The
island dwelling-place of
Winston Smith in
George Orwell's novel
Nineteen eighty-four. Formerly called
Great Britain, it was renamed according to the principles of
Ingsoc after it was absorbed into the entity known as
Oceania.
Since Orwell wrote his novel in
1949 after the immense American military buildup for
World War II, and a continued presence because of the emerging
Cold War, and the UK's membership in
NATO, one can easily see where the name came from.
