Standing as one type of movie within the broader comedy genre, the parody movie has an unusual history. Parody movies have existed for almost as long as cinema has, with the genre dating back as far as 1905, though it's also safe to say that it took considerably more time for this type of film to truly take off. The 1970s and 80s likely represent the golden age for what's now identifiable as a parody movie, with this brand of comedy being all over the place quality-wise in the decades since said golden age.
