How many seasons of "Doc Martin" did ITV initially commission?

Between 2004 and 2013, ITV has aired six seasons, totaling 46 episodes of the medical comedy-drama "Doc Martin" in the United Kingdom. Series seven began airing in September 2015.

"Doc Martin" was inspired by a character in the 2000 comedy film "Saving Grace." It was co-created by Dominic Minghella and Martin Clunes, the latter of whom stars in the title role. The series recounts the trials and misadventures of a socially challenged doctor, who has taken up general practice in a seaside village after sudden development of a phobia of blood makes it impossible for him to continue practice as a London surgeon.
