NFL Films has chosen it as the greatest play of all time, as well as the most controversial.The play was a turning point for the Steelers, who reversed four decades of futility with their first playoff win ever, and went on to win four Super Bowls by the end of the decade. The play's name is a pun derived from the Immaculate Conception, a dogma in the Roman Catholic Church. The phrase was first used on air by Myron Cope, a Pittsburgh sportscaster who was reporting on the Steelers' victory. A Pittsburgh woman, Sharon Levosky, called Cope the night of the game and suggested the name, which was coined by her friend Michael Ord. Cope used the term on television and the phrase stuck.
