"Lost Starter Kit" is a video short from ABC's marketing department. It is part of the "Starter Kit" series of videos that attempt to bring new viewers of ABC's television programs quickly up to date on each series so that the events of the latest season are comprehensible. The Lost Starter Kit is just under five minutes long, and was available at the ABC website, often as part of commercial breaks during online streamed viewing of full episodes of their other television series. It was released prior to the premiere of Season 5, in November 2008 or earlier. It was later included on Disc 1 of the Season 5 DVD.
