In 1988 and 1989, the award criteria were changed and the video accolades were presented under the categories Best Concept Music Video and Best Performance Music Video. The awards were returned to the original format in 1990. Except in 1988 and 1989, the Grammy Award for Best Long Form Music Video recipients included the artists, directors, and producers associated with the winning videos. The Best Music Film category is one of two categories in the Best Music Video/Film Field. The other one is Best Music Video, which recognises stand-alone videos of one song or performance.
