National Hockey League

Gary Bettman has served as the NHL's commissioner since 1993, overseeing the league's expansion from 24 to 32 teams, the implementation of the salary cap, and the growth of hockey in non-traditional markets across the American South and West.

Bill Daly serves as the NHL's deputy commissioner, playing a key role in collective bargaining negotiations and day-to-day league operations.

John Ziegler served as the last NHL president before the commissioner title was adopted, overseeing the league during the Wayne Gretzky era and the growth of American expansion teams.

Clarence Campbell presided over the Original Six era and the first major expansion in 1967, when the league doubled from six to twelve teams. The Western Conference was named the Campbell Conference in his honor.
