Wikipedia
Prolefeed is a Newspeak term in the novel Nineteen Eighty-Four by George Orwell. It was used to describe the deliberately superficial literature, movies and music that were produced by Prolesec, a section of the Ministry of Truth, to keep the " proles" (i.e., proletariat) content and to prevent them from becoming too knowledgeable. The ruling Party believes that too much knowledge could motivate the proles to rebel against them. In the novel, Prolesec is described in detail:
The term is used occasionally to describe shallow entertainment in the real world. For example, Charles Spencer, reviewing the Queen musical We Will Rock You for the Daily Telegraph, described it as 'prolefeed at its worst'. Theodore Dalrymple wrote in the The Spectator that "France .... is less dominated by mass distraction (known here as popular culture, but in Nineteen Eighty-Four as prolefeed) than Britain is."
The term has also been applied to fast food, such as that of McDonald's: "Once seen as the all-American corporation, 'McDonald’s' is now shorthand for a globalist mass culture that provides cheap, unhealthy food to lower-class people. McDonald’s is, quite literally, prolefeed. Part of this image was a deliberate choice by the corporation."
Usage examples of "prolefeed".
An example was prolefeed, meaning the rubbishy entertainment and spurious news which the Party handed out to the masses.
Almost invariably these words -- goodthink, Minipax, prolefeed, sexcrime, joycamp, Ingsoc, bellyfeel, thinkpol, and countless others -- were words of two or three syllables, with the stress distributed equally between the first syllable and the last.
