USA Basketball

USA Basketball (USAB) is a non-profit organization and the governing body for basketball in the United States. The organization represents the United States in FIBA and the men's and women's national basketball teams in the United States Olympic Committee. Its Chairman of the Board is Jerry Colangelo and its executive director is Jim Tooley.

The organization was founded in 1974 as the Amateur Basketball Association of the United States of America (ABAUSA). It was renamed to USA Basketball on October 12, 1989, after FIBA modified its rules to allow professional basketball players to compete in international competitions. USA Basketball is responsible for the selection and training of the men's and women's teams that represent the United States in international tournaments, including the FIBA Basketball World Cup for men, the FIBA Women's Basketball World Cup, Games of the Olympiad and the men's and women's qualifiers therefore, as well as for the promotion of the sport amongst prospective players, spectators, and fans.

World championship

A world championship is generally an international sports competition open to elite competitors from across the world, representing their nations, and winning such an event will be considered the highest or near highest achievement in the sport or contest.

The title is usually awarded through a combination of specific contests or, less commonly, ranking systems (e.g. the ICC Test Championship), or a combination of the two (e.g. World Triathlon Championships in Triathlon). This determines a 'world champion', who or which is commonly considered the best nation, team, individual (or other entity) in the world in a particular field, although the vagaries of sport ensure that the competitor recognised at the best in an event is not always the 'world champion' (see Underdog).

Certain sports do not have a world championship, instead they may organise a world cup competition, or they may organize both. Often, the use of the term cup or championship in this sense is just a choice of words. Some sports have multiple champions because of multiple organizations such as mixed martial arts, boxing and wrestling.

National Basketball Association

The National Basketball Association (NBA) is the pre-eminent men's professional basketball league in North America, and is widely considered to be the premier men's professional basketball league in the world. It has 30 franchised member clubs (29 in the United States and 1 in Canada), and is an active member of USA Basketball (USAB), which is recognized by FIBA (also known as the International Basketball Federation) as the national governing body for basketball in the United States. The NBA is one of the four major North American professional sports leagues. NBA players are the world's best paid sportsmen, by average annual salary per player.

The league was founded in New York City on June 6, 1946, as the Basketball Association of America (BAA). The league adopted the name National Basketball Association on August 3, 1949, after merging with its rival National Basketball League (NBL). The league's several international as well as individual team offices are directed out of its head offices located in the Olympic Tower at 645 Fifth Avenue in New York City. NBA Entertainment and NBA TV studios are directed out of offices located in Secaucus, New Jersey.

Game

A game is structured form of play, usually undertaken for enjoyment and sometimes used as an educational tool. Games are distinct from work, which is usually carried out for remuneration, and from art, which is more often an expression of aesthetic or ideological elements. However, the distinction is not clear-cut, and many games are also considered to be work (such as professional players of spectator sports or games) or art (such as jigsaw puzzles or games involving an artistic layout such as Mahjong, solitaire, or some video games).

Key components of games are goals, rules, challenge, and interaction. Games generally involve mental or physical stimulation, and often both. Many games help develop practical skills, serve as a form of exercise, or otherwise perform an educational, simulational, or psychological role.

Attested as early as 2600 BC, games are a universal part of human experience and present in all cultures. The Royal Game of Ur, Senet, and Mancala are some of the oldest known games.
