The second season has some visible changes. The opening and closing credits now have a slight outline. Next, the light fabric couch has been replaced with a brown leather one. Then, the entrance to the Drummond penthouse goes from a double to a single door. Lastly, Charlotte Rae (Edna Garrett) leaves the series mid season for "The Facts of Life" (1979) giving way for new housekeeper Adelaide Brubaker (Nedra Volz).
The show's theme song adds the ending "hmmm" to the closing credits until the end of the seventh season.
The first episode directed by Gerren Keith.
