Serie B (Italian pronunciation: [ˈsɛːrje ˈbi][1]), currently named Serie BKT for sponsorship reasons,[2] is the second-highest division in the Italian football league system after the Serie A. It has been operating for over ninety years since the 1929–30 season. It had been organized by Lega Calcio until 2010, when the Lega Serie B was created for the 2010–11 season. Common nicknames for the league are campionato cadetto and cadetteria, since cadetto is the Italian name for junior or cadet.
