Basketball is a sport played by two teams of five players on a rectangular court. The objective is to shoot a ball through a hoop 18 inches (46 cm) in diameter and 10 feet (3.0 m) high mounted to a backboard at each end. Basketball is one of the world's most popular and widely viewed sports.[1]
A team can score a field goal by shooting the ball through the basket during regular play. A field goal scores two points for the shooting team if a player is touching or closer to the basket than the three-point line, and three points (known commonly as a 3 pointer or three) if the player is behind the three-point line. The team with the most points at the end of the game wins, but additional time (overtime) may be issued when the game ends with a draw. The ball can be advanced on the court by bouncing it while walking or running or throwing it to a team mate. It is a violation to move without dribbling the ball, to carry it, or to hold the ball with both hands then resume dribbling.
Violations are called "fouls". A personal foul is penalized, and a free throw is usually awarded to an offensive player if he is fouled while shooting the ball. A technical foul may also be issued when certain infractions occur, most commonly for unsportsmanlike conduct on the part of a player or coach. A technical foul gives the opposing team a free throw, and the opposing team also retains possession of the ball.
As well as many techniques for shooting, passing, dribbling and rebounding, basketball has specialized player positions and offensive and defensive structures (player positioning). Typically, the tallest members of a team will play "center", "power forward" or "small forward" positions, while shorter players or those who possess the best ball handling skills and speed play "point guard" or "shooting guard".
History
Main article: History of basketball
Creation
In early December 1891, Canadian American Dr. James Naismith,[2] a physical education professor and instructor at the International Young Men's Christian Association Training School[3] (YMCA) (today, Springfield College) in Springfield, Massachusetts, USA), was trying to keep his gym class active on a rainy day. He sought a vigorous indoor game to keep his students occupied and at proper levels of fitness during the longNew 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 the bottom of the basket was removed,[4]allowing the balls to be poked out with a long dowel each time.
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.
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. Whenever a person got the ball in the basket, his team would gain a point. Whichever team got the most points won the game.[5] 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.[6] 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".[7] The first official game was played in the YMCA gymnasium in Albany, New York 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.
College basketball
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 five years.
Dr. James Naismith was instrumental in establishing college basketball. His colleague C.O. Beamis fielded the first college basketball team just a year after the Springfield YMCA game at the suburban Pittsburgh Geneva College.[8] Naismith himself later coached at theUniversity 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. 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 the University of Minnesota.[9][10] The School of Agriculture won in a 9–3 game.
In 1901, colleges, including the University of Chicago, Columbia University, Dartmouth College, the University of Minnesota, the U.S. Naval Academy, the University of Colorado andYale University began sponsoring men's games. In 1905, frequent injuries on the football field prompted President Theodore Roosevelt to suggest that colleges 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 at the YMCA in Kingston, Ontario on February 6, 1904, when McGill University visited Queen's University. McGill won 9–7 in overtime; the score was 7–7 at the end of regulation play, and a ten-minute overtime period settled the outcome. A good turnout of spectators watched the game.[11]
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.
High school basketball
 | The examples and perspective in this article deal primarily with the United States and do not represent a worldwide viewof the subject. (August 2012) |
Before widespread school district consolidation, most American 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.[12] 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 communities.
There is currently no national tournament to determine a national high school champion. The most serious effort was the National Interscholastic Basketball Tournament at the University of Chicago from 1917 to 1930. The event was organized by Amos Alonzo Stagg and sent invitations to state champion teams. The tournament started out as a mostly Midwest affair but grew. In 1929 it had 29 state champions. Faced with opposition from the National Federation of State High School Associations and North Central Association of Colleges and Schools that bore a threat of the schools losing their accreditation the last tournament was in 1930. The organizations said they were concerned that the tournament was being used to recruit professional players from the prep ranks.[13] The tournament did not invite minority schools or private/parochial schools.
The National Catholic Interscholastic Basketball Tournament ran from 1924 to 1941 at Loyola University.[14] The National Catholic Invitational Basketball Tournament from 1954 to 1978 played at a series of venues, including Catholic University, Georgetown and George Mason.[15] The National Interscholastic Basketball Tournament for Black High Schools was held from 1929 to 1942 at Hampton Institute.[16] The National Invitational Interscholastic Basketball Tournament was held from 1941 to 1967 starting out at Tuskegee Institute. Following a pause during World War II it resumed at Tennessee State College in Nashville. The basis for the champion dwindled after 1954 when Brown v. Board of Education began an integration of schools. The last tournaments were held at Alabama State College from 1964 to 1967.[17]
Professional basketball
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 the (still existing) Harlem Globetrotters played up to two hundred games a year on their national tours.
