in Springfield College, Massachusetts, Dr. James Naishmis, an American, created basketball with two broken baskets and a substitute football in 1891 in order to find a way for students to exercise in winter, which led to the NBA in full swing today. When the NBA was born on June 6, 1946, it had a strange name BAA.

the emergence and development of p>NBA is the accumulation and precipitation of basketball in the first 5 years. Since basketball was invented by Dr. James Naishmi in 1891, in 1898, a team in Trenton, New Jersey, USA rented a local auditorium for 25 dollars to play and sold tickets to the audience. In the dividend after the game, captain Cooper made great contributions to organizing the game and first received $1. This "paid basketball game" was recognized as the first "professional basketball game" by Encyclopedia Britannica, and Cooper became the first "professional player" to get income from basketball games. The real contribution of this game lies in discovering and realizing the market value of basketball. There is a relationship between investment and income in the $25. At that time, it was impossible to investigate the number of players from both sides in the auditorium. If each team has at least 5 players (this is the minimum number of players on one side of the competition), then both sides have 1 players and each player gets $15. The total income is $15, plus captain Cooper's $1 bonus, and the investment of $25 brings in $151. After 1996, $151 has grown to more than $4 billion. The basic concepts and principles used by NBA are the same as Cooper's idea of renting an auditorium. After Trenton, the "paid competition" was rapidly launched in the United States. In order to protect the interests of players who take part in "paid competitions", in 1898, teams from all over the country established the first professional basketball organization-"National League" (NBL). Because the economic strength and technical level of each team are far from each other, and there is no mature market operation experience and rules, NBL exists in name only after three or four seasons, and its competitive technical level and management level are very low. After the establishment of NBL, many similar professional basketball organizations appeared in the United States, but all of them were like passing clouds and dying. In 193s, NBL was revived in some small and medium-sized cities, and some small-scale leagues were held. However, due to the lack of sufficient funds to promote sales, the influence of basketball has never been formed.

In p>1945, just after the Second World War, the victorious United States was only immersed in a carnival. A group of shrewd businessmen made a fortune in World War II, and the long-lost sports agents saw this clearly. They contacted the owners of 11 teams and initiated the establishment of BAA. BAA is the predecessor of the NBA. The real birthday of the NBA should be June 6, 1946. On this day, in the Captain's Hotel near grand central terminal, Baa (Basketball Association of America), Adam and Eve of the National Basketball Association, held an inaugural meeting. The meeting decided that 11 teams and each team would play 6 regular games. When BAA was founded, the eleven teams were new york Knicks, Boston Celtics, Chicago Bucks, Cleveland Rebels, Detroit Falcons, Philadelphia Warriors, Sizburg Ironman, Providence Steam Engine, St Louis Bombing Team, Toronto Eskimos and Washington Congress Team. Fifty years later, only the Philadelphia Warriors (now the Golden State Warriors) are left in these teams, while the Boston Celtics and the new york Knicks are still playing in the NBA.

BAA was founded by the owners of eleven ice hockey gymnasiums and gymnasiums. The original intention was to keep the gymnasiums from being idle when they were not playing ice hockey. The owners of these gymnasiums are experts in running gymnasiums. In view of the fact that NBA "National Basketball League" teams are mostly concentrated in some middle and small cities in the central and western regions, they put forward the concept of establishing local famous teams and a nationwide basketball organization in the big cities at that time. Therefore, BAA and other basketball leagues, big and small at that time, had three distinct characteristics: first, all the bosses of eleven teams had their own gymnasiums, so that the teams had their own business territories; Secondly, BAA's players are all basketball players who have just graduated from college, because the university amateur league with home and away system was very successful at that time; Thirdly, BAA league draws lessons from the schedule arrangement of ice hockey league at that time, and divides the team into two leagues, the east and the west, and then divides it into several divisions according to geographical location. In the regular season, teams in each league will play two home and away games, and teams in another league will play one home and away game. Finally, according to the good or bad results, the ranking of entering the playoffs is queued, and only when entering the playoffs can we hope to win the championship. BAA adopts four ***48-minute system, with man-to-man defense and no joint defense. Up to now, these are still the most basic characteristics that distinguish NBA from amateur basketball.

