Miniseries (also mini-series) is a term that usually refers to a television program that tells a story in a predetermined number of episodes. It may also refer to similar treatment of a comic book story, although that is more commonly known as a "limited series".
A miniseries is distinguished from a soap opera or an ongoing television series, which do not usually have a predetermined number of episodes and may continue for several years. Before the term was coined in the USA in the late 1970s, the ongoing episodic form was always called a "serial", just as a novel appearing in episodes in successive editions of magazines or newspapers is called a serial. In Britain, miniseries are often still referred to as serials.
Several commentators have offered more precise definitions of the term. In Halliwell's Television Companion, Leslie Halliwell and Philip Purser argue that miniseries tend to "appear in four to six episodes of various lengths", whilst Stuart Cunningham in Textual Innovation in the Australian Historical Mini-series defines a miniseries as, "a limited run program of more than two and less than the 13-part season or half season block associated with serial or series programming." In Television: A History, Francis Wheen states, "Both soap operas and primetime series cannot afford to allow their leading characters to develop, since the shows are made with the intention of running indefinitely. In a miniseries on the other hand, there is a clearly defined beginning, middle, and end (as in a conventional play or novel), enabling characters to change, mature, or die as the serial proceeds."
According to Francis Wheen, it was the American success in 1969–1970 of the British 26-episode serial The Forsyte Saga (1967) that made US TV executives realize that finite stories based on novels could be popular and could provide a boost to weekly viewing figures. In North America the form began in the spring of 1974 with the CBC's eight-part serial The National Dream, based on Pierre Berton's novel, and ABC's three-part QB VII, based on the novel by Leon Uris. Following these initial forays, broadcasters used miniseries to bring other books to the screen. Rich Man, Poor Man, based on the novel by Irwin Shaw, was broadcast in 12 one-hour episodes in 1976 by ABC. Alex Haley's Roots in 1977 can fairly be called the first blockbuster success of the format. Its success in the USA was partly due to its schedule: the 12-hour duration was split into eight episodes broadcast on consecutive nights, resulting in a finale with a 71 percent share of the audience and 130 million viewers, which at the time was the highest rated TV program of all time. TV Guide (April 11 – April 17, 1987) called 1977's Jesus of Nazareth "the best miniseries of all time" and "unparalleled television".
Miniseries were popular through the 1990s on the Big Three television networks, often as big-budget ratings-grabbing efforts scheduled for sweeps months; however, the use of the format declined quickly after approximately 2000 (coinciding with a similar collapse in producing made-for-TV movies) because of budgetary concerns. The format has made somewhat of a comeback on cable; History, for example, has had some of its greatest successes with miniseries such as America: The Story of Us, Hatfields & McCoys and The Bible.
A comic book miniseries (also referred to as a "limited series") is a commonly used storytelling format that allows creators to tell a single story focusing on a character or set of characters over the course of a predetermined number of issues, as opposed to an ongoing series which tells multiple stories or the intertwined stories of multiple characters over an unlimited number of issues. A comics miniseries may stand apart from other material produced by the same publisher (e.g., Watchmen), or may be heavily intertwined with other stories set in the same fictional universe (Civil War). Most miniseries range in length from two to 12 issues; a story contained in a single issue is termed a one-shot. At one time, DC Comics used the term "maxi-series" for a 12-issue miniseries, but this term has since been abandoned. 52 was arguably the longest comic book miniseries at the time it was released, running for 52 weekly issues; DC Comics has since used the 52-part weekly series structure for other long-running miniseries.
Other long-running comic book series have ultimately told finite stories but without a predetermined number of issues. For example, Neil Gaiman's Sandman told a complex story that lasted 75 issues. Cerebus the Aardvark ran for 300 issues, a goal that creator Dave Sim set for himself fairly early in the series' run, but he did not plan this limitation from the beginning. These are not considered miniseries, partly because of their sheer size and partly because no fixed number of issues was announced at the outset. Similar to a cancelled television series, a series intended to be ongoing that is discontinued after twelve or fewer issues (usually due to poor sales) is not considered a miniseries, though they are sometimes described as such by the publisher after the cancellation is announced.
