From 1937 to 1968, the same rules now used for winning the Presidents' Trophy were used to award the Prince of Wales Trophy. With the Modern Era expansion in the 1967–68 season and the start of the West Division, the Wales Trophy was awarded to the team that finished in first place in the East Division during the regular season. However, no trophy was awarded to the team that finished with the best overall record in the league during this period, and no trophy at all was awarded from the 1981–82 season through the 1984–85 season; the Wales and Campbell trophies were transferred to the playoff champions of those conferences in 1981–82. A cash bonus was given to each player on the team with the league's best regular-season record during these years, to which the Presidents' Trophy was added in 1985–86.
