The story
From the start of Swedish league speedway in 1948 until 1981 the highest speedway league in Sweden was called Division 1. In 1982 Elitserien was formed, consisting of only six teams where the top four teams qualified for the playoffs. Getingarna became the first winners after defeating Njudungarna in the finals. The league size was increased to seven teams in 1983 and to eight teams in 1984, a league size that was maintained until the 1996 season when the league expanded to nine teams and then to ten teams the following season. In 1986 the playoffs lost its championship status; instead the winner of the league became the Swedish champions. However, in 2000, playoffs were reintroduced as a championship final.
