Men's basketball games are divided into halves rather than quarters, with two 20-minute halves making up the game. This is in contrast to women's college basketball, which is divided into four 10-minute quarters. Men's college basketball is the only level of basketball in the world that does not use quarters, and there has been much debate over whether it should be changed. The format of halves was first outlined by Dr James Naismith, the creator of basketball, in 1891.

Men's college basketball is the only form of basketball without quarters
Men's college basketball is unique in that it is played in halves rather than quarters. The game of basketball was created in 1891 by Dr. James Naismith, who stated in his original rule book that it should be "played in two fifteen-minute halves with rest time in between". In 1905, the rules were adjusted to feature two twenty-minute halves.
From the 1951-52 season to the 1954-55 season, men's college basketball was played in four ten-minute quarters, the same format used in the NBA. However, in 1954, the NCAA reverted to playing in halves, while the NBA kept the new four-quarter format, extending each quarter to twelve minutes.
The decision to revert to halves in men's college basketball was likely made to increase competitiveness, as longer halves mean less stoppage time during the game, leading to more scoring opportunities and a steadier pace and flow. This format also allows for closer games between a wider range of teams.
Despite the benefits of the current format, there have been calls for men's college basketball to switch to quarters, bringing it in line with other forms of basketball. ESPN's Jay Bilas, for example, has argued for the introduction of quarters, stating that men's college basketball is the "only visible form of the game in the world that does not have quarters". College coaches have also favoured the change, expressing concerns that the current format allows for games to be stalled by one team holding the ball due to the lack of a shot clock.

Men's basketball games are split into two 20-minute halves
Men's basketball games, specifically at the college level, are split into two 20-minute halves. This is in contrast to the women's game, which is divided into four 10-minute quarters. The difference in format between the men's and women's games is a notable aspect of NCAA basketball tournaments.
The game of basketball was invented by Dr. James Naismith in 1891. In his original rule book, Naismith stated that basketball games should be "played in two fifteen-minute halves with rest time in between". However, it was soon realised that this wasn't long enough for a high-scoring, competitive game. So, in 1905, the rules were adjusted to feature two 20-minute halves, which is still the format used in men's college basketball today.
There has been much debate about the advantages of halves versus quarters in NCAA basketball. Some argue that the longer halves in men's college basketball create a more competitive game by allowing for less stoppages, more scoring opportunities, and a steadier pace and flow. On the other hand, quarters can reduce the number of foul calls and provide more bonus opportunities with free throws. The four-quarter format also aligns with other forms of basketball, such as the NBA, WNBA, and FIBA, and some believe that men's college basketball should follow suit.
Despite the ongoing debate, the NCAA men's game has retained its two-half structure, while the women's game shifted to quarters in 2015. This change was implemented by the NCAA Women's Basketball Rules Committee, who believed that four quarters would improve the flow of the game. As a result, the women's game now has distinct rules regarding team fouls and free throws, which differ from the men's game.

Women's college basketball has four 10-minute quarters
Men's college basketball games are played in two halves, whereas women's college basketball games are played in four 10-minute quarters. This change was approved by the NCAA Playing Rules Oversight Panel in 2015, and it applied to the 2015-16 season. The NCAA Women's Basketball Rules Committee proposed the switch to quarters, believing it would improve the flow of the game.
The game of basketball was invented in 1891 by Dr. James Naismith, who stated in the original rule book that games should be "played in two fifteen-minute halves with rest time in between". In 1905, the rules were adjusted to feature two 20-minute halves, and this format is still used in men's college basketball today.
However, in 1951, the rules changed again, this time introducing four 10-minute quarters for both the NBA and NCAA. This format was short-lived for the NCAA, as they reverted to playing halves in 1954, while the NBA kept the four-quarter structure but extended each quarter to 12 minutes.
The decision to keep men's college basketball games in two halves while women's games are played in four quarters is largely down to the governing bodies of each organisation. Some have suggested that the difference in formats helps each organisation to distinguish its own "brand" of basketball.
There has been much debate about the advantages and disadvantages of halves versus quarters in NCAA basketball. Some argue that quarters create a more competitive game with less stoppage time, while others believe that halves create a better flow and allow for more scoring opportunities.

Men's basketball previously had 10-minute quarters from 1951-52 to 1954-55
Men's basketball has had a long and varied history, with several changes to the structure of the game over the years. One notable variation occurred between 1951 and 1955, when the game transitioned from the traditional two-halves format to four 10-minute quarters. This change was implemented for the 1951-52 season and remained in place until the 1954-55 season.
The game of basketball was created in 1891 by Dr. James Naismith, who outlined in his original rule book that the game would consist of "two fifteen-minute halves with rest time in between". This format was adjusted in 1905, resulting in two 20-minute halves for Men's NCAA basketball. However, in a significant shift, the rules were changed again in 1951, introducing four 10-minute quarters for both the NBA and NCAA.
This change to four-quarter gameplay lasted for a brief period, from the 1951-52 season until the 1954-55 season. During this time, men's basketball embraced a format that is more commonly associated with the women's game today. Interestingly, the NBA continued to embrace the four-quarter structure but extended each quarter to 12 minutes, a format that remains in place today.
The return to two longer halves in men's college basketball was influenced by the desire to enhance competitiveness. Longer halves mean fewer stoppages, allowing for more scoring opportunities and a steadier pace. This format also enables a wider range of teams to compete more closely with each other. Despite the reversion to halves, the one-and-one" free-throw rule, introduced in the 1954-55 season, remained, allowing players to attempt a second free throw after a foul if they made the first.

There are debates about whether men's basketball should adopt a four-quarter format
There are ongoing debates about whether men's college basketball should adopt a four-quarter format, with some arguing that it would improve the flow of the game and make it more competitive. Currently, men's college basketball games consist of two 20-minute halves, with a halftime intermission of 15 minutes. On the other hand, women's college basketball games are played in four 10-minute quarters, also with a 15-minute halftime intermission.
ESPN's Jay Bilas has been a prominent advocate for the four-quarter format in men's college basketball. He argues that it would bring men's college basketball in line with every other form of basketball worldwide, which all use quarters. Additionally, Bilas suggests that the four-quarter format could enhance the competitiveness of the game by reducing the number of stoppages. This is because, in the quarters system, team fouls are reset at the end of each quarter, leading to fewer bonus opportunities with free throws.
However, the four-quarter format is not without its critics. Some argue that having more breaks in the game could be counterproductive to the goal of reducing stoppage time. The current two-half format in men's college basketball allows for a steadier pace and flow, with more scoring opportunities and closer games. This format also aligns with the original rules of basketball, as envisioned by its creator, Dr. James Naismith, in 1891.
The decision to stick with the two-half format or switch to the four-quarter format involves various factors, including the preferences of spectators, coaches, and governing bodies. While some college coaches have expressed concerns about the lack of a shot clock, others have pointed out that the two-half format allows for more media timeouts, which can be important for revenue generation. Ultimately, the choice between the two formats remains a subject of ongoing discussion and debate within the basketball community.
