In December 1891,Â
James Naismith, a Canadian professor ofÂ
physical education and instructor at the InternationalÂ
Young Mens Christian Association Training School (nowÂ
Springfield College) inÂ
Springfield, Massachusetts,
 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 longÂ
New England winters. After rejecting other ideas as either too rough or poorly suited to walled-inÂ
gymnasiums, he invented a new game in which players would pass a ball to teammates and try to score points by tossing the ball into a basket mounted on a wall. Naismith wrote the basicÂ
rules and nailed aÂ
peach basket onto an elevated track. Naismith initially set up the peach basket with its bottom intact, which meant that the ball had to be retrieved manually after each basket or point scored. This quickly proved tedious, so Naismith removed the bottom of the basket to allow the balls to be poked out with a longÂ
dowel after each scored basket.
Old style basketball with lacesBasketball was originally played with a soccer ball. These round balls from
association football were made, at the time, with a set of laces to close off the hole needed for inserting the inflatable bladder after the other sewn-together segments of the balls cover had been flipped outside-in.
 These laces could cause bounce passes and dribbling to be unpredictable.
 Eventually a lace-free ball construction method was invented, and this change to the game was endorsed by Naismith. (Whereas inÂ
American football, the lace construction proved to be advantageous for gripping and remains to this day.) The first balls made specifically for basketball were brown, and it was only in the late 1950s thatÂ
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 was common by 1896, with a rule against the double dribble by 1898.
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.
 The baskets were originally nailed to the mezzanine balcony of the playing court, but this proved impractical when spectators in the balcony began to interfere with shots. The backboard was introduced to prevent this interference; it had the additional effect of allowing rebound shots.
 Naismiths 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 childrens game calledÂ
duck on a rock, as many had failed before it.Frank Mahan, one of the players from the original first game, approached Naismith after the Christmas break, in early 1892, asking him what he intended to call his new game. Naismith replied that he hadnt thought of it because he had been focused on just getting theÂ
game started. Mahan suggested that it be called Naismith ball, at which he laughed, saying that a name like that would kill any game. Mahan then said, Why not call it basketball? Naismith replied, We have a basket and a ball, and it seems to me that would be a good name for it.
 The first official game was played in theÂ
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-dayÂ
Streetball orÂ
National Basketball Association (NBA) court.At the time,Â
soccer was being played with 10 to a team (which was increased to 11). When winter weather got too icy to play soccer, teams were taken indoors, and it was convenient to have them split in half and play basketball with five on each side. By 1897–1898 teams of five became standard.College basketball

By 1895, it was well established at several womens high schools. While 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 YMCAs primary mission. However, other amateur sports clubs, colleges, and professional clubs quickly filled the void. In the years before World War I, theÂ
Amateur Athletic Union and theÂ
Intercollegiate Athletic Association of the United States (forerunner of theÂ
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.James Naismith was instrumental in establishingÂ
college basketball. His colleague C.O. Beamis fielded the first college basketball team just a year after the Springfield YMCA game at the suburbanÂ
PittsburghÂ
Geneva College.
 Naismith himself later coached at theÂ
University of Kansas for six years, before handing the reins to renowned coachÂ
Forrest Phog Allen. Naismiths discipleÂ
Amos Alonzo Stagg brought basketball to theÂ
University of Chicago, whileÂ
Adolph Rupp, a student of Naismiths at Kansas, enjoyed great success as coach at theÂ
University of Kentucky. On February 9, 1895, the first intercollegiate 5-on-5 game was played atÂ
Hamline University between Hamline and the School of Agriculture, which was affiliated with theÂ
University of Minnesota.
 The School of Agriculture won in a 9–3 game.In 1901, colleges, including theÂ
University of Chicago,Â
Columbia University,Â
Cornell University,Â
Dartmouth College, theÂ
University of Minnesota, theÂ
U.S. Naval Academy, theÂ
University of Colorado andÂ
Yale University began sponsoring mens games. In 1905, frequent injuries on theÂ
football field promptedÂ
PresidentÂ
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 changed its name to theÂ
National Collegiate Athletic Association (NCAA). The first Canadian interuniversity basketball game was played atÂ
YMCAÂ inÂ
Kingston, Ontario on February 6, 1904, whenÂ
McGill University – Naismiths alma mater – visitedÂ
Queens 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.
The first mens national championship tournament, the National Association of Intercollegiate Basketball tournament, which still exists as theÂ
National Association of Intercollegiate Athletics (NAIA)Â
tournament, was organized in 1937. The first national championship for NCAA teams, theÂ
National Invitation Tournament (NIT) in New York, was organized in 1938; theÂ
NCAA national tournament began one year later. College basketball was rocked by gambling scandals from 1948 toÂ
1951, when dozens of players from top teams were implicated inÂ
match fixing andÂ
point shaving. Partially spurred by an association with cheating, the NIT lost support to the NCAA tournament.High school basketballSee also:Â

