A referee can also subtract points from a team's score if members break the improvisational theatre rules.
In December 1982 the final of the sixth season of the LNI was broadcast by Télé-Québec, which led to even greater popularity.
During the 1980s, the LNI traveled to face the best improv teams of France, which led to the formation of the Ligue d'improvisation française (French Improvisation League).
They also played matches in Belgium and Switzerland, which led to national improvisation leagues being formed in those countries.
In 1985, the first Improvisation World Cup brought together teams from Canada, France, Belgium, and Switzerland in Montreal, Quebec.
