The first two seasons were co-sponsored by Winston cigarettes and the characters appeared in several black and white television commercials for Winston (dictated by the custom, at that time, that the star(s) of a TV series often "pitched" their sponsor's product in an "integrated commercial" at the end of the episode).[citation needed] @Curionic
