Rules and regulations

Measurements and time limits discussed in this section often vary among tournaments and organizations; international and NBA rules are used in this section.

The object of the game is to outscore one's opponents by throwing the ball through the opponents' basket from above while preventing the opponents from doing so on their own. An attempt to score in this way is called a shot. A successful shot is worth two points, or three points if it is taken from beyond the three-point arc which is 6.25 meters (20 ft 6 in) from the basket in international games and 23 ft 9 in (7.24 m) in NBA games.

Playing regulations

Games are played in four quarters of 10 (international) or 12 minutes (NBA). College games use two 20 minute halves while most high school games use eight minute quarters. Fifteen minutes are allowed for a half-time break, and two minutes are allowed at the other breaks. Overtime periods are five minutes long. Teams exchange baskets for the second half. The time allowed is actual playing time; the clock is stopped while the play is not active. Therefore, games generally take much longer to complete than the allotted game time, typically about two hours.

Five players from each team (out of a twelve player roster) may be on the court at one time. Substitutions are unlimited but can only be done when play is stopped. Teams also have a coach, who oversees the development and strategies of the team, and other team personnel such as assistant coaches, managers, statisticians, doctors and trainers.

For both men's and women's teams, a standard uniform consists of a pair of shorts and a jersey with a clearly visible number, unique within the team, printed on both the front and back. Players wear high-top sneakers that provide extra ankle support. Typically, team names, players' names and, outside of North America, sponsors are printed on the uniforms.

A limited number of time-outs, clock stoppages requested by a coach for a short meeting with the players, are allowed. They generally last no longer than one minute unless, for televised games, a commercial break is needed.

The game is controlled by the officials consisting of the referee ("crew chief" in men's college and the NBA), one or two umpires ("referees" in men's college and the NBA) and the table officials. For college, the NBA, and many high schools, there are a total of three referees on the court. The table officials are responsible for keeping track of each teams scoring, timekeeping, individual and team fouls, player substitutions, team possession arrow, and the shot clock.

Equipment

Traditional eight-panel basketball

The only essential equipment in basketball is the basketball and the court: a flat, rectangular surface with baskets at opposite ends. Competitive levels require the use of more equipment such as clocks, scoresheets, scoreboard(s), alternating possession arrows, and whistle-operated stop-clock systems.

An outdoor basketball net.

A regulation basketball court in international games is 28 by 15 meters (approx. 92 by 49 ft) and in the NBA is 94 by 50 feet (29 by 15 m). Most courts are made of wood. A steel basket with net and backboard hang over each end of the court. At almost all levels of competition, the top of the rim is exactly 10 feet (3.05 m) above the court and 4 feet (1.2 m) inside the baseline. While variation is possible in the dimensions of the court and backboard, it is considered important for the basket to be of the correct height; a rim that is off by but a few inches can have an adverse effect on shooting.

There are also regulations on the size a basketball should be. If women are playing, the official basketball size is 28.5" in circumference (size 6) and a weight of 20 oz. For men, the official ball is 29.5" in circumference (size 7) and weighs 22 oz.

Violations

The ball may be advanced toward the basket by being shot, passed between players, thrown, tapped, rolled or dribbled (bouncing the ball while running).

The ball must stay within the court; the last team to touch the ball before it travels out of bounds forfeits possession. The ball-handler may not move both feet without dribbling, known as traveling, nor may he dribble with both hands or catch the ball in between dribbles, a violation called double dribbling. A player's hand cannot be under the ball while dribbling; doing so is known as carrying the ball. A team, once having established ball control in the front half of the court, may not return the ball to the backcourt. The ball may not be kicked nor struck with the fist. A violation of these rules results in loss of possession, or, if committed by the defense, a reset of the shot clock.

There are limits imposed on the time taken before progressing the ball past halfway (8 seconds in international and NBA; 10 seconds in NCAA and high school), before attempting a shot (24 seconds in the NBA, 30 seconds in NCAA women's and Canadian Interuniversity Sport play for both sexes, and 35 seconds in NCAA men's play), holding the ball while closely guarded (5 seconds), and remaining in the restricted area (the lane, or "key") (3 seconds). These rules are designed to promote more offense.

