The three-point rule in basketball was first introduced in 1961 by the American Basketball League (ABL), which was looking to add excitement to the game and distinguish itself from the NBA. The rule was first tested at the collegiate level in 1945, with a 21-foot line, in a game between Columbia and Fordham, but it was not kept. Over the next two decades, several collegiate conferences experimented with the three-point rule, with the NCAA's Southern Conference becoming the first to officially adopt it for the 1980-81 season. The NBA implemented the three-point shot league-wide for the 1979-80 season, and it has since become a permanent fixture, with the current 3-point line distance being universally adopted.

The three-point rule was first tested in 1945
The three-point rule in basketball was first tested in 1945, in a game between Columbia and Fordham. The three-point line was drawn at 21 feet, but it was not kept as a rule. The game saw the first-ever attempt at a three-pointer in basketball history, a concept that would go on to become a staple of the sport.
The three-point shot was introduced to add excitement to the game and encourage more offensive variety. Over the years, the three-point rule has sparked heated discussions, with critics arguing that it has made the game too one-dimensional, with teams prioritizing rim shooting over traditional post-play, mid-range shots, and inside scoring. Despite the criticism, the three-point shot remains an integral part of modern basketball, with teams shooting twice as many threes as they did a decade ago.
The three-point rule was tested again in 1958, this time with a 23-foot line, in a game between St. Francis (NY) and Siena. In 1961, Boston University and Dartmouth played a game with an experimental rule that counted all field goals as three points. The American Basketball League (ABL) became the first basketball league to officially institute the three-point rule in 1961, with the line set at 25 feet from the basket.
The NBA first implemented the three-point rule in the 1979-80 season, with the line at 23 feet 9 inches at the top of the key and 22 feet at the corners. The rule was introduced on a one-year trial basis but has since become permanent. The NCAA's Southern Conference became the first collegiate conference to use the three-point rule, adopting it for the 1980-81 season, with the line set at 22 feet. The three-point line was adopted across all college basketball conferences in the 1986-87 season, with the distance standardized to 19 feet 9 inches.

The American Basketball League was the first to institute the rule in 1961
The three-point rule in basketball was first instituted by the American Basketball League (ABL) in 1961. The ABL commissioner, Abe Saperstein, wanted to add excitement to the game and set his league apart from the NBA. He hoped that the three-pointer would become basketball's equivalent of the home run in baseball. Saperstein and DePaul University coach Ray Meyer used tape to determine the distance of the shot, settling on 25 feet from the basket. However, in June 1961, while Saperstein was travelling, the other ABL owners voted to shorten the distance to 22 feet.
The three-point rule was first tested in a collegiate game between Columbia and Fordham in 1945, with a 21-foot line, but it was not kept as a permanent rule. There were further one-game experiments in 1958 and 1961, with varying line distances. In 1962, St. Francis (New York) head coach Daniel Lynch suggested the idea of a three-point line to the New York Basketball Writers Association.
It wasn't until the 1979-80 season that the NBA implemented the three-point shot league-wide, initially on a one-year trial basis. This was the same season that Magic Johnson and Larry Bird made their rookie debuts. The introduction of the three-point shot was expected to significantly change the way NBA basketball was played, but this didn't happen immediately. Teams averaged less than three three-point shots per game during that first season.
Over time, the three-point shot has become an increasingly important part of the game. In recent years, there has been a sharp increase in the number of three-point attempts, with teams averaging about 37.5 three-pointers per game. This has sparked debates about whether the three-point line should be altered or abolished, with some critics arguing that the game has become too one-dimensional and predictable. Despite these discussions, the three-point shot remains a valuable weapon in modern basketball.

