is whatever the Party wants them to know, so how the world evolved into the three states is unknown; and it is also unknown to the reader whether they actually exist in the novel's reality, or whether they are a storyline invented by the Party to advance social control. The nations, so far as can be inferred, appear to have emerged from nuclear warfare and civil dissolution over 20 years between 1945 and 1965.
