Sequel

The Marvelous Land of Oz sequel to Wizard of Oz was an official sequel novel written to satisfy popular demand

The origin of the sequel as it is conceived in the 21st century developed from the novella and romance traditions in a slow process that culminated towards the end of the 17th century.

The substantial shift toward a rapidly growing print culture and the rise of the market system by the early 18th-century meant that an author's merit and livelihood became increasingly linked to the number of copies of a work he or she could sell. This shift from a text-based to an author-centered reading culture[18] led to the "professionalization" of the author – that is, the development of a "sense of identity based on a marketable skill and on supplying to a defined public a specialized service it was demanding."[19] In one sense, then, sequels became a means to profit further from previous work that had already obtained some measure of commercial success.[20] As the establishment of a readership became increasingly important to the economic viability of authorship, sequels offered a means to establish a recurring economic outlet.

In addition to serving economic profit, the sequel was also used as a method to strengthen an author's claim to his literary property. With weak copyright laws and unscrupulous booksellers willing to sell whatever they could, in some cases the only way to prove ownership of a text was to produce another like it. Sequels in this sense are rather limited in scope, as the authors are focused on producing "more of the same" to defend their "literary paternity".[19] As is true throughout history, sequels to novels provided an opportunity for authors to interact with a readership. This became especially important in the economy of the 18th century novel, in which authors often maintained readership by drawing readers back with the promise of more of what they liked from the original. With sequels, therefore, came the implicit division of readers by authors into the categories of "desirable" and "undesirable"—that is, those who interpret the text in a way unsanctioned by the author. Only after having achieved a significant reader base would an author feel free to alienate or ignore the "undesirable" readers.[19]

This concept of "undesirable" readers extends to unofficial sequels with the 18th century novel. While in certain historical contexts unofficial sequels were actually the norm (for an example, see Arthurian literature), with the emphasis on the author function that arises in conjunction with the novel many authors began to see these kinds of unauthorized extensions as being in direct conflict with authorial authority. In the matter of Don Quixote (an early novel, perhaps better classified as a satirical romance), for example, Cervantes disapproved of Alonso Fernández de Avellaneda's use of his characters in Second Volume of the Ingenious Gentleman Don Quixote of La Mancha, an unauthorized sequel. In response, Cervantes very firmly kills the protagonist at the end of the Second Part to discourage any more such creative liberties.[21] Another example is Samuel Richardson, an 18th-century author who responded particularly strongly against the appropriation of his material by unauthorized third parties. Richardson was extremely vocal in his disapproval of the way the protagonist of his novel Pamela was repeatedly incorporated into unauthorized sequels featuring particularly lewd plots. The most famous of these is Henry Fielding's parody, entitled Shamela.[22]

In To Renew Their Former Acquaintance: Print, Gender, and Some Eighteenth Century Sequels, Betty Schellenberg theorizes that whereas for male writers in the 18th century sequels often served as "models of paternity and property", for women writers these models were more likely to be seen as transgressive. Instead, the recurring readership created by sequels let female writers function within the model of "familiar acquaintances reunited to enjoy the mutual pleasures of conversation", and made their writing an "activity within a private, non-economic sphere". Through this created perception women writers were able to break into the economic sphere and "enhance their professional status" through authorship.[19]

Dissociated from the motives of profit and therefore unrestrained by the need for continuity felt by male writers, Schellenberg argues that female-authored sequel fiction tended to have a much broader scope. He says that women writers showed an "innovative freedom" that male writers rejected to "protect their patrimony". For example, Sarah Fielding's Adventures of David Simple and its sequels Familiar Letters between the Principal Characters in David Simple and David Simple, Volume the Last are extremely innovative and cover almost the entire range of popular narrative styles of the 18th century.[23]

As the cost of developing a triple-A video game has risen,[24][25][26] sequels have become increasingly common in the video game industry.[27] Today, new installments of established brands make up much of the new releases from mainstream publishers and provide a reliable source of revenue, smoothing out market volatility.[28] Sequels are often perceived to be safer than original titles because they can draw from the same customer base, and generally keep to the formula that made the previous game successful.

Movie sequels do not always do as well at the box office as the original, but they tend to do better than non-sequels, according to a study in the July 2008 issue of the Journal of Business Research. The shorter the period between releases, the better the sequel does at the box office. Sequels also show a faster drop in weekly revenues relative to non-sequels.[29]

Sequels are most often produced in the same medium as the previous work (e.g. a film sequel is usually a sequel to another film). Producing sequels to a work in another medium has recently become common, especially when the new medium is less costly or time-consuming to produce.

A sequel to a popular but discontinued television series may be produced in another medium, thereby bypassing whatever factors led to the series' cancellation.

Some highly popular movies and television series have inspired the production of multiple novel sequels, sometimes rivaling or even dwarfing the volume of works in the original medium.

For example, the 1956 novel The Hundred and One Dalmatians, its 1961 animated adaptation and that film's 1996 live-action remake each have a sequel unrelated to the other sequels: respectively The Starlight Barking (1967), 101 Dalmatians II: Patch's London Adventure (2003, direct to video) and 102 Dalmatians (2000).
