Dark Side of the Rainbow (also known as Dark Side of Oz or The Wizard of Floyd) refers to the pairing of the 1973 Pink Floyd music album The Dark Side of the Moon with the visual portion of the 1939 film The Wizard of Oz. This produces moments where the film and the album appear to correspond with each other. The title of the music video-like experience comes from a combination of the album title and the film's song "Over the Rainbow".
It is also a reference to the rainbow from a prism design on the cover of the Pink Floyd album. Band members and others involved in making of the album state that any relationship between the two works of art is merely a coincidence. In August 1995, a newspaper in Fort Wayne, Indiana, published the first mainstream media article about the "synchronicity", citing alt.music.pink-floyd.
Soon afterward, several fans began creating websites in which they touted the experience and tried to comprehensively catalog the corresponding moments. A second wave of awareness began in April 1997 when a Boston radio DJ discussed Dark Side of the Rainbow on the air, leading to further mainstream media articles and a segment on MTV news. In July 2000, the cable channel Turner Classic Movies aired a version of Oz with the Dark Side album as an alternate soundtrack.
Turner Entertainment has owned the rights to the film since 1986.
