Postmodernism refers to a distrust of theories and ideologies and a focus on conventions in media. Postmodernists believe that our lives are immersed in media and that the difference between reality and media representation is blurred. Postmodernism can be divided into "post," meaning after, and "modern," referring to keeping up with contemporary needs - suggesting postmodernism comes after the modern period's experimentation with representing reality through media. Another key postmodernist idea is that there are no completely new ideas left to produce in media like film, leading industries to rely on remakes, sequels and adaptations of past works.