In 1946, the Basketball Association of America (BAA) was formed. 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 merged with the National Basketball Leagueto form the National Basketball Association (NBA). 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, site of the first game. Its rosters include the names of great players, coaches, referees and people who have contributed significantly to the development of the game. The hall of fame has people who have accomplished many goals in their career in basketball. 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, Shaquille O'Neal and Karl Malone; playmaker John Stockton; crowd-pleasing forward Julius Erving; European stars Dirk Nowitzki and Dražen Petrović 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. In 2001, the NBA formed a developmental league, the NBDL. As of 2012, the league has 16 teams.
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 at the Berlin 1936 Summer Olympics, 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 1972against 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. In 2006, in the World Championship of Japan, the United States advanced to the semifinals but were defeated by Greece by 101–95. In the bronze medal game it beat team Argentina and finished 3rd behind Greece and Spain. After the disappointments of 2002 through 2006, the U.S. regrouped, reestablishing themselves as the dominant international team behind the "Redeem Team", which won gold at the 2008 Olympics, and the so-called "B-Team", which won gold at the2010 FIBA World Championship in Turkey despite featuring no players from the 2008 squad.
The all-tournament teams at the 2002 and 2006 FIBA World Championships, respectively held in Indianapolis and 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 all-tournament team from the 2010 edition in Turkey featured four NBA players—MVP Kevin Durant of Team USA and the Oklahoma City Thunder, Linas Kleiza of Lithuania and the Toronto Raptors, Luis Scola of Argentina and theHouston Rockets, and Hedo Türkoğlu of Turkey and the Phoenix Suns. The only non-NBA player was Serbia's Miloš Teodosić. The strength of international Basketball is evident in the fact that Team USA won none of the three world championships held between 1998 and 2006, with Serbia (then known as Yugoslavia) winning in 1998 and 2002 and Spain in 2006.
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 six inhabited continents currently play in the NBA. Top international players began coming into the NBA in the mid-1990s, including Croatians Dražen Petrović and Toni Kukoč, Serbian Vlade Divac, Lithuanians Arvydas Sabonis and Šarūnas Marčiulionis and German Detlef Schrempf.
In the Philippines, the Philippine Basketball Association's first game was played on April 9, 1975 at the Araneta Coliseum in Cubao, Quezon City. Philippines. It was founded as a "rebellion" of several teams from the now-defunct Manila Industrial and Commercial Athletic Association which was tightly controlled by the Basketball Association of the Philippines (now defunct), the then-FIBA recognized national association. Nine teams from the MICAA participated in the league's first season that opened on April 9, 1975. TheNBL is Australia's pre-eminent men's professional basketball league. The league commenced in 1979, playing a winter season (April–September) and did so until the completion of the 20th season in 1998. The 1998/99 season, which commenced only months later, was the first season after the shift to the current summer season format (October–April). This shift was an attempt to avoid competing directly against Australia's various football codes. It features 8 teams from around Australia and one in New Zealand. A few players including Luc Longley, Andrew Gaze, Shane Heal, Chris Anstey and Andrew Bogut made it big internationally, becoming poster figures for the sport in Australia. The Women's National Basketball League began in 1981.
Women's basketball
In 1891, the University of California and Miss Head's School played the first women's interinstitutional game. 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.[18] 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.[19] 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.[19] Berenson's freshmen played the sophomore class in the first women's intercollegiate basketball game atSmith College, March 21, 1893.[20] 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. 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.
