Cliffhanger

From Lostpedia

A cliffhanger ending is a plot device in which a movie, novel, or other work of fiction contains an abrupt ending, often leaving the main characters in a precarious or difficult situation. This type of ending is used to ensure that, if a next installment is made, audiences will return to find out how the cliffhanger is resolved. Many Lost episodes cut to commercial breaks or end on a cliffhanger.
