The American Basketball Association (ABA) was a professional basketball league that operated from 1967 to 1976. It was known for its innovative style of play, including the introduction of the three-point line and a focus on fast-paced, high-scoring games. The league featured several teams, including the Indiana Pacers and the New Jersey Nets, and attracted many talented players. In 1976, the ABA merged with the National Basketball Association (NBA), leading to the absorption of four ABA teams into the NBA. The merger helped to elevate the popularity of professional basketball in the United States and contributed to the growth of the sport overall.
