How a flashy, red-white-and-blue basketball league forced the NBA to change forever
In short: Operating from 1967 to 1976, the American Basketball Association was more than a rival league. With its three-point shot, slam dunk contests, and aggressive player recruitment, the ABA forced the established NBA to modernize. Though the ABA eventually folded, its innovations and legacy remain embedded in professional basketball today.
The ABA was born from a desire to challenge the NBA’s dominance, which at the time consisted of only 12 teams. Conceived by marketing executives and sports enthusiasts, the league aimed to capture markets the NBA ignored, particularly in the American Southeast. From its inception, the ABA distinguished itself with a wide-open, high-scoring style of play. It introduced the three-point field goal, a 30-second shot clock, and a signature red, white, and blue ball, all of which contrasted sharply with the NBA’s more traditional approach.
Beyond its aesthetic, the ABA fundamentally shifted the power dynamics of professional basketball. It pioneered the 'hardship exemption,' allowing players like Spencer Haywood to turn professional before completing four years of college, a policy that eventually evolved into the modern 'one-and-done' rule. Furthermore, the league’s willingness to pay players through innovative annuity plans and its aggressive pursuit of talent—including players blackballed by the NBA—forced a bidding war that significantly boosted professional salaries across the sport.
The league’s end came in 1976, when it merged with the NBA. While only four teams—the Indiana Pacers, Denver Nuggets, San Antonio Spurs, and New York Nets—were absorbed into the NBA, the ABA’s influence persisted. The NBA adopted the three-point line in 1979 and later integrated the slam dunk contest, which the ABA had debuted at its final All-Star Game in 1976. Today, while the NBA does not officially include ABA statistics in its record books, the Basketball Hall of Fame recognizes the league’s history, acknowledging its role in shaping the modern game.