Walter Abram, one of the founders of p>BAA and the owner of Boston Garden Gymnasium, also put forward a new concept of professional basketball, that is, professional basketball must have strong financial support, a player can only play for one club and sign a strict contract, and a player reserve system should be established in the league. These theoretical contributions lie in the introduction of huge funds and legal restrictions into basketball, which laid the two cornerstones of high salary system and contract system for the future development of NBA.

in p>1949, with the annexation of NBL by BAA, in order to avoid possible legal troubles, it was officially renamed as NATIONAL BASKETBALL ASSOCIATION, that is, NBA.

NBA in the p>5s

In the 1949-195 season, after BAA annexed NBL and "unified the six countries", it started a new season with 17 teams, and officially changed its name to NBA-- NATIONALBASKETBALL ASSOCIATION. In 1952, when the road was blocked, the NBA released the 24-second system, which greatly improved the appreciation and scoring rate of the game.

when BAA entered its first season, a star named Joe fulks appeared. Fulks is 1.69 meters tall and comes from the University of Kentucky. At that time, in an era when it was difficult to score more than 8 points in a game, Fulks made outstanding achievements. He was the only player who scored more than 17 points per game in the season, with an average score of 23.2 points per game. Despite Fulks' outstanding performance, he still lacks a national star. Moreover, BAA has also encountered a series of troubles. At the beginning of the second season, there were only seven teams left in BAA. Although a new team was formed in Baltimore to join BAA, making BAA reach eight teams, no one can say for sure whether this professional basketball league can survive in the United States centered on college basketball. Secondly, six of the eight teams are from the east, and they practice regional protectionism and are not very friendly to teams from other regions.

BAA suffered heavy losses in the first two seasons. Not only lost four teams, but also the size of the league dropped sharply from 6 games to 48 games, and the ticket revenue decreased accordingly. The reduction of the game also affected the expansion of new teams in the league. In a dilemma, BAA President PuDollof decided to implement his first plan of annexing NBL, and poached NBL star George McCann. Because this giant with a height of 2.8 meters was the "cash cow" of the basketball court at that time. George McCann was famous in college, but he chose NBL when he graduated from college in 1946. In order to get this key figure, Pu Dollof resisted the pressure of "aristocrats" in BAA, and decided to accept all teams, rich or poor, big or small, as long as they were willing to join BAA, in order to lure the Minneapolis Lakers who owned McCann. The effort to win McCann actually turned into a bigger expansion plan in the implementation process. Dollof, who is skilled in diplomacy, persuaded all parties concerned to "rebel" McCann and his four teams, namely Minneapolis Lakers, Westburg Nisai Team, Rochester Royal Team and Indianapolis Pacers, from NBL to BAA. In the following season of 1949-195, all the remaining six teams of NBL joined BAA, while the Providence Steam Engine Team, one of the founding teams of BAA, announced its dissolution. In the 1949-195 season, after the annexation of NBL, BAA changed its name to NBA, divided its 17 teams into three divisions, and began a new development course of American professional basketball. With his determination and foresight, Dollof became the president of the NBA, which made the NBA embark on a smooth road of steady development from a difficult entrepreneurial period. The NBA in the 195s was a "George Macon" era.

He and his Minneapolis Lakers won the BAA championship in the first season (1948-1949) when they joined BAA from NBL. In the six years from 1948 to 1954, except for the NBA championship in 195-1951, which was taken away by Rochester Royals, the other five times were won by the Lakers led by Macon. In the second half of 1954, with the retirement of George McCann, the championship position of the Lakers was replaced by the newly rising teams such as St. Louis, but the great "McCann era" remained in the history of NBA and people's hearts, because only George McCann could make the organizer (NBA) change the size of the 3-second zone and the height of the basket (from 3.5 meters to 3.66 meters) for him.

In the late 195s, when there was no reference selection data to judge a player's talent, Arnold Reid Auerbach, the coach of Boston Celtics, traded two excellent strikers, De Macaulay and Cliff Hagen, for Russell's draft pick with the St. Louis Hawks, and won the god pitcher Tom Heinsohn in the 1956 draft. It formed a strong lineup with Kusi Shaman as the main defender, Heinsohn as the main striker and Russell as the main center, and became an impeccable team in all positions. In 1957, it beat the St. Louis Hawks 4-3 and won the championship for the first time, which also accumulated strength and experience for the Celtics' glory in the 196s. It is worth mentioning that in 1958, the St. Louis Hawks increased their strength because of the tacit cooperation between Macaulay Hagen and superstar bob pettit. In the finals, they defeated the Celtics 4-2 to win the championship and got revenge for last year. However, such a thing has not happened again.

