Changes

The series follows the survivors of Oceanic Flight 815, which crashes on an unidentified island in the Pacific Ocean. The group of strangers must learn to cooperate in order to survive the island's challenges, which are vastly more complicated than initially thought. Despite the standard "desert island" scenario, the plot involves much more than mere survival against the elements, with the castaways encountering several mysteries and ever-deepening conspiracies to deal with, as well as bizarre occurences and mysterious phenomena meeting them at every turn.

In the first three seasons, each episode typically centered around one character, with events on the island mixed with flashbacks to important parts of that person's life before the crash. Later in the series, however, this formula was altered in various ways that were appropriate to the changing mechanics of the storytelling.

''Lost'' began its first season on September 22, 2004, and is scheduled to end with its sixth season in May 2010. The announcement for the show's end date, including the number of remaining episodes and layout of the remaining seasons, was made in May 2007, close to the end of the show's third season. The show's creators had been urging the network to agree to this relatively rare arrangement for some time, and explaining this move, executive producer Damon Lindelof remarked that "We always envisioned 'Lost' as a show with a beginning, middle and end. By officially announcing exactly when that ending will be, the audience will now have the security of knowing that the story will play out as we've intended."<ref>http://web.archive.org/web/20070510030616/http://www.abcmedianet.com/assets/pr%5chtml/050707_01.html</ref>
