Lost (TV Series)

Lost is an American serial drama television series. It follows the lives of plane crash survivors on a mysterious tropical island, after a commercial passenger jet flying between Sydney, Australia and Los Angeles crashes somewhere in the South Pacific. For the first three seasons each episode typically featured a primary storyline on the island as well as a secondary storyline from a previous point in a character's life, though the introduction of shifts forward in time and other time-related plot devices somewhat changed this formula for the latter half of the series. The pilot episode was first broadcast on September 22, 2004 and since then four full seasons have aired, with the fifth currently in progress, and a sixth set to be the final in 2010. The show airs on the ABC Network in the United States, as well as on regional networks in many other countries.
