Svenska Basketligan, or the Swedish Basketball League (SBL), is the premier league for professional basketball in Sweden. The league was originally established in 1992 as Basketligan and was known as that prior to the season of 2006–07, but when the Swedish company Obol Investment signed an agreement with the Swedish Basketball Federation in early October 2006, the league was renamed Obol Basketball League (OBL). In January 2007 the name was changed to Ligan, meaning simply the League. History.