In p>1952, due to the lethargy of NBA games, the game tended to evolve into foul wars and free throw wars. Danny Biancson, the boss of Syracuse National Team, proposed a 24-second system to limit the time for athletes to hold the ball, that is, if the winning team didn't shoot within 24 seconds, it would lose the opportunity to control the ball by the other team. This system was tried out in the 1954-1955 season, and the average score of each team in the first season increased by 13.6 points to 93.1 points. Three years later, the average NBA score exceeded 1 points. At the same time, it is stipulated that the number of fouls in a game shall not exceed 6 times. If a team has fouled six times in a game, the corresponding free throws will be changed from two to three from the seventh foul. The formulation of these new rules has greatly improved the appreciation of the NBA.

The NBA in the 196s

The NBA in the 196s belonged to Reed auerbach and his Boston Celtics. They won an incredible "eight consecutive championships" from 1959 to 1966, and they won the championship twice in 1968 and 1969, writing down the history of the "green dynasty" NBA. At this time, in 1964, the NBA expanded the width of the restricted area to 6 feet, creating a new life space for basketball.

In the late 195s, coached by "Cardinal" Reed auerbach, the Boston Celtics had begun to show their king's demeanor. After the Celtics won the first NBA championship in their history in 1957, auerbach continued to play his "Bole" role, and selected a batch of fresh blood for the team: Frank Ramsey, Sam Jones, Tom Sanders and john havlicek. Together with Russell, Shaman, Cousy and Heindern, these players made the Celtics strong and started their golden age. Although elgin baylor, regarded as the most skillful scorer, settled in Minneapolis Lakers in 1958, wilt chamberlain joined Philadelphia Warriors in 1959 and oscar robertson came to Cincinnati in 196, the Boston Celtics were invincible in the NBA in the 196s.

from 1959 to 196, the Boston Celtics won eight NBA championships in a row. This incredible "eight consecutive championships" is the storm and waves set off by the Celtics, a "green dynasty", which is unparalleled in NBA history. In these eight seasons, the Celtics won an average of 57.6 games in the regular season every season, and never lost more than 26 games. In the 1959 finals, the Celtics beat the Minneapolis Lakers 4-. In 196, they beat the St. Louis Hawks 122-13 in the seventh game of the finals. After a year, he dropped the St. Louis Hawks again with a score of 4:1. In the seventh game of the 1962 finals, they beat the Los Angeles Lakers (the original Minneapolis Lakers) by 11:17. In fact, once they entered the semi-finals, the Celtics became extremely strong. In the 1963-1964 season, the Cincinnati Royal Team led by Robertson, who was also in the Eastern District, achieved an impressive record of 55 wins in the regular season, only four games less than the Celtics. In the Eastern Conference semi-final, it was defeated by 1:4, with an average loss of 13 points per game. In 1964-1965, the Boston Celtics still won the championship. However, in the following two years, he fought very hard on the road to winning the championship, which really benefited from auerbach's foresight. In that year's regular season, the Philadelphia 76ers, with their talents Chamberlain and Cunningham, had the strength to compete with Boston. They won one more game than the Celtics and won the first place in the Eastern Conference, forcing the Celtics to fight with the Cincinnati Royal in the first round of the semi-finals, while they took advantage of it. This is also the first time in 1 years that the Celtics entered the semi-finals as the second place instead of the Eastern Conference champion. Boston and Cincinnati played five games before they won hard. In the Eastern Conference finals, he played against the Philadelphia 76ers and swept the 76ers who lost their morale 4-1, reaching the finals. In the finals, the Celtics and the old rival Los Angeles Lakers also played hard, losing at home in the first game. Since then, auerbach, who will retire in the 1966 playoffs, suddenly announced that Russell would take his place in the 1966-1967 season and become the first black coach in NBA history. After that, the Celtics' morale was greatly boosted and they won three games in a row. In the end, they defeated the Lakers 4-3 and completed their eight consecutive championships. 1966-
