Men's college basketball games have two halves
Men's college basketball games are currently played in halves, rather than quarters. This is in contrast to women's college basketball, which is played in quarters.
The decision to play men's college basketball games in halves goes all the way back to the game's original rulebook, written by Dr. James Naismith in 1891. In it, Naismith stated that basketball should be played in ""two 15-minute halves with rest time in between". In 1905, the rules were adjusted to the current format of two 20-minute halves.
In 1951, the rules were changed again, this time to four 10-minute quarters, for both the NBA and NCAA. However, in 1954, the NCAA reverted to playing in halves, while the NBA kept the new four-quarter rule, adding two minutes to each quarter.
There are several theories as to why the NCAA switched back to halves. One is that longer halves mean less stoppage during a game, leading to more scoring opportunities, a steadier pace and flow, and closer games between a wider range of teams. Another theory is that the two-half system creates a unique rhythm that only men's college basketball has.
There has been some discussion about whether men's college basketball should switch back to quarters. In 2023, ESPN's Jay Bilas said:
> "How can the game be better? By changing some of its archaic rules. First, men's college basketball needs to go to four 10-minute quarters. Right now, this is the only level of basketball in the entire world that does not have quarters."

Women's college basketball games have four quarters
Women's college basketball games are played in four quarters, while men's college basketball games are played in two halves. This change in format for women's college basketball was approved by the NCAA Playing Rules Oversight Panel in 2015. The primary objective of this transition was to enhance the flow and excitement of the game by increasing the pace of play and creating a more dynamic and engaging experience for both players and fans.
The adoption of the quarter format also led to a reduction in the number of media timeouts, with one scheduled for each quarter in televised games. Proponents of the change argued that it could lead to a steadier pace, increased scoring opportunities, and closer-contested endings. Additionally, the quarter format aligns women's college basketball with the top professional organizations in the sport for female athletes, such as the WNBA and FIBA.
The rules regarding team fouls and bonuses have also been impacted by the transition to quarters. In the previous half format, a team reached the "1:1 Bonus" when their opponents committed seven fouls per half, allowing the fouled player to get one free throw or two if they made the first. Once a team reached ten fouls, the opposing team moved to the "Double Bonus," earning two free throws for each subsequent foul. With the new quarter format, team fouls reset at the start of each quarter, and teams now reach the bonus and shoot two free throws on the fifth team foul in each quarter.
The debate between halves and quarters in basketball has been ongoing, with proponents of both formats presenting various arguments. Some believe that playing in halves makes the game more competitive due to longer continuous play and fewer stoppages. However, others prefer the quarter format for its potential to enhance the pace, dynamics, and excitement of the game. The decision to transition women's college basketball to a four-quarter format considered a multifaceted set of these considerations.

The NBA has four 12-minute quarters
Basketball games can be divided into halves or quarters, with the rules varying across different leagues and organisations. While men's college basketball games are split into two halves, the NBA has four 12-minute quarters.
The NBA's four-quarter format was introduced in 1951, when the league changed the format from two halves to four 10-minute quarters. However, in 1954, the NBA decided to keep the four-quarter format and extended each quarter to 12 minutes. This change resulted in the current format of four 12-minute quarters that the NBA still uses today.
The four-quarter format in the NBA has several implications for the game, particularly regarding team fouls and free throws. In the NBA, teams shoot two free throws after committing five fouls, and the foul count resets at the end of each quarter. This format encourages a faster-paced game with more scoring opportunities.
The NBA's four-quarter format also aligns with other professional basketball leagues, such as the WNBA and FIBA, which also use the same format. This consistency in the rules across professional leagues provides a seamless transition for players moving from the college level to the professional ranks.
While the NBA has stuck with the four-quarter format, there have been discussions and suggestions about possible changes. For example, NBA commissioner Adam Silver has proposed the idea of returning to 10-minute quarters, citing the benefits of a two-hour game format for modern television habits. However, as of now, the NBA continues to use the four 12-minute quarters format for its games.

Fouls and free throws are impacted by halves vs quarters
The number of quarters or halves in a basketball game varies depending on the league and level of play. For example, while NCAA Men's Basketball is played in two halves, Women's College Basketball, the WNBA, and the NBA are played in four quarters.
The difference between halves and quarters has a significant impact on fouls and free throws. In the NCAA, a team reaches the "1:1 Bonus" when their opponents commit seven fouls per half. This means that for each subsequent foul, the fouled player gets one free throw, and if they make that free throw, they get a second one. Once a team reaches ten fouls, the opposing team moves to the "Double Bonus", meaning they get two free throws for each subsequent foul. On the other hand, in the NBA, which is played in quarters, teams shoot two free throws after five fouls, which reset at the end of each quarter.
The number of quarters or halves can also affect the strategy employed by teams. For instance, in the NBA, the "Hack-a-Shaq" strategy involves a losing team deliberately fouling a poor free-throw shooter on the opposing team until the two-minute mark, after which they switch to playing intense defense. This strategy aims to extend the game and potentially close the gap in the score.
The impact of halves versus quarters on fouls and free throws also depends on the specific rules and regulations of each league. For example, in FIBA and NCAA women's basketball, the fouled player shoots two free throws starting with the opponent's fifth foul in a period, whereas in NCAA men's basketball, one free throw is awarded starting with the seventh foul of the half, and two free throws are awarded starting with the tenth foul.
In summary, the number of quarters or halves in a basketball game directly influences the strategy employed by teams, the pace and flow of the game, and the number of stoppages. The specific rules regarding fouls and free throws can vary between leagues, but the fundamental difference between halves and quarters lies in the frequency of stoppages and the accumulation of fouls.

Halves vs quarters debate affects game flow and competitiveness
The debate over halves versus quarters in basketball has implications for game flow and competitiveness, with variations in rules and gameplay across different leagues and levels.
In terms of game flow, the number of stoppages during a game is influenced by the use of halves or quarters. Longer halves result in fewer stoppages, leading to a steadier pace and flow. In contrast, quarters provide more opportunities for clock stops and strategic adjustments, particularly with the inclusion of quarter breaks as "media timeouts". This can impact the overall duration of the game, with more stoppages potentially extending the game time.
The debate also affects the competitiveness of the game, particularly in relation to scoring opportunities and team fouls. Longer halves, as seen in men's college basketball, allow for more scoring chances and a potentially higher-scoring game. Additionally, the accumulation of team fouls and the resulting free throws can impact the competitiveness and flow of the game. In the halves format, the 1:1 Bonus rule comes into effect when a team reaches a certain number of fouls per half, resulting in more free throws and potential disruptions to the game flow. On the other hand, the quarters format resets team fouls at the start of each quarter, and a team reaches the bonus with fewer fouls, reducing the number of free throws and encouraging a smoother game flow.
The choice between halves and quarters also influences the transition for players between different levels of the game, such as from college to professional leagues. The women's game, which adopted the quarters format, now aligns more closely with professional leagues like the WNBA and FIBA, offering a seamless transition for players advancing in their careers.
While men's college basketball has traditionally stuck to halves, there have been suggestions and experiments with the quarters format. In 1951, both college basketball and the NBA temporarily switched to quarters before the NCAA reverted to halves in 1954 due to concerns about game stalling without a shot clock. More recently, there have been proposals to adopt shorter quarters in the NBA to align with modern television habits and create a consistent two-hour game format.
The halves versus quarters debate continues to fuel discussions among fans, coaches, and players, with each side presenting valid arguments for their preferred format. The choice between halves and quarters ultimately influences the strategic options, scoring dynamics, and overall flow of the game, shaping the competitive landscape of basketball across different leagues and levels.
