Kim Newman frequently uses this device, as does Stephen King. The works of James Branch Cabell, J.D. Salinger, William Faulkner, Margaret Laurence, Thomas Pynchon, Kurt Vonnegut, Mordecai Richler, Sir H. Rider Haggard, Edgar Rice Burroughs, Robert Heinlein, and Isaac Asimov also cross over with each other, linking different characters and settings together over a number of different works.
Illustrator Howard Pyle conceived his work ''Twilight Land'' as one such crossover. In it, a nameless narrator is transported to "Twilight Land" and meets famous fairy tale characters for a soirée in an inn: Mother Goose, Cinderella, Fortunatus (book), Fortunatus, Sinbad the Sailor, Aladdin, Askeladden, Boots, the The Brave Little Tailor, Valiant Little Tailor, and others gather in the framing device and tell each other adventurous tales featuring other literary personages.
French author Jules Lemaître wrote a sort of sequel to ''Cinderella'', named ''Princess Mimi'', where Cinderella's daughter is courted by Polyphemus and Charles Perrault's ''Hop-o'-My-Thumb''.
Public domain
It is also common for authors to 'crossover' characters who have passed into the public domain, and thus do not require copyright or royalty payments for their use in other works. ''The League of Extraordinary Gentlemen'' by Alan Moore and Kevin O'Neill (comics), Kevin O'Neill is another example of this, as all of the main characters and most of the secondary / background characters are fictional characters whose copyright has expired, and all are characters of different authors and creators brought together within one massive extended universe. Many of the works of Philip José Farmer's Wold Newton family sequences (which has also been explored and developed by other authors) also utilize and interweave numerous otherwise unrelated fictional characters into a rich family history by speculating familial connections between them (such as a blood-relationship between Sherlock Holmes and Tarzan). Roger Zelazny's novel ''A Night in the Lonesome October'' combines Sherlock Holmes, Doctor Frankenstein, Jack the Ripper, and the Cthulhu Mythos, although he never specifically identifies them as such ("The Count", "The Good Doctor", "Jack", etc.).
Occasionally, authors will include into crossovers classic fictional characters whose copyright is still held by the original authors (or at least their estates), but who are nevertheless considered iconic or 'mythic' enough to be recognised from a few character traits or descriptions without being directly named (thus not requiring royalties payments to be made to the copyright holder). A prominent example occurs within ''The League of Extraordinary Gentlemen, Volume One'', wherein a character who is clearly intended in appearance and description by other characters to be Dr. Fu Manchu appears as a significant villain; however, as this character was not in the public domain at the time of writing and the rights still held by the estate of his creator Sax Rohmer, he is not directly named as such in the work and is only referred to as 'the Devil Doctor'.
Television series
Between established shows
Crossovers involving principals can also occur when the characters have no prior relationship, but are related by time period, locale or profession. The ''Law and Order'' series, for example, afford a commonality of setting and profession which lends itself to crossovers, both within the franchise and in a wider universe. Following the cancellation of the
ABC soap opera ''One Life to Live'' and its high-rated finale, several characters crossed over into the network's remaining soap opera ''General Hospital'', remaining in the same timeline as their former show.
Between related shows
Though most common on shows of the same production company (see, for example, "Hurricane Saturday"), crossovers have also occurred because shows share the same distributor or television network. A notable example of this kind of link is that between ''Murder, She Wrote'' and ''Magnum, P.I.'' These shows were made by different companies, but owned by

's Must See TV, Thursday night schedule).
''Mad About You'' and ''Friends'' share another type of "network crossover". On rare occasions, networks have chosen to theme an entire night's programming around a crossover "event". In one case, a New York City Power outage, blackout caused by Paul Reiser's character on ''Mad About You'' was experienced by the characters on ''Friends'' and ''Madman of the People''. Such "event nights" can also be linked by a single character's quest across multiple shows on the same evening.
ABC attempted this kind of "event night" crossover with its TGIF (ABC), Friday night programming during the 1997 season. There, they proposed that the title character of ''Sabrina the Teenage Witch (1996 TV series), Sabrina the Teenage Witch'' should chase her cat, Salem Saberhagen, Salem, through ''Boy Meets World'', ''You Wish (TV series), You Wish'' and ''Teen Angel (1997 TV series), Teen Angel'' because it had run away with a "time ball" that was displacing each show through time.
In 2013, the Canadian crime drama series ''Republic of Doyle'' and ''Murdoch Mysteries'' produced a crossover,
which was complicated by the shows' incompatible historical settings; ''Murdoch Mysteries'' is a historical series set in the 1890s, while ''Republic of Doyle'' is set in the present day. The problem was solved by having the actors cross over as ''relatives'' of their primary characters; Allan Hawco appeared on the November 25, 2013 episode of ''Murdoch Mysteries'' as Jacob Doyle, a 19th-century ancestor of his regular character Jake Doyle, while Yannick Bisson appeared on a January 2014 episode of ''Republic of Doyle'' as Bill Murdoch, a 21st-century descendant of his regular character William Murdoch.
The earliest example of a crossover in children's television was PBS' 1971 program ''The Electric Company (1971 TV series), The Electric Company''.
Promotional cameos
Crossovers can take the form of a promotional cameo appearance, used to draw attention to another work of fiction, with little rational explanation in the context of the hosting show's narrative. When not clearly presented as parody, this is frequently scorned by fans as blatant commercialism. A notable example of this is ''

