literature, and not just in the US, but around the world. Eugene McCarthy's brief presidential campaign successfully persuaded a significant minority of young adults to "get clean for Gene" by shaving their beards or wearing longer skirts; however the "Clean Genes" had little impact on the popular image in the media spotlight, of the hirsute hippy adorned in beads, feathers, flowers and bells. A sign of this was the visibility that the hippie subculture gained in various mainstream and underground media. Hippie exploitation films are 1960s exploitation films about the hippie counterculture with stereotypical situations associated with the movement such as cannabis and LSD use, sex and wild psychedelic parties. Examples include The Love-ins, Psych-Out, The Trip, and Wild in the Streets.

Their stated intention to protest the 1968 Democratic National Convention in Chicago in August, including nominating their own candidate, "Lyndon Pigasus Pig" (an actual pig), was also widely publicized in the media at this time. In Cambridge, Massachusetts hippies congregated each Sunday for a large "be-in" at Cambridge Common with swarms of drummers and those beginning the Women's Movement. In the US the Hippie movement started to be seen as part of the "New Left" which was associated with anti-war college campus protest movements. The New Left was a term used mainly in the United Kingdom and United States in reference to activists, educators, agitators and others in the 1960s and 1970s who sought to implement