Women's basketball development was more structured than that for men in the early years. In 1905, the Executive Committee on Basket Ball Rules (National Women's Basketball Committee) was created by the American Physical Education Association.[21] 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.[21] The Edmonton Grads, a touring Canadian women's team based in Edmonton, Alberta, operated between 1915 and 1940. The Grads toured all over North America, and were exceptionally successful. They posted a record of 522 wins and only 20 losses over that span, as they met any team which wanted to challenge them, funding their tours from gate receipts.[22] The Grads also shone on several exhibition trips to Europe, and won four consecutive exhibition Olympics tournaments, in 1924, 1928, 1932, and 1936; however, women's basketball was not an official Olympic sport until 1976. The Grads' players were unpaid, and had to remain single. The Grads' style focused on team play, without overly emphasizing skills of individual players. The first women's AAU All-America team was chosen in 1929.[21] Women's industrial leagues sprang up throughout the United States, producing famous athletes, including Babe Didrikson of the Golden Cyclones, and the All American Red Heads Team, which 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.[21]
The NBA-backed Women's National Basketball Association (WNBA) began in 1997. Though it had shaky attendance figures, several marquee players (Lisa Leslie, Diana Taurasi, and Candace Parker among others) have helped the league's popularity and level of competition. Other professional women's basketball leagues in the United States, such as theAmerican Basketball League (1996-1998), have folded in part because of the popularity of the WNBA. The WNBA has been looked at by many as a niche league. However, the league has recently taken steps forward. In June 2007, the WNBA signed a contract extension with ESPN. The new television deal runs from 2009 to 2016. Along with this deal, came the first ever rights fees to be paid to a women's professional sports league. Over the eight years of the contract, "millions and millions of dollars" will be "dispersed to the league's teams." The WNBA gets more viewers on national television broadcasts (413,000) than both Major League Soccer (253,000)[23] and the NHL (310,732).[24] In a March 12, 2009 article, NBA commissioner David Stern said that in the bad economy, "the NBA is far less profitable than the WNBA. We're losing a lot of money amongst a large number of teams. We're budgeting the WNBA to break even this year."[25]
Rules and regulations
Main article: Rules of basketball
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 6.75 metres (22 ft 2 in) from the basket in international games and 23 feet 9 inches (7.24 m) in NBA games. A one-point shot can be earned when shooting from the foul line after a foul is made.
Playing regulations
Games are played in four quarters of 10 (FIBA)[26] or 12 minutes (NBA).[27] College games use two 20-minute halves,[28] while United States high school varsity games use 8 minute quarters.[29] 15 minutes are allowed for a half-time break under FIBA, NBA, and NCAA rules[28][30][31] and 10 minutes in United States high schools.[29] Overtime periods are five minutes in length[28][32][33] except for high school which is four minutes in length.[29] 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 may be on the court at one time.[34][35][36][37] 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 (or sometimes mandated in the NBA) for a short meeting with the players, are allowed. They generally last no longer than one minute (100 seconds in the NBA) unless, for televised games, a commercial break is needed.
The game is controlled by the officials consisting of the referee (referred to as crew chief in the NBA), one or two umpires (referred to as referees in 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
The only essential equipment in a basketball game is the ball and the court: a flat, rectangular surface with baskets at opposite ends. Competitive levels require the use of more equipment such as clocks, score sheets, scoreboard(s), alternating possession arrows, and whistle-operated stop-clock systems.
A regulation basketball court in international games is 91.9 feet long and 49.2 feet wide. In the NBA and NCAA the court is 94 feet by 50 feet. Most courts have wood flooring, usually constructed from maple planks running in the same direction as the longer court dimension.[38] The name and logo of the home team is usually painted on or around the center circle.
The basket is a steel rim 18 inches diameter with an attached net affixed to a backboard that measures 6 feet by 3.5 feet and one basket is at each end of the court. The white outlined box on the backboard is 18 inches high and 2 feet wide. At almost all levels of competition, the top of the rim is exactly 10 feet above the court and 4 feet 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 just a few inches can have an adverse effect on shooting.
The size of the basketball is also regulated. For men, the official ball is 29.5 inches in circumference (size 7, or a "295 ball") and weighs 22 oz. If women are playing, the official basketball size is 28.5 inches in circumference (size 6, or a "285 ball") with a weight of 20 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 is out of bounds if it touches or crosses over a boundary line, or touches a player who is out of bounds. This is in contrast to other sports such asfootball, volleyball, and tennis (but not rugby or American football) where the ball (or player) is still considered in if any part of it is touching a boundary line.
The ball-handler may not step with both feet without dribbling, an infraction known as traveling, nor dribble with both hands or hold the ball and resume dribbling, a violation called double dribbling. Any part of the player's hand cannot be directly 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 their court, may not return the ball to the backcourt and be the first to touch it. The ball may not be kicked, nor be 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 (with some exceptions in the NBA).
There are limits imposed on the time taken before progressing the ball past halfway (8 seconds in FIBA and the NBA; 10 seconds in NCAA men's play and high school for both sexes, but no limit in NCAA women's play), before attempting a shot (24 seconds in FIBA and 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 known as the free-throw lane, (or the "key") (3 seconds). These rules are designed to promote more offense.
No player may touch the ball on its downward trajectory to the basket, unless it is obvious that the ball has no chance of entering the basket (goaltending). In addition, no player may touch the ball while it is on or in the basket; when any part of the ball is in the spacious cylinder above the basket (the area extended upwards from the basket); or when the ball is outside the cylinder, if the player reaches through the basket and touches it. This violation is known as "basket interference". If a defensive player goaltends or commits basket interference, the basket is awarded and the offending team gets the ball. If a teammate of the player shooting goaltends or commits interference, the basket is cancelled and play continues with the defensive team being given possession.
