The Battle of the Sexes is a game where male and female contestants challenge each other on trivia questions.
The principle of the game is to demonstrate the imbalance between male and female genders as they compete.
The concept spread to Austereo's affiliated radio stations across Australia, including FOX FM's Tracy Bartram and Matt Tilley.
In 1998, the concept was adapted into a short-lived television show on Network Ten hosted by Ed Phillips.
It has also been adopted by MTV, uniting cast members from The Real World and Road Rules for a chance at money.