No player may interfere with the basket or ball on its downward flight to the basket, or while it is on the rim (or, in the NBA, while it is directly above the basket), a violation known as goaltending. If a defensive player goaltends, the attempted shot is considered to have been successful. If a teammate of the shooter goaltends, the basket is cancelled and play continues with the defensive team being given possession.

International basketball

The International Basketball Federation was formed in 1932 by eight founding nations: Argentina, Czechoslovakia, Greece, Italy, Latvia, Portugal, Romania and Switzerland. At this time, the organization only oversaw amateur players. Its acronym, derived from the French Fédération Internationale de Basketball Amateur, was thus "FIBA."
Men's Basketball was first included in the Berlin Olympic Games in 1936, although a demonstration tournament was held in 1904. The United States defeated Canada in the first final, played outdoors. This competition has usually been dominated by the United States, whose team has won all but three titles, the first loss in a controversial final game in Munich in 1972 against the Soviet Union. In 1950 the first FIBA World Championship for men was held in Argentina. Three years later, the first FIBA World Championship for Women was held in Chile. Women's basketball was added to the Olympics in 1976, which were held in Montreal, Canada with teams such as the Soviet Union, Brazil and Australia rivaling the American squads.
FIBA dropped the distinction between amateur and professional players in 1989, and in 1992, professional players played for the first time in the Olympic Games. The United States' dominance continued with the introduction of their Dream Team. However, with developing programs elsewhere, other national teams started to beat the United States. A team made entirely of NBA players finished sixth in the 2002 World Championships in Indianapolis, behind Yugoslavia, Argentina, Germany, New Zealand and Spain. In the 2004 Athens Olympics, the United States suffered its first Olympic loss while using professional players, falling to Puerto Rico (in a 19-point loss) and Lithuania in group games, and being eliminated in the semifinals by Argentina. It eventually won the bronze medal defeating Lithuania, finishing behind Argentina and Italy.
Worldwide, basketball tournaments are held for boys and girls of all age levels. The global popularity of the sport is reflected in the nationalities represented in the NBA. Players from all over the globe can be found in NBA teams:
Chicago Bulls star forward Luol Deng is a Sudanese refugee who settled in Great Britain.
Steve Nash, who won the 2005 and 2006 NBA MVP award, is a South Africa-born Canadian.
Andrea Bargnani of the Toronto Raptors, top pick in the 2006 NBA Draft, is from Italy. In addition, American superstar Kobe Bryant spent much of his childhood in Italy while his father was playing there.
Dallas Mavericks superstar and 2007 NBA MVP Dirk Nowitzki is German.
All-Star Pau Gasol of the Los Angeles Lakers is from Spain.
2005 NBA Draft top overall pick Andrew Bogut of the Milwaukee Bucks is Australian. Also, 2008 rookie Nathan Jawai is set to become the first Indigenous Australian ever to play in the league.
Houston Rockets center Yao Ming is from China.
All star and former three point champion Peja Stojakovic is Serbian.
All star Andrei Kirilenko is Russian.
Phoenix Suns guard Leandro Barbosa and Denver Nuggets forward Nenê are Brazilian.
Cleveland Cavaliers big man Žydrūnas Ilgauskas and Linas Kleiza from Denver Nuggets are Lithuanians.
Perhaps no NBA team is as identified by international players as the San Antonio Spurs. The team's three most prominent players are all international—Tim Duncan of the U.S. Virgin Islands, Manu Ginobili of Argentina and Tony Parker of France. (Duncan competes for the United States internationally, as the Virgin Islands did not field a basketball team for international competition until well after Duncan started playing internationally, and all U.S. Virgin Islands natives are United States citizens by birth.)
Ginobili's countryman Andrés Nocioni plays for the Chicago Bulls.
Even in the 90's, many non-American players made their names in the NBA, such as Croats Dražen Petrović and Toni Kukoč, Serb Vlade Divac, Lithuanians Arvydas Sabonis and Šarūnas Marčiulionis and German Detlef Schrempf.
The all-tournament teams at the two most recent FIBA World Championships, held in 2002 in Indianapolis and 2006 in Japan, demonstrate the globalization of the game equally dramatically. Only one member of either team was American, namely Carmelo Anthony in 2006. The 2002 team featured Nowitzki, Ginobili, Yao, Peja Stojakovic of Yugoslavia (now of Serbia), and Pero Cameron of New Zealand. Ginobili also made the 2006 team; the other members were Anthony, Gasol, his Spanish teammate Jorge Garbajosa and Theodoros Papaloukas of Greece. The only players on either team to never have joined the NBA are Cameron and Papaloukas. The strength of international Basketball is evident in the fact that the last three FIBA world championships were won (in order) by Serbia (Yugoslavia in 1998) and Spain.