The NCAA's Southern Conference was the first collegiate conference to use the rule
The three-point rule in basketball has been a topic of much discussion and experimentation over the years, with different leagues adopting the rule at various times. The NCAA's Southern Conference was the first collegiate conference to officially implement the three-point rule, introducing it for the 1980-81 season. This conference set the three-point line at 22 feet (6.71 metres), and Ronnie Carr of Western Carolina made history by scoring the first-ever three-pointer in college basketball on November 29, 1980.
The adoption of the three-point rule by the NCAA's Southern Conference marked a significant milestone in the evolution of basketball. It demonstrated a willingness to innovate and adapt the rules of the game to create more exciting and dynamic play. This rule change also highlighted the potential benefits of a three-point line, which could add a new layer of strategy and scoring opportunities for teams.
Prior to the Southern Conference's decision, there had been several experiments with a three-point line in collegiate basketball. As early as 1945, a 21-foot line was tested in a game between Columbia and Fordham, but it was not adopted as an official rule. Similar one-game experiments took place in 1958 and 1961, with varying line distances, but it wasn't until the Southern Conference's decision that the three-point rule gained traction in collegiate basketball.
Following the Southern Conference's lead, other NCAA conferences began to experiment with the three-point rule over the next five years, with different distances for the three-point line being utilised. It was only in 1986 that the NCAA standardised the rule across all college basketball conferences, setting the three-point line at 19 feet 9 inches (6.02 metres) for the 1986-87 season. This standardisation brought consistency to collegiate basketball and allowed for a fair comparison of scoring achievements across different conferences.
The impact of the three-point rule extended beyond the collegiate level, influencing the strategies and playing styles of professional leagues like the NBA. Over time, the three-point shot has become an integral part of basketball, with teams relying on it more frequently and players developing specialised skills to excel from beyond the arc. However, this evolution has also sparked debates about potential rule changes to maintain a balance in the game and encourage a diverse range of offensive strategies.

The NBA implemented the rule in the 1979-80 season
The NBA implemented the three-point rule in the 1979-80 season, marking a significant shift in the sport's history. Prior to this, the idea of a three-point shot was practically unheard of in the NBA, with teams focusing on scoring near the basket and taking higher-percentage shots closer to the hoop. The introduction of the three-point line was intended to address the league's dwindling popularity and add excitement to the game.
The American Basketball League (ABL) was the first to introduce the three-point rule in 1961, with commissioner Abe Saperstein aiming to distinguish the league from the NBA. The NCAA's Southern Conference became the first collegiate conference to adopt the rule, implementing a 22-foot line for the 1980-81 season. Ronnie Carr of Western Carolina made history by scoring the first three-pointer in college basketball on November 29, 1980.
During the 1979-80 season, the NBA's three-point line was set at 23 feet, 9 inches at the top of the key, and 22 feet at the corners. The introduction of the three-point shot did not immediately revolutionize the game as some had expected. NBA teams averaged less than three three-point attempts per game during that inaugural season. However, over time, the three-pointer has become an integral part of NBA strategy, with teams increasingly prioritizing long-range shooting.
The impact of the three-point rule is evident in the modern game, with teams now averaging around 37.5 three-point attempts per game. This dramatic increase has sparked debates about potential rule changes to encourage more offensive variety. Critics argue that the game has become too reliant on three-point shooting, making it less exciting and predictable. Despite these concerns, the three-point shot remains a valuable weapon in modern basketball, and the rule has been permanently adopted by the NBA.

The three-point rule has sparked debates about altering or abolishing it
The three-point rule was first introduced in 1961 by the American Basketball League (ABL), which was dealing with dwindling popularity at the time. The ABL's commissioner, Abe Saperstein, wanted to add excitement to the game and differentiate it from the NBA. The three-point rule was first tested at the collegiate level in 1945, with a 21-foot line, in a game between Columbia and Fordham, but it was not kept as a rule.
Over the years, the three-point rule has sparked debates about altering or abolishing it. Critics argue that the game has become too one-dimensional, with teams prioritizing rim shooting over traditional post-play, mid-range shots, and inside scoring. The introduction of the three-point rule was expected to bring about a fundamental shift in the way NBA basketball was played. Franklin Mieuli, the then-owner of the Golden State Warriors, called the rule change "immoral," predicting that the NBA would suffer a fate similar to the ABA and that the shot would detract from the team aspect of the game.
Some fans and analysts believe that the constant barrage of three-pointers has made the game less exciting and too predictable, leading to discussions about rule changes that could promote more offensive variety. Suggestions have included moving or removing the three-point line, changing the scoring system, limiting the number of three-point shots, remodeling the court, or allowing hand-checking behind the arc.
However, despite the debate, the three-point shot remains the most valuable weapon in modern basketball. Teams are shooting twice as many threes as they were 10 years ago, and almost three times as many as 20 years ago. The three-point rule has had a significant impact on the game, with well-timed threes having the potential to change a team's fate.
