Many grammar schools, youth groups, municipal recreation centres, churches, and other organizations conduct basketball programs for youngsters of less than high school age. Jay Archer, of Scranton, Pennsylvania, introduced “biddy” basketball in 1950 for boys and girls under 12 years of age, the court and equipment being adjusted for size. In the early years the number of players on a team varied according to the number in the class and the size of the playing area. In 1894 teams began to play with five on a side when the playing area was less than 1,800 square feet (167.2 square metres); the number rose to seven when the gymnasium measured from 1,800 to 3,600 square feet (334.5 square metres) and up to nine when the playing area exceeded that.