National Basketball Association

In 1946, the Basketball Association of America (BAA) was formed, organizing the top professional teams and leading to greater popularity of the professional game. The first game was played in Toronto, Ontario, Canada between the Toronto Huskies and New York Knickerbockers on November 1, 1946. Three seasons later, in 1949, the BAA became the National Basketball Association (NBA). An upstart organization, the American Basketball Association, emerged in 1967 and briefly threatened the NBA's dominance until the ABA-NBA merger in 1976. Today the NBA is the top professional basketball league in the world in terms of popularity, salaries, talent, and level of competition.
The NBA has featured many famous players, including George Mikan, the first dominating "big man"; ball-handling wizard Bob Cousy and defensive genius Bill Russell of the Boston Celtics; Wilt Chamberlain, who originally played for the barnstorming Harlem Globetrotters; all-around stars Oscar Robertson and Jerry West; more recent big men Kareem Abdul-Jabbar and Karl Malone; playmaker John Stockton; crowd-pleasing forward Julius Erving; European stars Dirk Nowitzki and Drazen Petrovic and the three players who many credit with ushering the professional game to its highest level of popularity: Larry Bird, Earvin "Magic" Johnson, and Michael Jordan.
The NBA-backed Women's National Basketball Association (WNBA) began in 1997. Though it had an insecure opening season, several marquee players (Sheryl Swoopes, Lisa Leslie and Sue Bird among others) helped the league's popularity and level of competition. Other professional women's basketball leagues in the United States, such as the American Basketball League (1996-1998), have folded in part because of the popularity of the WNBA.
In 2001, the NBA formed a developmental league, the NBDL. As of 2008, the league has sixteen teams.
Basketball teams make up approximately 13 percent of franchised sports in the U.S, and an average of 17,558 spectators regularly attend basketball games in the NBA, with the Chicago Bulls (22,103), Detroit Pistons (22,076) and Cleveland Cavaliers (20,499) topping the popularity stakes. The combined revenue from the 30 NBA teams is approximately $3.37 billion and rising.

U.S. high school basketball

Before widespread school district consolidation, most United States high schools were far smaller than their present day counterparts. During the first decades of the 20th century, basketball quickly became the ideal interscholastic sport due to its modest equipment and personnel requirements. In the days before widespread television coverage of professional and college sports, the popularity of high school basketball was unrivaled in many parts of America. Perhaps the most legendary of high school teams was Indiana's Franklin Wonder Five, which took the nation by storm during the 1920s, dominating Indiana basketball and earning national recognition.
Today virtually every high school in the United States fields a basketball team in varsity competition. Basketball's popularity remains high, both in rural areas where they carry the identification of the entire community, as well as at some larger schools known for their basketball teams where many players go on to participate at higher levels of competition after graduation. In the 2003–04 season, 1,002,797 boys and girls represented their schools in interscholastic basketball competition, according to the National Federation of State High School Associations. The states of Illinois, Indiana and Kentucky are particularly well known for their residents' devotion to high school basketball, commonly called Hoosier Hysteria in Indiana; the critically acclaimed film Hoosiers shows high school basketball's depth of meaning to these rural communities.

