Note: The names of award categories have changed dramatically through the years. Where the difference is significant, the actual title is cited in parentheses below. If the series also won another major program award — like Outstanding New Series, back in the days when there was such a category — it’s also noted. Missing years indicate that the award categories were dropped.
