Karl Marx was a 19th century philosopher who developed the theory of Marxism. Marxist instrumental theory holds that mass media owners control media content to transmit a conservative ideology and maintain the status quo of capitalism. The media performs ideological functions like portraying the wealthy positively and spreading the myth of meritocracy. It also dismisses radical views and divides audiences. The audience is seen as passive and easily manipulated. There is historical evidence that media owners manipulated content, though critics argue audiences are active and media aims to make a profit, not spread narrow views.
