NBA Finals

The NBA Finals is the annual championship series of the National Basketball Association (NBA). The Eastern and Western Conference champions play a best-of-seven series to determine the league champion. The team that wins the series is awarded the Larry O'Brien Championship Trophy, which replaced the original Walter A. Brown Trophy in 1976–77, though under the same name until 1984.

The series was initially known as the BAA Finals prior to the 1949–50 season when the Basketball Association of America (BAA) merged with the National Basketball League (NBL) to form the NBA. The competition oversaw further name changes to NBA World Championship Series from 1950 to 1985, as well as a brief stint as the Showdown, before settling on NBA Finals in 1986. Since 2018, it has been officially known as the NBA Finals presented by YouTube TV for sponsorship reasons.

The NBA Finals was initially structured in a 2–2–1–1–1 format. In 1985, to ease the amount of cross-country travel, it was changed to a 2–3–2 format, in which the first two and last two games of the series were played at the arena of the team who earned home-court advantage by having the better record during the regular season. In 2014, the 2–2–1–1–1 format was restored. The team with the better regular season record hosts the first two games and the other team hosts the next two games. If needed, the remaining three are played at each team's home arena alternately, starting with the arena of the team with the better regular season record.

A total of 21 franchises have won the NBA Finals, with the Boston Celtics winning the most recent and most in the NBA thus far with 18 total.
