Their legacies are rich with innovation, memorable moments, and influential figures that have shaped the way we enjoy sports today. Let's delve into the legacy of some of the most notable closed sports leagues and explore how they continue to influence the sports world.

The All-American Girls Professional Baseball League (AAGPBL)

The league also played a significant role in popularizing slam dunks and high-flying, athletic basketball.

Legacy: Despite folding in 1976, the ABA's impact on basketball is undeniable. Four ABA teams—Indiana Pacers, San Antonio Spurs, Denver Nuggets, and New York Nets—were absorbed into the NBA, and many ABA players, such as Julius Erving (Dr. J), became NBA legends. The three-point line, which the NBA adopted from the ABA, has become a crucial aspect of modern basketball strategy. The ABA's influence on the entertainment value and style of basketball continues to be felt today.

The World Hockey Association (WHA)

Despite high initial ratings, the XFL struggled with quality of play and viewership, folding after just one season.

The league's emphasis on fan engagement and media integration influenced future attempts to create alternative football leagues.
