Grey's Anatomy debuted as a mid-season replacement for Boston Legal in 2005, and became a bona fide success after just nine episodes. The combination of medical drama, likable but flawed characters coming of age, and one hot doc known as McDreamy catapulted the show to smash hit status the following season.
Critically, Seasons Three and Four failed to live up to the lofty standards of the first two but the series remains one of the top ten highest rated on TV.
Grey's Anatomy is created by Shonda Rhimes. Its diverse and talented cast stars Ellen Pompeo, Patrick Dempsey, Sandra Oh, Chandra Wilson, Katherine Heigl, T.R. Knight, Justin Chambers, James Pickens, Jr., Brooke Smith, Eric Dane, Sara Ramirez and Chyler Leigh.
Former stars include Isaiah Washington (fired) and Kate Walsh (left for spin-off Private Practice).