A basketball game between the Heart Mountain and Powell High School girls teams, Wyoming, March 1944Before widespreadÂ
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 IndianasÂ
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 inÂ
varsity competition.
 Basketballs 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 2016–17 season, 980,673 boys and girls represented their schools in interscholastic basketball competition, according to theÂ
National Federation of State High School Associations.
 The states ofÂ
Illinois,Â
Indiana andÂ
Kentucky are particularly well known for their residents devotion to high school basketball, commonly calledÂ
Hoosier Hysteria in Indiana; the critically acclaimed filmÂ
Hoosiers shows high school basketballs depth of meaning to these communities.There is currently no tournament to determine a national high school champion. The most serious effort was the National Interscholastic Basketball Tournament at theÂ
University of Chicago from 1917 to 1930. The event was organized byÂ
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 theÂ
National Federation of State High School Associations andÂ
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.
 The tournament did not invite minority schools or private/parochial schools.The National Catholic Interscholastic Basketball Tournament ran from 1924 to 1941 atÂ
Loyola University.
 The National Catholic Invitational Basketball Tournament from 1954 to 1978 played at a series of venues, includingÂ
Catholic University,Â
Georgetown andÂ
George Mason.
 The National Interscholastic Basketball Tournament for Black High Schools was held from 1929 to 1942 atÂ
Hampton Institute.
 The National Invitational Interscholastic Basketball Tournament was held from 1941 to 1967 starting out atÂ
Tuskegee Institute. Following a pause duringÂ
World War IIÂ it resumed atÂ
Tennessee State College in Nashville. The basis for the champion dwindled after 1954 whenÂ
Brown v. Board of Education began an integration of schools. The last tournaments were held atÂ
Alabama State College from 1964 to 1967.
Professional basketball
Ad from The Liberator magazine promoting an exhibition in Harlem, March 1922. Drawing byÂ
Hugo Gellert.Teams abounded throughout the 1920s. There were hundreds of mensÂ
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.Â
Barnstorming squads such as theÂ
Original Celtics and two all-African American teams, theÂ
New York Renaissance Five (Rens) and the (still existing)Â
Harlem Globetrotters played up to two hundred games a year on their national tours.In 1946, theÂ
Basketball Association of America (BAA) was formed. The first game was played inÂ
Toronto, Ontario, Canada between theÂ
Toronto Huskies andÂ
New York Knickerbockers on November 1, 1946. Three seasons later, in 1949, the BAA merged with theÂ
National Basketball League (NBL) to form theÂ
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, aÂ
basketball hall of fame was founded inÂ
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, theÂ
American Basketball Association, emerged in 1967 and briefly threatened the NBAs dominance until theÂ
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, includingÂ

In 2001, the NBA formed a developmental league, the National Basketball Development League (later known as the NBA D-League and then theÂ
NBA G League after a branding deal withÂ
Gatorade). As of the 2018–19 season, the G League has 27 teams.International basketball
The U.S. playing against Mexico at the 2014 FIBA World CupFIBA (International Basketball Federation) was formed in 1932 by eight founding nations:Â
Argentina,Â
Czechoslovakia,Â
Greece,Â
Italy,Â
Latvia,Â
Portugal,Â
Romania andÂ
Switzerland. At this time, the organization only oversaw amateur players. Its acronym, derived from the FrenchÂ
Fédération Internationale de Basket-ball Amateur, was thus FIBA. Mens basketball was firstÂ
included at the BerlinÂ
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 of these came in a controversial final game inÂ
Munich inÂ
1972Â against the Soviet Union, in which the ending of the game was replayed three times until the Soviet Union finally came out on top.
 In 1950 the first FIBA World Championship for men, now known as theÂ
FIBA Basketball World Cup, was held in Argentina. Three years later, the first FIBA World Championship for women, now known as theÂ
FIBA Womens Basketball World Cup, was held in Chile. Womens basketball was added to the Olympics in 1976, which were held inÂ
Montreal, Quebec, Canada with teams such as theÂ
Soviet Union,Â
Brazil andÂ
Australia rivaling theÂ
American squads.In 1989,Â
FIBAÂ allowed professional NBA players to participate in the Olympics for the first time. Prior to theÂ
1992 Summer Olympics, only European and South American teams were allowed to field professionals in the Olympics. The United States dominance continued with the introduction of the originalÂ
Dream Team. In theÂ
2004 Athens Olympics, the United States suffered its first Olympic loss while using professional players, falling toÂ
Puerto Rico (in a 19-point loss) andÂ
Lithuania in group games, and being eliminated in the semifinals byÂ
Argentina. It eventually won the bronze medal defeating Lithuania, finishing behind Argentina andÂ
Italy. TheÂ
Redeem Team, won gold at theÂ
2008 Olympics, and the B-Team, won gold at theÂ
2010 FIBA World Championship in Turkey despite featuring no players from the 2008 squad. The United States continued its dominance as they won gold at theÂ
2012 Olympics,Â
2014 FIBA World Cup and theÂ
2016 Olympics.