College basketball and early leagues

Dr. James Naismith was instrumental in establishing college basketball. He coached at the University of Kansas for six years before handing the reins to renowned coach Forrest "Phog" Allen. Naismith's disciple Amos Alonzo Stagg brought basketball to the University of Chicago, while Adolph Rupp, a student of Naismith's at Kansas, enjoyed great success as coach at the University of Kentucky. In 1892, University of California and Miss Head's School, played the first women's inter-institutional game. Berenson's freshmen played the sophomore class in the first women's collegiate basketball game at Smith College, March 21, 1893. The same year, Mount Holyoke and Sophie Newcomb College (coached by Clara Gregory Baer) women began playing basketball. By 1895, the game had spread to colleges across the country, including Wellesley, Vassar and Bryn Mawr. On February 9, 1895 The first intercollegiate 5-on-5 game was played at Hamline University between Hamline and the School of Agriculture which was affiliated with University of Minnesota.[7][8] The School of Agriculture won in a 9-3 game. The first intercollegiate women's game was on April 4, 1896. Stanford women played Berkeley, 9-on-9, ending in a 2-1 Stanford victory. In 1901, colleges, including the University of Chicago, Columbia University, Dartmouth College, University of Minnesota, the U.S. Naval Academy, the University of Utah and Yale University began sponsoring men's games. By 1910, frequent injuries on the men's courts prompted President Theodore Roosevelt to suggest that college basketball form a governing body, resulting in the creation of the Intercollegiate Athletic Association of the United States (IAAUS). In 1910, that body would change its name to the National Collegiate Athletic Association (NCAA).
The first Canadian interuniversity basketball game was played in Kingston, Ontario in December, 1902, when McGill University visited Queen's University; McGill won 10-6.
Teams abounded throughout the 1920s. There were hundreds of men's professional basketball teams in towns and cities all over the United States and little organization of the professional game. Players jumped from team to team and teams played in armories and smoky dance halls. Leagues came and went. Barnstorming squads such as the Original Celtics and two all African American teams, the New York Renaissance Five ("Rens") and (still in existence as of 2008) the Harlem Globetrotters played up to two hundred games a year on their national tours. Women's basketball was more structured. In 1905, the National Women's Basketball Committee's Executive Committee on Basket Ball Rules was created by the American Physical Education Association. These rules called for six to nine players per team and 11 officials. The International Women's Sports Federation (1924) included a women's basketball competition. 37 women's high school varsity basketball or state tournaments were held by 1925. And in 1926, the Amateur Athletic Union backed the first national women's basketball championship, complete with men's rules. The first women's AAU All-America team was chosen in 1929. Women's industrial leagues sprang up throughout the nation, producing famous athletes like Babe Didrikson of the Golden Cyclones and the All American Red Heads Team who competed against men's teams, using men's rules. By 1938, the women's national championship changed from a three-court game to two-court game with six players per team. The first men's national championship tournament, the National Association of Intercollegiate Basketball tournament, which still exists as the National Association of Intercollegiate Athletics (NAIA) tournament, was organized in 1937. The first national championship for NCAA teams, the National Invitation Tournament (NIT) in New York, was organized in 1938; the NCAA national tournament would begin one year later.
College basketball was rocked by gambling scandals from 1948 to 1951, when dozens of players from top teams were implicated in match fixing and point shaving. Partially spurred by an association with cheating, the NIT lost support to the NCAA tournament.

