In which year did the Seattle SuperSonics win the NBA championship?

Context:
Seattle SuperSonics won the NBA championship in 1979. The franchise won Western Conference titles in 1978, 1979 and 1996; and six divisional titles—their last being in 2005—five in the Pacific Division and one in the Northwest Division. The franchise attained a 1,745–1,585 (.524) regular season win–loss record, as well as a 107–110 (.493) playoff win–loss record during its time in Seattle.[citation needed] Both marks would rank in the top half of the NBA's all-time standings. Settlement terms of a lawsuit between the city of Seattle and Clay Bennett's ownership group stipulated SuperSonics' banners, trophies and retired jerseys remain in Seattle; the nickname, logo and color scheme are available to any subsequent NBA team that plays at KeyArena subject to NBA approval. The SuperSonics' franchise history, however, would be shared with Thunder.<|im_end|>
