House M.D. broadcast for eight seasons between 2004 and 2012.
Fox premiered the medical drama in November 2004, and the series concluded with its eighth season in May 2012. Across that run, it followed Gregory House and successive teams of doctors as they investigated unusual illnesses at Princeton-Plainsboro Teaching Hospital.
The cast and story structure changed over time. House’s original diagnostic team gradually gave way to new doctors, while major arcs explored his relationships, addiction, professional conflicts, and changing approach to medicine.
The number is sometimes misremembered as seven because the series had seven full years before its final season, or because viewers count major team eras rather than broadcast seasons. The official television run consists of eight numbered seasons and 177 episodes.
