Orwell’s first reference to “Big Brother” is found
the third paragraph of the first chapter of 1984. He writes, " “The flat was seven flights up, and Winston, who was thirty nine and had a varicose ulcer above his right ankle, went slowly, resting several times on the way. On each landing, opposite the lift shaft, the poster with the enormous face
gazed from the wall. It was one of those pictures which are so contrived that the eyes follow you about when you move. BIG BROTHER IS WATCHING YOU, the caption read” 3. Thus, the concept of constant surveillance is presented at the very beginning the book.
