The league was formed in 1979 to enable petanque players who lived in the Norwich area to continue to play throughout the winter, from November until the end of March.
By 1984 the league had expanded to 25 teams as the popularity of petanque in the County grew. By 1990, the league peaked at an amazing 47 teams. By 1996, numbers had fallen to 32 teams and to 24 teams by 2002. Numbers have remained steady at around 20 teams for each of the last fifteen years.
