The Swedish Hockey League (officially SHL; ) is a professional ice hockey league, and the highest division in the Swedish ice hockey system. The league currently consists of 14 teams. The league was founded in 1975, and while Swedish ice hockey champions have been crowned through various formats since 1922, the title and the Le Mat Trophy have been awarded to the winner of the SHL playoffs since the league's inaugural 1975–76 season. In the 2010–11 season, the SHL was the world's most evenly matched professional ice hockey league. During the 2011–12 season, the SHL was the most well attended ice hockey league in Europe, averaging 6,385 spectators per game, however in 2013–14, the SHL was third best in Europe, with an attendance average of 5,978. The SHL was the second most popular sports team league within Sweden, after the football league Allsvenskan, which in the 2013 season had an average attendance of 7,627. The league was founded in 1975 as the Elitserien (in English the Swedish Elite League or SEL), and initially featured 10 teams, though this was expanded to 12 for the 1987–88 season. The league was renamed the SHL in 2013, and in 2014, a number of format changes were announced, including an expansion to 14 teams to be finalized prior to the 2015–16 season, and a new format for promotion from and relegation to HockeyAllsvenskan, the second tier league. Teams from the SHL participate in the IIHF's annual Champions Hockey League (CHL), competing for the European Trophy. Participation is based on the strength of the various leagues in Europe (excluding the European/Asian Kontinental Hockey League). Going into the 2022–23 CHL season, the SHL was ranked the No. 1 league in Europe, allowing them to send their top five teams to compete in the CHL. History The Swedish Ice Hockey Championship was awarded for the first time in 1922, only two years after ice hockey was introduced in Sweden by the American film director Raoul Le Mat. At this point, the Swedish Championships were held as a separate tournament. It was not until the 1952–53 season that the championship was awarded to the winner of the top-tier hockey league, which at the time was Division I. Expansion The inaugural Elitserien season began on 5 October 1975, with the league consisting of 10 teams, each playing one another four times—two at home and two on the road—for a
