The sixth and final season of the American
serial drama television series Lost commenced airing in the
United States and
Canada on February 2, 2010.
The sixth-season premiere was the first to climb in the ratings year-over-year since the second season, drawing 12.1 million viewers.
The season aired Tuesdays at 9:00 from February 2 to May 18. The series finale aired on Sunday, May 23, 2010.
The finale ran two-and-a-half hours starting at 9/8c; pushing the local news back a half-hour, followed by the previously announced post-finale special, Jimmy Kimmel Live: Aloha to Lost, at 12:05 a.m.
The season continues the stories of the survivors of the fictional September 22, 2004 crash of
Oceanic Airlines Flight 815 on a mysterious island in the South Pacific. The survivors must deal with two outcomes of the detonation of a nuclear bomb on the island in the 1970s. While the on-island story continues, "flash sideways"
show a second timeline, in which Flight 815 never crashes. The season was released on DVD and Blu-ray on August 24, 2010, alongside a complete series boxset.
