paragraph: The film examines the current and past relationships between the media , the U.S. government and corporations , analyzing the possible consequences of the concentration of media ownership . Making references to George Orwell 's novel Nineteen Eighty-Four , the film argues that reality has met and in some ways exceeded Orwell 's expectations about a society dominated by thought control , which is made possible by the media . According to the film , the mass media no longer report news , but manage it , deciding what makes the headlines and what is conveniently ignored , thus ultimately defining the framework upon which most other issues are discussed by the society . As an example , it is claimed that since the late 1980s there 's been an agenda pursued by the major media corporations regarding the deregulation of the media market , by which news reports sell all its benefits while neglecting its disastrous results . This documentary is a critical examination of the Fourth Estate , once the bastion of American democracy . Asking whether America has entered an Orwellian world of doublespeak where outright lies can pass for the truth , director Robert Kane Pappas explores what the media does n't like to talk about : itself . Meticulously tracing the process by which media has distorted and often dismissed actual news events , Pappas presents a riveting and eloquent mix of media professionals and leading intellectual voices on the media . From the very size of the media monopolies and how they got that way to who decides what gets broadcasted and what does n't , Orwell Rolls in His Grave moves through a troubling list of questions and news stories that go unanswered and unreported in the mainstream media .
