Other developments

In 2001, an affiliated minor league, the National Basketball Development League, now called the NBA G League, was created.

Two years after the Hornets' move to New Orleans, the NBA returned to North Carolina, as the Charlotte Bobcats were formed as an expansion team in 2004.

The Hornets temporarily moved to Oklahoma City in 2005 for two seasons because of damage caused by Hurricane Katrina. The team returned to New Orleans in 2007.

A new official game ball was introduced on June 28, 2006, for the 2006–07 season, marking the first change to the ball in over 35 years and only the second ball in 60 seasons. Manufactured by Spalding, the new ball featured a new design and new synthetic material that Spalding claimed offered a better grip, feel, and consistency than the original ball. However, many players were vocal in their disdain for the new ball, saying that it was too sticky when dry, and too slippery when wet.

Commissioner Stern announced on December 11, 2006, that beginning January 1, 2007, the NBA would return to the traditional leather basketball in use prior to the 2006–07 season. The change was influenced by frequent player complaints and confirmed hand injuries (cuts) caused by the microfiber ball. The Players' Association had filed a suit on behalf of the players against the NBA over the new ball. As of the 2017–18 season, the NBA team jerseys are manufactured by Nike, replacing the previous supplier, Adidas. All teams will wear jerseys with the Nike logo except the Charlotte Hornets, whose jerseys will instead have the Jumpman logo associated with longtime Nike endorser Michael Jordan, who owns the Hornets.

The Federal Bureau of Investigation (FBI) began an investigation on July 19, 2007, over allegations that veteran NBA referee Tim Donaghy bet on basketball games he officiated over the past two seasons and that he made calls affecting the point spread in those games. On August 15, 2007, Donaghy pleaded guilty to two federal charges related to the investigation. Donaghy claimed in 2008 that certain referees were friendly with players and "company men" for the NBA, and he alleged that referees influenced the outcome of certain playoff and finals games in 2002 and 2005. NBA commissioner David Stern denied the allegations and said Donaghy was a convicted felon and a "singing, cooperating witness". Donaghy served 15 months in prison and was released in November 2009. According to an independent study by Ronald Beech of Game 6 of the 2002 Western Conference Finals between the Los Angeles Lakers and Sacramento Kings, although the refs increased the Lakers' chances of winning through foul calls during the game, there was no collusion to fix the game. On alleged "star treatment" during Game 6 by the referees toward certain players, Beech claimed, "there does seem to be issues with different standards and allowances for different players."

The NBA Board of Governors approved the request of the Seattle SuperSonics to move to Oklahoma City on April 18, 2008. The team, however, could not move until it had settled a lawsuit filed by the city of Seattle, which was intended to keep the SuperSonics in Seattle for the remaining two seasons of the team's lease at KeyArena. Following a court case, the city of Seattle settled with the ownership group of the SuperSonics on July 2, 2008, allowing the team to move to Oklahoma City immediately in exchange for terminating the final two seasons of the team's lease at KeyArena. The Oklahoma City Thunder began playing in the 2008–09 season.

The first outdoor game in the modern era of the league was played at the Indian Wells Tennis Garden on October 11, 2008, between the Phoenix Suns and the Denver Nuggets.

The first official NBA league games on European ground took place in 2011. In two matchups, the New Jersey Nets faced the Toronto Raptors at the O2 Arena in London in front of over 20,000 fans.

After the 2012–13 season, the New Orleans Hornets were renamed the Pelicans. During the 2013–14 season, Stern retired as commissioner after 30 years, and deputy commissioner Adam Silver ascended to the position of commissioner. During that season's playoffs, the Bobcats officially reclaimed the Hornets name, and by agreement with the league and the Pelicans, also received sole ownership of all history, records, and statistics from the Pelicans' time in Charlotte. As a result, the Hornets are now officially considered to have been founded in 1988, suspended operations in 2002, and resumed in 2004 as the Bobcats, while the Pelicans are officially treated as a 2002 expansion team. (This is somewhat similar to the relationship between the Cleveland Browns and Baltimore Ravens in the NFL.)

Donald Sterling, who was then-owner of the Los Angeles Clippers, received a lifetime ban from the NBA on April 29, 2014, after racist remarks he made became public. Sterling was also fined US$2.5 million, the maximum allowed under the NBA Constitution.

Becky Hammon was hired by the San Antonio Spurs on August 5, 2014, as an assistant coach, becoming the second female coach in NBA history but the first full-time coach. This also makes her the first full-time female coach in any of the four major professional sports in North America.

The NBA announced on April 15, 2016, that it would allow all 30 of its teams to sell corporate sponsor advertisement patches on official game uniforms, beginning with the 2017–18 season. The sponsorship advertisement patches would appear on the left front of jerseys, opposite Nike 's logo, marking the first time a manufacturer's logo would appear on NBA jerseys, and would measure approximately 2.5 by 2.5 inches. The NBA would become the first major North American professional sports league to allow corporate sponsorship logos on official team uniforms, and the last to have a uniform manufacturer logo appear on its team uniforms. The first team to announce a jersey sponsorship was the Philadelphia 76ers, who agreed to a deal with StubHub.

On July 6, 2017, the NBA unveiled an updated rendition of its logo; it was largely identical to the previous design, except with revised typography and a "richer" color scheme. The league began to phase in the updated logo across its properties during the 2017 NBA Summer League.

The NBA also officially released new Nike uniforms for all 30 teams beginning with the 2017–18 season. The league eliminated "home" and "away" uniform designations. Instead, each team would have four or six uniforms: the "Association" edition, which is the team's white uniform, the "Icon" edition, which is the team's color uniform, and the "Statement" and "City" uniforms, which most teams use as an alternate uniform. In 2018, the NBA also released the "Earned" uniform.

In 2018, Adam Silver showed support in the Supreme Court's decision to overturn a federal ban on sports betting. Silver thought it would bring greater transparency and integrity as well as business opportunities. Before naming DraftKings and FanDuel co-official sports betting partners of the NBA in 2021, the NBA first named MGM as the exclusive official gaming partner of the NBA and WNBA—the first major American sports league to do so. With a deal between the 76ers and then-sportsbook FOX Bet as the first agreement between an NBA team and a sportsbook app, more teams partnered with operators thereafter. This early acceptance of sports betting translated to basketball being the most bet on sport in the United States over football in 2023.
