The Spengler Cup is an annual invitational ice hockey tournament held in Davos, Switzerland. First held in 1923, the Spengler Cup is often cited as the oldest invitational ice hockey tournament in the world. The event is hosted by the Swiss team HC Davos and is played each year in Davos from 26 December to 31 inclusively. Currently, all games are held at the Eisstadion Davos.
It was originally devised by Dr. Carl Spengler as a means to promote teams from German-speaking Europe, who might have suffered ostracism in the aftermath of World War I. Eventually, the tournament grew well beyond expectations. Many of Europe’s most prestigious clubs and national programs have appeared, including Soviet, Czechoslovak, Swedish, German, and Finnish powerhouses. Throughout its history, club or national teams from 13 countries have won the tournament, with Team Canada winning the most cups as a club (16) while various teams from Switzerland have won the most cups for one country (20).
The Spengler Cup is the second-largest sporting event in Switzerland, after tennis’ Swiss Indoors in Basel. Since 1985, UBS has been the main sponsor and presenting partner of the Spengler Cup. Other current major sponsors are Würth, Schenker Storen, Škoda, Calanda, and McDonald’s – each of whom, along with UBS, is the main tournament sponsor of one of the six teams each year.
The Spengler Cup is broadcast on Schweizer Radio und Fernsehen in Switzerland, on Eurosport 2 in most of Europe, on Match TV and NTv2 in Russia, on Sport1 in Czechia, Slovakia, and Hungary, on Šport TV in Slovenia, on TSN and RDS in Canada and on the free-to-air channel FreeSports in the United Kingdom.
