Ice hockey or simply known as hockey in North America, is a team sport played on ice skates, usually on an ice skating rink with lines and markings specific to the sport. It belongs to a family of sports called hockey. The two opposing teams score by using their ice hockey sticks to control and advance a vulcanized rubber hockey puck, and then shooting it into the net of the other team, each goal is worth one point. The team with the highest score after an hour of gameplay is declared the winner; ties are broken in overtime or a shootout. In a formal game, each team has six skaters on the ice at a time, barring any penalties, including a goaltender. It is a full contact game and one of the more physically demanding team sports.
The modern sport of ice hockey was developed in Canada, most notably in Montreal, where the first indoor game was played on March 3, 1875. It draws influence from shinty which originated in Scotland, as well as field hockey which originated in England. Some characteristics of ice hockey, such as the length of the ice rink and the use of a puck, have been retained to this day. Amateur ice hockey leagues began in the 1880s, and professional ice hockey originated around 1900. The Stanley Cup, emblematic of ice hockey club supremacy, was initially commissioned in 1892 as the "Dominion Hockey Challenge Cup" and was first awarded in 1893 to recognise the Canadian amateur champion and later became the championship trophy of the National Hockey League (NHL). In the early 1900s, the Canadian rules were adopted by the Ligue Internationale de Hockey sur Glace, in Paris, France, the precursor to the International Ice Hockey Federation (IIHF). The sport was played for the first time at the Olympics during the 1920 Summer Games—today it is a mainstay at the Winter Olympics. In 1994, ice hockey was officially recognized as Canada's national winter sport.
