At the 9th Academy Awards ceremony held in 1937, Gale Sondergaard was the first winner of this award for her role in "Anthony Adverse". Initially, winners in both supporting acting categories were awarded plaques instead of statuettes. Beginning with the 16th ceremony held in 1944, winners received full-sized statuettes. Currently, nominees are determined by single transferable vote within the actors branch of AMPAS; winners are selected by a plurality vote from the entire eligible voting members of the Academy.
