A season finale (British English: last in the series; Australian English: season final) is the final episode of a season of a television program. This is often the final episode to be produced for a few months or longer, and, as such, will try to attract viewers to continue watching when the series begins again.
A season finale may contain a cliffhanger ending to be resolved in the next season. Alternatively, a season finale could bring open-ended storylines to a close, "going out on a high" and similarly maintaining interest in the series' eventual return.
In the late 2000s, the terms "mid-season finale", "fall finale" and "winter finale" began being used by some cable and broadcast networks in the United States, to denote a series whose current season has been split into two halves in order to make room for a mid-season replacement series; generally when this occurs, the next first-run episode of the current season picks up a few months after the previous first-run episode aired. The "winter finale" definition is usually used to demarcate the hiatus of regular programming during the December Christmas and holiday season.
