The answer to this question can be found in Chapter Four of Part One. The Ministry of Truth, where Winston works, is responsible for producing literature for the consumption of both Party members and proles. Orwell writes that the Ministry produces "newspapers, films, textbooks, telescreen programmes, plays, [and] novels" for the Party members that are full of rewritten history and Party propaganda. These included all sorts of literature, including children's books and Newspeak dictionaries, but they were all written to promote ideological conformity. The literature that the Ministry of Truth produced for the proles was of "a lower level," and consisted of "rubbishy newspapers containing almost nothing except sport, crime and astrology, sensational five-cent novelettes [and] films oozing with sex." The sentimental nonsense songs sung by the proles throughout the book were composed by a special machine called a "versificator." There is even a special section of the Ministry of Truth called Pornosec that produces pornography for the proles to consume. Party members were strictly prohibited from viewing this material, which was sent out in sealed envelopes to the neighborhoods where the proles lived. The Party is using two different methods to achieve the same end: power. The proles are kept docile through the proliferation of brainless literature and low art, and the Party members, through their consumption of media, are constantly exposed to propaganda.
