The Seattle SuperSonics, also known as the Sonics, were a professional basketball team based in Seattle. The team played from 1967 to 2008. They were members of the Western Conference of the National Basketball Association (NBA) from 1970 onward; the team played in the conference's Pacific Division from 1970 to 2004 and the Northwest Division from 2004 to 2008. The Sonics joined the NBA as an expansion team in 1967 and were named for the supersonic airliner under development by Boeing, which was later cancelled. They played for their first eleven seasons at the Seattle Center Coliseum, which was built for the 1962 World's Fair and had a seating capacity of 12,595. The team moved in 1978 to the Kingdome, a multipurpose stadium shared with other sports teams, and set NBA attendance records there during a seven-season stay. The Sonics hosted twenty Kingdome games with crowds larger than 30,000 and drew a league-record 40,172 spectators at a 1980 playoffs game.
The team returned to the Seattle Center Coliseum in 1985 as attendance at the Kingdome declined and the stadium's scheduling and layout caused issues for fans. A major renovation of the Coliseum began in 1994 and displaced the Sonics, who played for two seasons at the Tacoma Dome, a suburban arena that was expanded to 16,296 seats. The renovated Coliseum, renamed to KeyArena, had the NBA's smallest seating capacity at 17,072 and hosted its first regular season game on November 4, 1995. The team played their final home game at KeyArena on April 13, 2008. After the end of the 2007–08 season, the Sonics were relocated by its new ownership group to Oklahoma City. A lawsuit to halt the relocation and enforce the team's 15-year lease at KeyArena was filed by the Seattle city government but dropped as part of a settlement in July 2008. The team has played since the 2008–09 season as the Oklahoma City Thunder; as part of the settlement, the SuperSonics name and history was left with the city for use by a future team.
In their 41 seasons as an NBA team, the SuperSonics had an all-time regular season record of 1,745 wins and 1,585 losses; in the playoffs, they had 107 wins and 110 losses. They reached the postseason 22 times and played in three NBA Finals, winning one league championship in 1979. The Sonics were the first team from Washington state to win a major professional sports championship since the Seattle Metropolitans in the 1917 Stanley Cup. Their .524 winning percentage was also historically the best among professional teams in the Seattle area, surpassing the Seattle Seahawks and Seattle Mariners. The team's all-time points leader is Gary Payton with 18,207 points; he also holds the most assists in Sonics history at 7,384.
The Sonics had a 23–59 record during their inaugural season and finished with the NBA's second-worst record, narrowly ahead of fellow expansion team San Diego Rockets. The team were below .500 for their first four seasons and had their first winning season in 1971–72, where they earned a 47–35 record. The Sonics clinched their first playoff berth in the 1974–75 season, which was followed by consecutive NBA Finals in 1978 and 1979 against the Washington Bullets. Seattle lost the first final, but defeated Washington in the rematch after finishing first in the Western Conference. Lenny Wilkens, who led the team to both finals appearances, was replaced as head coach in 1985 after missing the playoffs by finishing with a 31–51 record, which his successor Bernie Bickerstaff equaled the following season. The Sonics made an unexpected run to the Western Conference final in the 1987 playoffs, only to lose to the Los Angeles Lakers.
The 1990s brought more consistent success, including eight consecutive playoff appearances, with head coach George Karl and new players Shawn Kemp and Gary Payton, both acquired in the draft. The Sonics finished as the top seed in the 1993–94 season with a 63–19 record, but lost in a major upset to the eighth-seeded Denver Nuggets in the opening round of the playoffs. The team reached the 1996 NBA Finals—their third and final appearance—after clinching first in the Western Conference standings but lost to the Chicago Bulls in six games. The Sonics were eliminated in the conference semifinals two more times under Karl before he left the team along with Kemp by 1998. The team, now under coach Paul Westphal, missed the playoffs in the shortened 1998–99 season, but returned the following year as a seventh-seed. Westphal was replaced early in the 2000–01 season by assistant coach and former Sonics player Nate McMillan, who led the team through rebuilds and to their two final playoff appearances: in 2002–03 and 2004–05 as the Northwest Division champions with 52 wins. The team's final three seasons in Seattle all finished with losing records and no playoff berths under the three different head coaches. The Sonics had 20 wins and 62 losses during their 2007–08 season, their worst record in franchise history, shortly before moving to Oklahoma City.