Philippine Basketball Associations first game was played on April 9, 1975, at theÂ
Araneta Coliseum inÂ
Cubao,Â
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 leagues first season that opened on April 9, 1975. TheÂ
NBLÂ is Australias pre-eminent mens professional basketball league. The league commenced inÂ
1979, playing a winter season (April–September) and did so until the completion of the 20th season inÂ
1998. TheÂ
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 againstÂ
Australias various football codes. It features 8 teams from around Australia and one in New Zealand. A few players includingÂ
Luc Longley,Â
Andrew Gaze,Â
Shane Heal,Â
Chris Anstey andÂ
Andrew Bogut made it big internationally, becoming poster figures for the sport in Australia. TheÂ
Womens National Basketball League began in 1981.Womens basketballSee also:Â

The Australian womens basketball team on winning theÂ
2006 FIBA World ChampionshipWomens basketball began in 1892 atÂ
Smith College whenÂ
Senda Berenson, a physical education teacher, modified Naismiths 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 womens collegiate basketball game on March 21, 1893, when her Smith freshmen and sophomores played against one another.
 However, the first womens interinstitutional game was played in 1892 between theÂ
University of California and Miss Heads School.
 Berensons rules were first published in 1899, and two years later she became the editor ofÂ
A. G. Spaldings first Womens Basketball Guide.
 Berensons freshmen played the sophomore class in the first womens intercollegiate basketball game atÂ
Smith College, March 21, 1893.
 The same year,Â
Mount Holyoke andÂ
Sophie Newcomb College (coached byÂ
Clara Gregory Baer) women began playing basketball. By 1895, the game had spread to colleges across the country, includingÂ
Wellesley,Â
Vassar, andÂ
Bryn Mawr. The first intercollegiate womens game was on April 4, 1896.Â
Stanford women playedÂ
Berkeley, 9-on-9, ending in a 2–1 Stanford victory.Womens basketball development was more structured than that for men in the early years. In 1905, the Executive Committee on Basket Ball Rules (National Womens Basketball Committee) was created by theÂ
American Physical Education Association.
 These rules called for six to nine players per team and 11 officials. TheÂ
International Womens Sports Federation (1924) included a womens basketball competition. 37 womens high school varsity basketball or state tournaments were held by 1925. And in 1926, the Amateur Athletic Union backed the firstÂ
national womens basketball championship, complete with mens rules.
 TheÂ
Edmonton Grads, a touring Canadian womens team based inÂ
Edmonton, Alberta, operated between 1915 and 1940. The Grads toured all over NorthÂ
America, and were exceptionally successful. They posted a record of 522 wins and only 20 losses over that span, as they met any team that wanted to challenge them, funding their tours from gate receipts.
 The Grads also shone on several exhibition trips to Europe, and won four consecutive exhibition Olympics tournaments, in 1924, 1928, 1932, and 1936; however, womens 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 womensÂ
AAUÂ All-America team was chosen in 1929.
 Womens industrial leagues sprang up throughout the United States, producing famous athletes, includingÂ
Babe Didrikson of theÂ
Golden Cyclones, and theÂ
All American Red Heads Team, which competed against mens teams, using mens rules. By 1938, the womens national championship changed from a three-court game toÂ
two-court game with six players per team.
Brittney Griner accepting an awardThe NBA-backedÂ
Womens National Basketball Association (WNBA) began in 1997. Though it had shaky attendance figures, several marquee players (
Lisa Leslie,Â
Diana Taurasi, andÂ
Candace Parker among others) have helped the leagues popularity and level of competition. OtherÂ
professional womens basketball leagues in the United States, such as theÂ
American Basketball League (1996–98), 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 withÂ
ESPN. The new television deal ran from 2009 to 2016. Along with this deal, came the first-ever rights fees to be paid to a womens professional sports league. Over the eight years of the contract, millions and millions of dollars were dispersed to the leagues teams. In a March 12, 2009 article,Â
NBAÂ commissionerÂ
David Stern said that in the bad economy, the NBA is far less profitable than the WNBA. Were losing a lot of money among a large number of teams. Were budgeting the WNBA to break even this year.
