A group of six franchises comprised the National Hockey League for a quarter-century, starting in the 1942-43 season. These established hockey clubs shaped the landscape of professional ice hockey in North America for decades. The composition of this group remained unchanged until expansion occurred in 1967.
This era represents a significant period of stability and focused competition within the league. The enduring rivalries forged during this time contributed significantly to the sport’s growing popularity and established traditions that continue to resonate with fans. The financial security and concentrated talent pool also allowed these organizations to build strong, recognizable brands and develop iconic players.
