Serie B , currently named Serie B ConTe.it due to sponsorship reasons, is the second-highest division in the Italian football league system after the Serie A. It is contested by 22 teams and organized by the Lega Serie B since July 2010, after the split of Lega Calcio that previously took care of both the Serie A and Serie B. Common nicknames for the league are campionato cadetto and cadetteria, as cadetto is the Italian for junior or cadet.

The Campeonato Brasileiro Série B, commonly referred to as the Brasileirão Série B or simply Série B is the second tier of the Brazilian football league system. The competition format has changed almost every year since it first occurred, in 1971. In some years, it was not played at all. However, since 2006, it has been contested by 20 teams in a double round-robin format with the top four teams being promoted to Campeonato Brasileiro Série A and the bottom four teams being relegated to Campeonato Brasileiro Série C.
