Origins In the 1980s, as Finnish society changed, the role of
pesäpallo had to be re-examined. The sport had long drawn its strength from the countryside and village game culture, but with urbanisation, the rural population was dwindling and pesäpallo needed a new direction. In the 1980s, the Finnish Pesäpallo Association launched the "Pesäpallo is the most Finnish Game" (, POPS) project, which aimed to communicate the new future of pesäpallo to clubs, local politicians and the media. The project gave pesäpallo a social profile and practical marketing and visibility measures, as well as efforts to turn pesäpallo into a television product. Superpesis Oy was set up as the marketing organisation for the men's and women's main league clubs. At the same time, work began on improving conditions, including the development of match venues, the introduction of sand artificial turf fields and the construction of pesäpallo stadiums.
The boom in pesäpallo (1990s) The first Superpesis season was played in 1990. With the new Superpesis, pesäpallo also gained a new dominant team when
Sotkamon Jymy won the Finnish championship for the first time since 1963. Sotkamon Jymy was regularly ranked in the top three or higher for eight years and won six championships during the decade. Kitee made a return to the gold medal in 2005, but Jymy returned as champions again in 2006 and 2009. Throughout the decade, Sotkamo Jymy played at least in the top three. During the decade,
Pattijoen Urheilijat became champions for the first time in their history in 2008 and the club won several medals during the decade. After a long bronze medal season, Joensuun Maila became the leading pesäpallo club and won the Finnish championship in 2018 and 2019, while Kouvolan Pallonlyöjät established itself as the fourth largest club. ==Clubs==
