Alright it wasn't the first every attempt... but it was a starting point to help boost sales for the hit single a band releases.
from Wiki... "Though some artists, including Queen themselves (for example, "Killer Queen" and "Liar" already had "pop promos", as they were known at the time), had made video clips to accompany songs, it wasn't until after the success of "Bohemian Rhapsody" that it became regular practice for record companies to produce promo videos for artists' single releases."
there... this band is untouchable, they wrote classics!!! made HISTORY!!!!
alright... I'll let you get back to business, 2 more to go!!!!
