Birth of the 'Three-Point Line'

The three-point line has a surprisingly messy origin story. It started with a 1945 experiment at a Columbia vs. Fordham game, where some players literally forgot to dribble. Coach Howard Hobson proposed it to offset big men's dominance, and the ABL officially adopted it in 1961. Abe Saperstein then fought to keep it at 25 feet. The NBA didn't follow until 1979. There's plenty more to this story if you keep going.

Key Takeaways

• Basketball's first three-point line experiment occurred in 1945, when Columbia hosted Fordham under a rule awarding three points for shots beyond 21 feet.
• Howard Hobson proposed the three-point shot to offset dominant big men, mathematically justifying three points as 50% more value for longer-range attempts.
• The American Basketball League became the first professional league to adopt the three-point line in 1961, placing the arc at 25 feet.
• Abe Saperstein and DePaul coach Ray Meyer selected the 25-foot distance through intuitive experimentation, aiming to reward smaller players and create crowd-pleasing moments.
• The ABA made the three-pointer central to its identity in 1967, with Commissioner George Mikan championing the rule to give smaller players scoring opportunities.

The First Three-Point Line Experiment Happened in 1945

On February 7, 1945, Columbia hosted Fordham at its Morningside Heights gym, where roughly 1,000 spectators watched basketball's first three-point line experiment unfold. The experimental rule awarded three points for shots beyond 21 feet, and Columbia won 73–58. Columbia hit 11 three-pointers while Fordham made 9, though players occasionally forgot to dribble, triggering traveling violations.

The first three-point line experiment reactions were mixed. Post-game survey results showed 148 fans favored the rule while 105 opposed it. The New York Times criticized it for undermining team play, and the Columbia Spectator highlighted on-court confusion. An Associated Press writer questioned the need, asking, "What's wrong with the old game?" Experts predicted the rule would die naturally, and it wasn't adopted permanently — at least not yet. Another experiment followed in 1958, when St. Francis and Siena played a game featuring a 23-foot three-point line, demonstrating that innovators continued to push the concept forward. It wasn't until 1961 that the American Basketball League officially implemented the three-point line as a rule, marking the first time the concept was formally adopted by a professional basketball organization.

Why Howard Hobson Proposed the Three-Point Shot

Howard Hobson didn't just stumble onto the idea of the three-point shot — he built it from years of careful observation. Hobson's statistical analysis revealed clear reasons for change:

1. Shots beyond 21 feet connected only 18.6% of the time versus 29.4% closer in
2. Hobson's offset height advantage goal aimed to reward distance shooters over dominant big men
3. Basket congestion from 10 players in tight spaces increased illegal defenses and physical contact
4. Longer shots deserved 50% more value, making three points mathematically justified

You can see how his reasoning wasn't arbitrary — every element connected to real data. He wanted a smarter, safer, more balanced game where height alone couldn't dictate outcomes and floor spacing would naturally open up play. Hobson also believed the three-point shot would help resurrect the two-hand set shot as a vital part of basketball's offensive arsenal, a style that had faded as the one-handed shot took over. To put his theories to the test, Hobson arranged a landmark game between Columbia and Fordham on February 07, 1945, where the three-point line and other rule changes were officially trialed.

The ABL Beat Everyone to the Three-Point Line in 1961

While Howard Hobson was laying the statistical groundwork for the three-point shot, a scrappy upstart league had already beaten everyone to the punch. The American Basketball League (ABL), formed in 1961 by Abe Saperstein and Paul Cohen, became the first professional league to adopt the three-point field goal. Saperstein's three-point line vision placed the arc at a 25-foot radius from the basket, rewarding players who could consistently shoot from distance.

The ABL's pioneering rules didn't stop there. The league also introduced a 30-second shot clock and an 18-foot free throw lane. Though the ABL folded on December 31, 1962, its influence proved lasting. The ABA followed with its own three-pointer in 1967, and the NBA finally adopted it in 1979. Saperstein had originally been motivated to form the ABL after being denied the Los Angeles NBA franchise, which was instead awarded to the relocated Minneapolis Lakers. Notably, when the ABA later merged with the NBA in 1976, the three-point line was not included as part of the agreement, delaying its adoption by three more years.

Why Abe Saperstein Picked 25 Feet for the Three-Point Line

The ABL's adoption of the three-point line raised an obvious question: why 25 feet?

Saperstein and DePaul coach Ray Meyer grabbed a tape measure and practiced pure intuitive distance selection. Their process was straightforward arbitrary experimentation—no science, no data.

They settled on four guiding goals:

1. Reward smaller players competing against taller opponents
2. Create basketball's equivalent of a baseball home run
3. Generate spectacular, crowd-pleasing moments
4. Distinguish the ABL from the NBA

When other owners voted 4-3 to shorten the line to 22 feet, Saperstein ignored them, leveraging his Globetrotters ownership power to maintain 25 feet.

He later added a 22-foot corner line, addressing balance issues with the uniform arc—ultimately producing the foundation for today's familiar three-point standard. The concept would eventually reach the NBA, where Chris Ford made the first official three-pointer when the league adopted the line in the 1979-80 season. Before the ABL, the three-point line had already been tested at the collegiate level in 1945 with a 21-foot line, demonstrating that the idea had been circulating in basketball circles for years.

