Created by series producer Shonda Rhimes, the character was introduced in season two as Dr. Derek Shepherd's best friend who acted as the catalyst for the end of Shepherd's marriage when Shepherd caught Sloan sleeping with his wife, Dr. Addison Montgomery. Soon after moving to Seattle Grace Hospital as an attending specializing in plastic surgery to reconcile with Derek, Mark earned the nickname ``McSteamy'' for his good looks by the female interns.

Seattle Grace is later renamed Grey-Sloan Memorial Hospital in their memory.
