The holder of the crown was determined in a lingerie battle royal on June 19, 2002, which aired on June 26, 2002. The participants in the match were Alexis Laree, Elektra, Erin Bray, Francine, Miss Joni, Sasha, Shannon, Taylor Vaughn, and Teresa Tyler. Vaughn last eliminated Elektra to win the crown. The TNA Knockout of the Year is another award in TNA given to the knockout who achieved the most or had the best run that year.
