The expression goes back at least to the 1930s, being used publicly in that decade by two former members of Notre Dame's Four Horsemen, Elmer Layden and Jim Crowley. Originally meaning any sort of desperation play, a 'Hail Mary' gradually came to denote a long, low-probability pass, typically of the 'alley-oop' variety, attempted at the end of a half when a team is too far from the end zone to execute a more conventional play, implying that it would take divine intervention for the play to succeed. For more than forty years, use of the term was largely confined to Notre Dame and other Catholic universities.
