The 2004âÂÂ05 Serie B is the 73rd season since its establishment in 1929. It is the second highest football league in Italy.
Arezzo, Catanzaro, Cesena and Crotone had been promoted from Serie C, while Perugia, Modena, and Empoli had been relegated from Serie A, and Ancona had lost their national professional licence.
Following the long-standing consequences of the "Caso Catania", the league included 22 teams, while promotions decreased to three spots.
Promotion playoffs were also introduced.

(later became a relegation play-off)
Torino Calcio promoted to Serie A, but later it went bankrupt and it was restored in 2005âÂÂ06 Serie B by the Lodo Petrucci. Perugia Calcio also went bankrupt and it was restored in 2005âÂÂ06 Serie C1 by the Lodo Petrucci.
This promotion play-off consequently became a relegation play-off.
(later annulled)
Vicenza Calcio was lucky because its relegation was annulled following the Caso Genoa.
