The National Basketball Association (NBA) Finals is the championship series to the NBA and the conclusion of its postseason. All Finals Are played at a best-of-seven format, and are contested between the winners of their Eastern Conference and the Western Convention (formerly Divisions before 1970), except in 1950 when the Eastern Division champion faced the winner between the Western and Central Division winners.
