^Certain award groups do not simply award one winner. They acknowledge several different recipients, have runners-up, and have third place. Since this is a specific recognition and is different from losing an award, runner-up mentions are considered wins in this award tally. For simplification and to avoid errors, each award in this list has been presumed to have had a prior nomination.
