At first, there was considerable controversy about the sport, because the players were of both sexes. Several sports journalists refused to pay even the slightest attention to the new sport. Korfball players were accused of being immoral. Even the sportswear was criticised, because the women were showing bare knees and ankles; one newspaper wrote that "Korfball is a monster that spreads its claws to all sides." Yet korfball was featured as a demonstration sport in the Summer Olympics of 1920 and 1928.
