Spin-Off

""'Spinoff!' Is there any word more thrilling to the human soul?""

- Troy McClure

Spinoffs are when part of a successful show, usually characters, but sometimes a general concept (first you have the Law, then you have the Order), are taken and given a second show of their own.

From a producer's perspective, it's a chance to explore other aspects of a concept. Actors can find opportunities to grow in their craft, as well as rise in importance by moving from just being part of an ensemble to having a show built around them. For the networks, it's a chance to establish a show with a built-in audience, making it that much easier for them to sell advertising.

Lots of spinoffs go on to be successful shows in their own right, sometimes even surpassing the parent series in popularity. Others crash and burn (Joanie Loves Chachi, anyone?), suggesting that there is no such thing as a sure thing. Nevertheless, networks keep trying them.

There are several main types of spinoffs:
 * 1) Where a character leaves a show and the two run concurrently. Characters Crossover from time to time.
 * 2) Where a show comes to an end and a character from it is given his or her own new show. Provides an opportunity to Retool the character as well.
 * 3) Where a character is brought on to an existing show simply in order to be spunoff, hopefully making some of the original audience into viewers of the new show (See Poorly-Disguised Pilot).
 * 4) The main character is revisited elsewhere in his narrative.
 * 5) Reimaginings - the concept is carried into a new show with the same basic premise but other factors and characters are completely new.
 * 6) Segment spin-offs - a recurring segment from the show becomes the main attraction.
 * 7) A type of Defictionalization - a Show Within a Show gets made into a real show of its own.
 * 8) The storyline on one show comes to an end, only to be continued in a new show with a different name.
 * 9) Official Fanzine Show - a trope usually applying to Reality TV, usually offering Behind The Scenes info or coverage that wouldn't fit into the main programme, often (but not always) broadcast immediately after the main show, on a sister channel.
 * 10) Online Spin-Off - A spin-off that's only shown online, sometimes overlaps with Segment Spin-Off, sometimes a spin-off In Name Only. Generally only an advert for the broadcast programme.
 * 11) Shared Continuity - more common nowadays, this spinoff generally carries no characters over from the show that spawned it, though both are in the same continuity that allows for Crossovers from the original.

Spin-offs are Older Than You Think. Plantagenet Palliser was a minor character in The Small House at Allington, one of the novels in the Barchester series by Anthony Trollope. Plantagenet Palliser became one of the main characters of Trollope's Palliser series, written in the 1860's and 1870's. And earlier than that, the character of Falstaff, from Henry IV parts 1 and 2, was given his own play, at Royal request, by Shakespeare.

Anime and Manga

 * Fist of the North Star (Hokuto no Ken) has a series of spinoff works known as the Hokuto no Ken Gaiden series, which centers around side-characters from the original manga, depicting what happened to them prior to the events of Hokuto no Ken, although they do deviate from canon a bit. Almost all of them, with the exception of Yuria Gaiden, were published in Weekly Comic Bunch (the manga anthology that serializes Souten no Ken) at the time the Legends of the True Savior movies were released.

 * Grey's Anatomy → Private Practice
 * All in The Family, was the king of this trope and spun off no fewer than three shows some of which had their own spinoffs!: The Jeffersons, Maude, and Maude's housekeeper Florida, was spun off into Good Times. It also was an example of #8 below, as All In The Family became Archie Bunker's Place. Similarly, but less successfully, the Jeffersons' housekeeper Florence received her own spin-off Checking In which was cancelled after one season.
 * Archie Bunker's Place itself had a one season spin-off Gloria that featured Archie's daughter Gloria, having divorced Mike, starting a new life in New York.
 * The Daily Show → The Colbert Report
 * Sort of; even though Stephen Colbert was on The Daily Show for eight years, his persona on that show was different from the character he plays on The Colbert Report. This is also a Defictionalization, since it started as a series of fake promos on The Daily Show.
