Sixteen clubs from ten cities have won the honor. With 26 titles Rosenborg is the most successful team, including 13 consecutive titles from 1992 through 2004. In the early years, Fredrikstad was highly successful, winning the first two titles and taking nine titles until 1960–61. Viking then took over dominance and rose to become the second-most winning team with their four consecutive titles from 1972 through 1975. The double—winning the league and cup the same season—has occurred fourteen times by six clubs.
