The complete House M.D. series broadcast 177 episodes.
Those episodes aired across eight seasons from November 2004 through May 2012. Most follow a medical-mystery structure in which Dr. Gregory House and his team develop and eliminate possible diagnoses while dealing with conflicts inside and outside the hospital.
The total includes the regular broadcast episodes of the series, including the concluding episode “Everybody Dies.” It is separate from the number of seasons: eight describes the program’s annual broadcast divisions, while 177 counts individual installments.
Episode totals can be confused because television databases sometimes list specials, international scheduling variations, or production entries differently. The standard series infobox count for House M.D. is 177 episodes. The program’s unusually long network seasons helped produce a much higher episode total than many later streaming dramas.
