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 game 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 1977, though under the same name. 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. This team 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. A total of 19 franchises have won the NBA Finals, with the Golden State Warriors winning the most recent title in 2022. The Los Angeles Lakers and the Boston Celtics hold the record for the most victories, having both won the competition 17 times. The Boston Celtics also won the most consecutive titles, winning eight in a row from 1959 to 1966. The Los Angeles Lakers have competed in the NBA Finals the most times, with 32 appearances. The Eastern Conference has provided the most champions, with 38 wins from 10 franchises; the Western Conference has 35, from nine franchises. From Wikipedia
