Lost is an American television series created by Jeffrey Lieber, J. J. Abrams and Damon Lindelof, which originally aired on the American Broadcasting Company from September 22, 2004 to May 23, 2010. The series follows the lives of various groups and people, most importantly the survivors of the crash of a commercial passenger jet flying between Sydney and Los Angeles, on a mysterious tropical island somewhere in the South Pacific. Episodes of the early seasons typically feature a primary storyline on the island, as well as a secondary storyline from another point in a character's life.
Lost was produced by ABC Studios, Bad Robot Productions and Grass Skirt Productions. Throughout its run, the executive producers of the series were Lindelof, Abrams, Bryan Burk, Jack Bender, Edward Kitsis, Adam Horowitz, Jean Higgins, Elizabeth Sarnoff and Carlton Cuse. Due to its large ensemble cast and the cost of filming primarily on location in Oahu, Hawaii, the series was one of the most expensive on television. During its run, the series utilized the alternative reality games, The Lost Experience and Find 815 on the Internet, and references to the series appear in print, film, other television programs as well as Web media.
A critically-acclaimed and popular success, Lost was consistently ranked by US critics on their lists of top fives series of the year. The first season garnered an average of 15.69 million US viewers per episode on ABC. Although ratings lessened throughout its run, the series had stable ratings and the sixth season averaged over 11 million US viewers per episode.
