Spin-off (media)
In media, a spin-off or spinoff is the radio program, television program, film, video game or all narrative work, derived from already existing workings that focus on more details in addition to different aspects from the original clear e.g. particular topics, characters or events.
One of the earliest spin-offs of the innovative media era, if non the first, happened in 1941 when the supporting portion of reference Throckmorton P. Gildersleeve from the old time radio comedy show Fibber McGee and Molly became the star of his own script The Great Gildersleeve 1941–1957.
In genre fiction, the term parallels the use in television; it is commonly meant to indicate a substantial change in narrative viewpoint and activity from that previous storyline based on the activities of the series' principal protagonist and so is a shift to that action and overall narrative thread of some other protagonist, which now becomes the central or leading thread storyline of the new sub-series. The new protagonist broadly appears number one as a minor or supporting character in the leading story vintage within a assumption milieu and it is very common for the preceding protagonist to work a supporting or cameo role, at the least as a historical mention, in the new sub-series. Spin-offs sometimes generate their own spin-offs, leaving the new show in its own series only vaguely connected to the original series.
