The league was founded in New York City on June 6, 1946, as the Basketball Association of America (BAA). It changed its name to the National Basketball Association on August 3, 1949, after merging with the competing National Basketball League (NBL). The NBA's regular season runs from October to April, with each team playing 82 games. Its playoffs extend into June. NBA players are the world's best paid athletes by average annual salary per player.
In basketball, a double is the accumulation of a double-digit number total in one of five statistical categories—points, rebounds, assists, steals, and blocked shots—in a game. Multiple players usually score double-digit points in any given basketball game; the double nomenclature is usually reserved for when a player has double-digit totals in more than one category. A double-double is the accumulation of a double-digit number total in two of the five categories in a game. The most common double-double combination is points-rebounds, followed by points-assists. Since the 1985–86 season, Karl Malone leads the National Basketball Association (NBA) in the points-rebounds combination with 811 and John Stockton leads the points-assists combination with 709. A triple-double is the accumulation of a double-digit number total in three of the five categories in a game. The most common way to notch triple-double is through points, rebounds, and assists. Oscar Robertson leads the all-time NBA list with 181. A quadruple-double is the accumulation of a double-digit number total in four of the five categories in a game. This has occurred four times in the NBA. A quintuple-double is the accumulation of a double-digit number total in all five categories in a game. One known quintuple-double has occurred at the U.S. high school level, when Tamika Catchings recorded one in 1997. A similar accomplishment is the five-by-five, which is the accumulation of at least five points, five rebounds, five assists, five steals, and five blocks in a game. In the NBA, only Hakeem Olajuwon and Andrei Kirilenko have accumulated multiple five-by-fives since the 1985–86 season.
