National Hockey League awards
The NHL's first championship trophy was the O'Brien Trophy, which was created by the National Hockey Association in 1910 and was acquired by the NHL in 1918, after which it was awarded to the playoff champion until 1923. The O'Brien Trophy was retired in favour of the Prince of Wales Trophy in 1924, which became the league's championship until the end of the Western Hockey League following the 1926 season, leaving the Stanley Cup exclusively in the hands of the National Hockey League.
