Modern music videos are primarily made and used as a marketing device intended to promote the sale of music recordings. Although the origins of music videos date back much further, they came into prominence in the 1980s, when MTV based their format around the medium. Prior to the 80s, these works were described by various terms including "illustrated song", "filmed insert", "promotional (promo) fi
lm", "promotional clip" or "film clip". Music videos use a wide range of styles of film making techniques, including animation, live action filming, documentaries, and non-narrative approaches such as abstract film. Some music videos blend different styles, such as animation and live action. Many music videos do not interpret images from the song's lyrics, making it less literal than expected.