The ABA Made the Three-Pointer Part of Its Identity

When the ABA launched its inaugural 1967-68 season, it didn't just borrow the three-point line from the ABL—it made the shot central to its identity. Commissioner George Mikan championed the rule as a way to give smaller players creative scoring opportunities in a game dominated by big men.

That vision drove a player driven game evolution, opening defenses and boosting guards who couldn't overpower opponents in the paint. Fans responded enthusiastically, embracing the spectacle of long-range shots that carried the same excitement as a baseball home run.

The three-pointer gave the ABA a distinct style that rivaled the NBA's approach, turning high-scoring, dynamic play into the league's calling card and proving the shot's value long before the NBA ever adopted it. The ABA folded in 1976, leaving the NBA as the sole major professional basketball organization to carry the three-point line's legacy forward. The NBA ultimately embraced the innovation, adopting the 3-point shot in 1979, marking a turning point that would forever change the strategy and style of professional basketball.

When Did the NBA Finally Add the Three-Point Line?

Despite the ABA's decade-long showcase of the three-pointer's appeal, the NBA didn't adopt it until the 1979-80 season—three years after absorbing four ABA franchises in the 1976 merger. The initial reaction to the three-point line was skeptical, with owners calling it "immoral" and coaches dismissing it as a gimmick.

Here's what defined its debut:

1. Chris Ford hit the first NBA three-pointer on October 12, 1979.
2. Teams averaged just 2.8 attempts per game that first season.
3. Magic Johnson and Larry Bird both began their rookie seasons simultaneously.
4. The line measured 23 feet 9 inches at the top, 22 feet in corners.

The impact of the three-point line on game strategy took years to fully materialize, as attempts didn't climb noticeably until the late 1980s. Notably, even Michael Jordan struggled with three-point shooting early in his career before eventually improving his range.

Who Made the First Three-Pointer in NBA History?

On October 12, 1979, Chris Ford—a guard for the Boston Celtics—stepped up and made history by sinking the NBA's first official three-pointer against the Houston Rockets at Boston Garden. You can picture the moment: a clean swish from the right wing, 23 feet and 9 inches out, sparking an immediate team celebration.

Chris Ford's iconic shot marked the official debut of the three-point line in a game the Celtics dominated 128-102. Ford went on to attempt 25 three-pointers that season, hitting 7 for a 28% clip. While modest by today's standards, the three-point line's impact on basketball proved enormous, inspiring future sharpshooters like Larry Bird and Drazen Petrovic and permanently reshaping how the game is played at every level.

Why the NBA Shortened the Three-Point Line: Then Put It Back

The league's fix? Shorten the line to a uniform 22 feet for three seasons (1994–97). Here's what happened:

1. Three-point attempts jumped from 9.9 to 15.3 per game immediately.
2. Shooters set records, yet overall field goals actually dropped.
3. Reduced spacing crushed the impact on offensive gameplay near the paint.
4. Driving lanes tightened, making offense harder, not easier.

After three seasons, the NBA reverted to 23'9". Accuracy stabilized around 35–36%, spacing improved, and scoring eventually climbed five points per game by 2010–11.

How the NCAA and FIBA Set Their Own Three-Point Lines

While the NBA was busy tweaking its own line, the NCAA and FIBA were charting independent paths toward standardization—each at their own pace. FIBA introduced its line in 1984 at 6.25 meters, debuting it at the 1988 Seoul Olympics before extending it to 6.75 meters.

The NCAA's distance adoption timeline began universally in 1986–87 at 19 feet 9 inches for men. NCAA women's line changes mirrored men's closely—experimental in 1986–87, mandatory by 1987–88. Both programs advanced to 20 feet 9 inches in 2008–09, then reached 22 feet 1¾ inches in 2019–20, finally aligning with FIBA's international standard. You can trace today's unified distance directly back to decades of independent experimentation that gradually pulled these governing bodies toward a common measurement.

Despite the line's evolution, its introduction was far from universally celebrated—in the first full season, teams attempted just 9.2 three-pointers per game, reflecting the widespread skepticism coaches held toward the new rule. Among the early adopters who embraced the shot was future NBA head coach Scott Brooks, who gained an advantage because the Pacific Coast Athletic Association had already introduced the three-point line a year earlier in 1985.

How Three-Point Attempts Grew From 3 to 35 per Game

When the NBA introduced the three-point line in 1979, teams averaged just 2.8 attempts per game—a figure so modest it barely registered as a tactical consideration.

Tactical shifts post-2014 accelerated growth dramatically. Consider this progression:

1. 1979: 2.8 attempts per team per game
2. 1998–2012: Three-point share grew only 7% over 14 years
3. 2014–2018: Attempts surged 8%, exceeding the prior 14-year total
4. 2016–2017: Teams averaged 27 attempts per game

The volume potential of records reinforces this explosion—Klay Thompson attempted 24 threes in a single game, making 14. Today, Luka Dončić averages 10.8 attempts per game individually. What once seemed like an afterthought now defines modern offensive strategy at every level of basketball.

Chris Ford made the very first three-pointer in NBA history on October 12, 1979, a moment that few could have predicted would ignite a revolution fundamentally reshaping how the sport is played and coached. Among today's most prolific shooters, LaMelo Ball ranks second in three-point attempts per game, launching 9.8 attempts per contest behind only Dončić.
