Doc is an American sitcom produced by MTM Enterprises which aired on CBS[1] from August 16, 1975, to October 30, 1976.

On Doc, actress Elizabeth Wilson costarred with Hughes as Joe's wife Annie, Judith Kahan as his daughter Laurie, John Harkins as Laurie's husband, and Mary Wickes as Joe's nurse, Tully.

When it returned in the fall of 1976, the format had been substantially changed, with Dr. Bogert now a widower, working at a down-and-out city clinic.

Mary Wickes was the only other cast member from the first season to remain,[3] but she departed after the first episode.

Shortly after the series ended, Hughes returned to The Bob Newhart Show to guest-star in a Christmas episode in December 1976.
