How many seasons did House M.D. run from 2004 to 2012?

House M.D. ran for eight seasons from 2004 to 2012.

Fox broadcast the series for eight television seasons, following Gregory House and the changing teams around him at Princeton-Plainsboro Teaching Hospital. The early seasons focused heavily on House's original diagnostic fellows, while later seasons introduced new colleagues and shifted the professional and personal relationships within the hospital.

The show premiered in November 2004 and concluded in May 2012. Its final season dealt with House's legal and personal consequences after the events of the seventh season, alongside new medical cases and developments involving James Wilson and other principal characters.

Season count can sometimes be confused with episode count. House had eight seasons but 177 episodes, because most seasons contained roughly 20 to 24 installments. The series also produced several special episodes and a two-part finale, but those do not create an additional ninth season.
