Today is the 104th birthday of the National Hockey League, which back in 1917 consisted of just five teams in Canada: the Ottawa Senators, Montreal Canadiens, Toronto Arenas (which grew into the Maple Leafs), Quebec Bulldogs (which became the Hamilton Tigers from 1920-1925) and the Montreal Wanderers (who won four NHA/NHL Stanley Cup championships but are now defunct).   The NHL grew out of the National Hockey Association (NHA) and other organizations that had existed as early as 1892, when the first champions took home the Stanley Cup.                     THE NHL today has 32 teams, seven in Canada (including those original teams from Montreal, Toronto and Ottawa) and 25 teams in the United States.  Players however, come from around the world, especially Canada, the US and Europe.  The league's 32nd and newest team, Seattle KRAKEN, began playing in the current 2021-2022 season.
