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". Other more serious and more critically acclaimed films about the hippie counterculture also appeared such as "Easy Rider" and "Alice's Restaurant". (See also: List of films related to the hippie subculture.) Documentaries and television programs have also been produced until today as well as fiction and nonfiction books. The popular Broadway musical "Hair" was presented in 1967.
