Introduction to nba, I want to use

☆ 1896, the first American basketball organization, the National Basketball League (NBL), was established, but at that time, the basketball rules and organization were not perfect. Usually, a player can represent several teams in a season. After several seasons, the organization existed in name only.

☆1On April 6, 946, the American Basketball Association (BAA) was founded by Walter A. Brown, the owner of Boston Garden in the United States. Brown first proposed high salary system and contract system, which became the two cornerstones of modern professional basketball. High salary system means that professional basketball must have strong financial support in order to keep the game at a high level, attract audiences and survive. Contract system means that a player can only sign a contract with one club and set up a player reserve system to prevent players from leaving the team suddenly and causing losses.

☆ 1949, with Brown's efforts, two major American basketball organizations, BAA and NBL, merged into the National Basketball Association (NBA). Brown also became the founder of the later famous Boston Celtics. When the NBA was founded, there were 17 teams, which were divided into three divisions. The Minneapolis Lakers from NBL won the NBA championship in the first season with the help of george mikan, the No.1 center in the United States, who is 2.09 meters tall.

☆ 1952, in order to limit the scoring ability of the first center george mikan, the NBA expanded the width of the 3-second penalty area at the basket from 6 feet to 12 feet. In 1960s, because of the appearance of another super center, Chamberlain, the NBA expanded the width of the penalty area to 16 feet. Because NBA teams often use delaying tactics when the score is ahead, the game can't attract the audience. From the season of 1954- 1955, the NBA began to implement the 24-second system, that is, the offensive time of each team should not exceed 24 seconds.

☆ From the beginning of the 1954-55 season, the NBA was naturally eliminated, leaving only two major divisions, the Eastern Division and the Western Division. Among them, the eastern alliance is divided into Atlantic region and central region; The western alliance is divided into the central and western regions and the Pacific region.

☆ 1967, a new basketball organization ABA (American Basketball Association) was announced, with George Macon as the first chairman. Aba adopts red, white and blue basketball, implements the three-point system of long-distance shooting, and holds a dunk contest every year. These measures are not allowed in the NBA.

☆ 1973, CBS bought the right to broadcast NBA games for three years for $27 million, which made NBA games appear on TV for the first time. However, because there were no conditions for live broadcast at that time, only videos could be played.

☆ 1976 However, due to poor management, Aba was annexed by the American NBA, and the number of teams increased to 22. Since then, NBA has formed a monopoly on American basketball industry.

65438-0979, the NBA began to implement the 3-point long-distance shooting system. In order to avoid the disparity in strength between teams, the NBA has established an annual "NBA rookie selection and distribution system", which ranks college students who graduated in that year according to their level, and then each club selects them in turn according to the final ranking of the league in that year and the final draw. The latter ranks first, and each team can only choose one in each round, thus ensuring that the weakest team can get the highest level rookie, while the weak team who chooses new stars will often be reborn in the new season. In order to prevent rich teams from monopolizing high-paid star players, the NBA has set a total salary limit for each team. If you spend a lot of money to buy a star, you can't buy other excellent players. This system ensures that the best stars are evenly distributed in each team, which makes the strength of each team very close. If "high salary system" and "contract system" are the two cornerstones of NBA, then "rookie selection system" and "salary limit system" ensure the tension and excitement of NBA games, and the unpredictability of the games attracts many American fans to the basketball court. The NBA league also implements the transfer system, and NBA players can't buy or sell, so they can only be replaced by people. From the beginning of the season to 9: 00 pm on Thursday 16, the team can exchange players freely. Since then, all the players have been "frozen" until the end of the regular season. NBA transfer is the exchange of people and contracts.

☆ 1980, Dallas Mavericks joined the NBA.

1988, New Orleans Hornets and Miami Heat joined the NBA.

1990, Orlando Magic and Minnesota Timberwolves joined the NBA.

☆ 1995, two Canadian teams joined the NBA, Toronto Raptors and Vancouver Grizzlies (later renamed Memphis Grizzlies), bringing the number of NBA teams to 29.

☆ In 2004, the Charlotte Bobcats joined 30 teams.

☆ In 2005, the 58th birthday candle was blown out. On the cake is the latest edition of NBA in 2005. Charlotte bobcats became another cherry on butter. Thirty, not the old tree rings with grain precipitation, but a new time and space for memory expansion. From 1946 to 2004, the bar code of the team went from 1 1 to No.30, which was unprecedented in the NBA.

☆ In 2006, American International Group, Google, Oracle Bone Inscriptions, Yahoo, Telstra, Bunny (Internet) Group, British Shell Oil, Three Kingdoms King, Philips, Qilong Bubble and Huaqi Bank became the first-class sponsors of the NBA.
