Year: 1915

It's kind of unfathomable now to think of football without the forward pass, but until 1906 it was straight up banned in professional football. When they powers that be decided too many people were dying on the field, though, they had the sense to make it legal. It didn't really come into fashion until 1913, when upstart Notre Dame assistant coach Knute Rockne decided to make it a central part of his offensive gameplan. He developed plays over the summer with fellow coach Gus Dorais while the pair was working as lifeguards at a lake in Ohio (seriously), and when the Irish had success using it to beat a much bigger Army squad that season it became a part of the college game forever more.
