The Argentine Football Association (AFA) was formed in 1893, and is the eighth oldest national football association in the world. The AFA today counts 3,377 football clubs, including 20 in the Premier Division. Since the AFA went professional in 1931, fifteen teams have won national tournament titles, including River Plate with 33 and Boca Juniors with 24. Over the last twenty years, futsal and beach football have become increasingly popular. The Argentine national beach football team was one of four competitors in the first international championship for the sport, in Miami in 1993.
