The Church News reports that 3,500 teams and 50,000 players are involved in an all-church basketball tournament. For the final playoffs the teams come to Salt Lake City from throughout the United States, Canada, and Mexico. Basketball is the most popular of the all-church team sports which also includes softball and volleyball. However, from 1958 to 1971 more than thirty stakes have been organized outside of North America, and their youth obviously cannot participate in such tournaments. In 1971 church headquarters ends the "all-Church" sports competitions.