History of Basketball

In early December 1891, Dr. James Naismith,[2] a Canadian physical education professor from McGill University of Montréal and instructor at YMCA Training School[3] (today, Springfield College) in Springfield, Massachusetts, USA, sought a vigorous indoor game to keep his students occupied and at proper levels of fitness during the long New England winters. After rejecting other ideas as either too rough or poorly suited to walled-in gymnasiums, he wrote the basic rules and nailed a peach basket onto a 10-foot (3.05 m) elevated track. In contrast with modern basketball nets, this peach basket retained its bottom, and balls had to be retrieved manually after each "basket" or point scored; this proved inefficient, however, so a hole was drilled into the bottom of the basket, allowing the balls to be poked out with a long dowel each time. The peach baskets were used until 1906 when they were finally replaced by metal hoops with backboards. A further change was soon made, so the ball merely passed through, paving the way for the game we know today. A soccer ball was used to shoot goals. Whenever a person got the ball in the basket, his team would gain a point. Whichever team got the most points won the game.[4] The baskets were originally nailed to the mezzanine balcony of the playing court, but this proved impractical when spectators on the balcony began to interfere with shots. The backboard was introduced to prevent this interference; it had the additional effect of allowing rebound shots.[5] Naismith's handwritten diaries, discovered by his granddaughter in early 2006, indicate that he was nervous about the new game he had invented, which incorporated rules from a children's game called "Duck on a Rock", as many had failed before it. Naismith called the new game "Basket Ball".[6]
The first official game was played in the YMCA gymnasium on January 20, 1892 with nine players. The game ended at 1-0; the shot was made from 25 feet (7.6 m), on a court just half the size of a present-day Streetball or National Basketball Association (NBA) court. By 1897–1898 teams of five became standard.
Women's basketball began in 1892 at Smith College when Senda Berenson, a physical education teacher, modified Naismith's rules for women. Shortly after she was hired at Smith, she went to Naismith to learn more about the game. Fascinated by the new sport and the values it could teach, she organized the first women’s collegiate basketball game on March 21, 1893, when her Smith freshmen and sophomores played against one another. Her rules were first published in 1899 and two years later Berenson became the editor of A.G. Spalding’s first Women's Basketball Guide, which further spread her version of basketball for women.
Basketball's early adherents were dispatched to YMCAs throughout the United States, and it quickly spread through the USA and Canada. By 1895, it was well established at several women's high schools. While the YMCA was responsible for initially developing and spreading the game, within a decade it discouraged the new sport, as rough play and rowdy crowds began to detract from the YMCA's primary mission. However, other amateur sports clubs, colleges, and professional clubs quickly filled the void. In the years before World War I, the Amateur Athletic Union and the Intercollegiate Athletic Association of the United States (forerunner of the NCAA) vied for control over the rules for the game. The first pro league, the National Basketball League, was formed in 1898 to protect players from exploitation and to promote a less rough game. This league only lasted 5 years.
By the 1950s, basketball had become a major college sport, thus paving the way for a growth of interest in professional basketball. In 1959, a basketball hall of fame was founded in Springfield, Massachusetts. Its rosters include the names of great players, coaches, referees and people who have contributed significantly to the development of the game.
Basketball was originally played with a soccer ball. The first balls made specifically for basketball were brown, and it was only in the late 1950s that Tony Hinkle, searching for a ball that would be more visible to players and spectators alike, introduced the orange ball that is now in common use. Dribbling was not part of the original game except for the "bounce pass" to teammates. Passing the ball was the primary means of ball movement. Dribbling was eventually introduced but limited by the asymmetric shape of early balls. Dribbling only became a major part of the game around the 1950s as manufacturing improved the ball shape.
Basketball, netball, dodgeball, volleyball, and lacrosse are the only ball games which have been identified as being invented by North Americans. Other ball games, such as baseball and Canadian football, have Commonwealth of Nations, European, Asian or African connections. Although there is no direct evidence as yet that the idea of basketball came from the ancient Mesoamerican ballgame, knowledge of that game had been available for at least 50 years prior to Naismith's creation in the writings of John Lloyd Stephens and Alexander von Humboldt. Stephen's works especially, which included drawings by Frederick Catherwood, were available at most educational institutions in the 19th century and also had wide popular circulation.
