A Pop Promo
Queen also admitted that they would feel self-conscious lip-syncing to the operatic section of the song. So they decided to shoot a promotional video, or “pop promo” which was the industry term. It would be shown on UK music shows and on other shows around the world, such as American Bandstand.

Though some artists did video clips, it was only after the success of “Bohemian Rhapsody” that it became popular practice for record companies to produce pop promos for single releases. The video was later voted the 4th greatest music video of all time by the British public for The 100 Greatest Pop Videos in 2005.
