The National Hockey League (NHL) was established in Montréal, Québec, on November 26, 1917. For the next 25 years, the newly formed league underwent numerous changes in league teams, scheduling and playoff format. By 1942, there were only six teams left in the NHL. Known as the “Original Six”, the Montreal Canadiens, Toronto Maple Leafs, Boston Bruins, Chicago BlackHawks, Detroit Red Wings and New York Rangers teams played until 1967, where 6 more expansion teams were added.
Today, there are 31 team franchises, 7 in Canada and 24 in the U.S. The teams compete for the Stanley Cup, the oldest professional sports trophy in North America.
