As a staple of 1970s American television, the Tuesday-night medical drama Marcus Welby, M.D. ran for a respectable seven seasons (1969-76) on ABC. The program brought Father Knows Best star Robert Young back to television (six years after Father wrapped) as the titular physician, a Santa Monica-based general practitioner whose capacity for doctor-patient dedication pulled him out of the office and O.R. and into the personal affairs of many patients. Assisting Welby was the considerably younger and less-experienced Dr. Steven Kiley (James Brolin), who employed a by-the-book approach to medicine and therefore felt more than a little bit flummoxed by the psychiatric tendencies woven throughout Welby's treatment methods. This set presents both the initial two-hour telemovie that formed the basis of the series (aired on March 29, 1969) and the complete first season, with all 26 episodes as they originally aired.
