Ideology refers to the underlying ideas and agenda promoted by media producers, whether consciously or not. In society, dominant ideologies reflect the beliefs of ruling groups. Hegemony describes how the dominant class imposes its worldview on society through institutions like media to gain consent without force. Popular culture can be used to divert attention from real issues and persuade intellectuals to accept the status quo, according to critic Noam Chomsky. The 1994 film Forrest Gump touches on several important social issues of the 1960s-70s era in the United States, including race relations, the peace movement, Vietnam War, women's roles, and disability representation.
