The Oklahoma City Thunder is an American professional basketball franchise based in Oklahoma City, Oklahoma.
 It plays in the Northwest Division of the Western Conference in the National Basketball Association (NBA).
 It was known as the Seattle SuperSonics from 1967 to 2008.
 The team plays its home games at the Chesapeake Energy Arena.
 As of October 2008, the Thunder is currently owned by Professional Basketball Club LLC and coached by Billy Donovan, with Sam Presti as its general manager.
 The team was formed in 1967.
 After spending 41 seasons in Seattle, Washington, the SuperSonics moved to Oklahoma City.
 Owner Clay Bennett, who purchased the team in 2006, sought to get public funding for a new arena in Seattle, or a major renovation of the KeyArena in 2007.
 After failing to do so, he decided to move the team to Oklahoma City.
 Seattle sued Bennett's group to enforce the lease that required the team to stay until 2010.
 The two sides reached a $45 million settlement to pay off the team's lease with KeyArena in July 2008.
