1. Basketball

2. Basketball is a team sport in which two teams of five players try to score points by throwing or "shooting" a ball through the top of a basketball hoop while following a set of rules. Basketball is one of the world's most popular and widely viewed sports. A regulation basketball hoop consists of a rim 18 inches in diameter and 10 feet high mounted to a backboard. A team can score a field goal by shooting the ball through the hoop during regular play. A field goal scores two points for the shooting team if a player is touching or closer to the hoop than the three-point line, and three points (a "3 pointer") if the player is "outside" the three-point line. The team with more points at the end of the game wins, but additional time (overtime) may be issued when the game ends with a tie. The ball can be advanced on the court by bouncing it while walking or running (dribbling) or passing it to a teammate. It is a violation (traveling) to walk with the ball, carry it, or to double dribble (to hold the ball and then resume dribbling). Various violations are generally called "fouls". Disruptive physical contact (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. Basketball has evolved many commonly used techniques of shooting, passing, and dribbling, as well as specialized player positions and offensive and defensive structures (player positioning) and techniques. Typically, the tallest members of a team will play "center", "small forward", or "power forward" positions, while shorter players or those who possess the best ball handling skills and speed play "point guard" or "shooting guard". While competitive basketball is carefully regulated, numerous variations of basketball have developed for casual play. Competitive basketball is primarily an indoor sport played on carefully marked and maintained basketball courts, but less regulated variations are often played outdoors in both inner city and rural areas.

3. Professional Basketball Teams abounded throughout the 1920s
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 (still in existence as of 2010) the 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, Three seasons later, in 1949, the BAA merged with the National Basketball League to 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 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 2008, the league has 16 teams.

4. 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 metres (20 ft 6 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)or 12 minutes (NBA).College games use two 20-minute halves,while high school varsity games use 8 minute quarters.[15 minutes are allowed for a half-time break under FIBA, NBA, and NCAA rules and 10 minutes in high school. Overtime periods are five minutes in length. except for high school which is four minutes in length.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.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.

5. History of Basketball
James Naismith was the Canadian physical education instructor who invented basketball in James Naismith was born in Almonte, Ontario and educated at McGill University and Presbyterian College in Montreal. He was the physical education teacher at McGill University (1887 to 1890) and at Springfield College in Springfield, Massachusetts (1890 to 1895). At Springfield College (which was then the Y.M.C.A. training school), James Naismith, under the direction of American phys-ed specialist Luther Halsey Gulick, invented the indoor sport of basketball.

6. Basic Skills in Basketball
Shooting
is an attempt to score a basket by jumping, usually straight up, and in mid-jump, propelling the ball in an arc into the basket. It is accomplished by the player bringing his or her elbow up until it is aligned with the hoop, then sent towards the hoop in a high arc. It is considered the easiest shot to make from a distance. The purposes of the jump are to make it more difficult for the defender to block, and to put more power behind the shot. It is also usually accomplished with one hand by the NBA players. It is the most effective in open play but can prove to be hard when there is a taller player in front of you

7. Dribbling
a dribble is one of the most difficult ball skills to master and one of the most useful attacking moves. In typical game play, players attempt to propel the ball toward their opponents' goal through individual control of the ball, such as by dribbling (running with the ball close to their feet). Dribbling is often invaluable especially in the third part of a pitch or at the wings, where most attacks take place. Dribbling creates space in tight situations where the dribbler is marked (closely guarded by a defender), and the dribbler can either score or create scoring chances after a successful dribble. However, dribbling, if poorly mastered and used, may result in the loss of possession either when the ball is intercepted or tackled by a defender.

8. Blocking
a block (short for blocked shot), not to be confused with blocking, occurs when a defensive player legally deflects a field goal attempt from an offensive player. The defender must not touch the offensive player's hands or otherwise a foul is called. In order to be legal, the block must occur while the shot is traveling upward or at its apex. If it is heading downward when the defender hits it, it is ruled as goaltending and counts as a made basket. Goaltending is also called if the block is made after the ball bounces on the backboard (NFHS excepted; the NCAA also used this rule until the 2009–10 season). Nicknames for blocked shots include "rejections," "stuffs," "facials," "swats," "denials," and "packs." Blocked shots were first officially recorded in the NBA during the season.

9. Passing
Basketball passing is an integral aspect of a good offensive attack. As we mention at other places on our site, everyone wants to be good at basketball shooting. But how do you get the best shots? By having a greatbasketball passing attack. Passers must deliver accurate, crisp passes. They must always be on thelook-out for the open teammate. Receivers must keep their eyes on the ball at all times and always consider themselves a potential receiver.
