COMPETITION Back   The Fédération Internationale des Quilleurs oversees bowling internationally, and many national, regional, and local organizations sanction competitive bowling on lower levels. In the United States the American Bowling Congress (ABC), the Women's International Bowling Congress (WIBC), and the Young American Bowling Alliance (YABA) are the major groups that sponsor tournaments, organize clinics, and hold conventions to review rules. Amateurs make up the majority of bowling enthusiasts and combine to participate in more than 200,000 sanctioned leagues each year. They play on teams made up of friends, fellow church members, or coworkers. Many bowling centers sponsor leagues of varying skill and age levels, meaning that almost anyone can enjoy the sport. Professionals bowl as members of the Professional Bowlers Association (PBA) or the Ladies Pro Tour (LPBT). These organizations sponsor tournaments in cities across the United States and Canada. Professional bowlers also make instructive movies and videos, conduct clinics, and bowl in exhibition matches. Famous bowlers from the United States include Earl Anthony, Donna Adamek, Don Carter, Marion Ladewig, Betty Morris, Aleta Sill, Dick Weber, and Walter Ray Williams, Jr.