'' episode "A Star Is Burns", in which the character of Jay Sherman (from ''The Critic'') appeared. It originally aired on March 5, 1995, on FOX right before ''The Critic'' began its second season, its first season having aired on ABC. This episode was largely condemned by fans of ''The Simpsons'' as existing to promote ''The Critic'', an animated series considered inferior by comparison. Even ''Simpsons'' creator Matt Groening objected, preferring to remove his name from the credits of that particular episode in protest.
Various reactions, including Matt Groening's, to ''A Star Is Burns''
Spin-offs
In its simplest and most common form, a television crossover involves a starring character on a parent show appearing on a Spin-off (media), spin-off or vice versa because of established character relationships. An obvious example of this type of crossover occurred when Cliff Huxtable of ''The Cosby Show'' visited his daughter, Denise Huxtable, Denise, on ''A Different World (TV series), A Different World''.
More complex multi-production franchises can utilize crossovers of characters to serve as a device in establishing continuity in a shared fictional universe. This crossover is common in the Star Trek crossovers, ''Star Trek'' universe, where minor guest stars from one series have appeared as featured guest stars later ones. A good example of this crossover is that of the Klingons Kor (Star Trek), Kor, Koloth, and Kang (Star Trek), Kang. After the passage of about a century of narrative time, the three onetime adversaries of James T. Kirk, Captain Kirk appeared together in the ''Star Trek: Deep Space Nine'' episode, "Blood Oath (DS9 episode), Blood Oath" – as the Klingons and Federation had become allies in the century between, the former villains are now portrayed as heroes.
The distinction between "spin-off" and "crossover" is sometimes narrow. The two terms can become especially conflated if two shows are linked by a guest star with a single appearance. There is debate, for instance over whether ''Out of the Blue (1979 TV series), Out of the Blue'' is a spin-off of ''Happy Days'', or whether the star of ''Out of the Blue'' merely crossed over into ''Happy Days''.
Parodic crossovers
Often, the problems of bringing together two shows with different narrative ambitions make the writing of a crossover burdensome. Such difficulties are encountered by situation comedies that wish to crossover with television drama, dramatic television programs. The satirical crossover—ranging in length from a cameo to a full sketch comedy, comedy sketch or episode—is an extremely popular way of circumventing this problem. By various means, such crossovers typically avoid outcry from fans by being obvious parody or Homage (arts), homage. However, on rare occasion, the humor of such crossovers can be used by one show make a narrative point by capitalizing on the audience's experience of the other program.
Parodic crossovers can be directly established as being outside the continuity of one or all of the properties being crossed over. A good example is the crossover between ''The Simpsons

'' and ''The X-Files'', which was largely accepted as being outside standard ''X-Files'' continuity.
They can occur by virtue of a dream sequence, in which the characters of one show will appear as part of a dream had by a character on another show. This method was perhaps used most famously to explain to audiences that the entirety of ''Newhart'' had been the dream of Bob Newhart's character on ''The Bob Newhart Show''. It has more recently been used to demonstrate that cast members of ''The Young and the Restless'' appeared in a dream of a character on ''The King of Queens''.
Parodic crossovers can take the form of "joke, gag" cameos by characters of one property appearing on another. Crossovers of this type can also be completely wordless. This type of crossover is more common on animated programs, such as when Bender (Futurama), Bender found and ate Bart Simpson's shorts on ''Futurama
''Futurama'' is an American animated science fiction sitcom created by Matt Groening for the Fox Broadcasting Company and later revived by Comedy Central, and then Hulu. The series follows Philip J. Fry, who is cryogenically preserved for 1 ...
'', or Milhouse Van Houten, Milhouse had a talking Bender doll on ''The Simpsons''. This would seem to be another case when a popular franchise is acknowledged as fiction and not a crossover of the stories.
Perhaps the most obvious parodic crossover is found when characters from two series interact outside ''either'' series. This occurs most commonly on a sketch comedy show or as a humorous interlude on an award telecast. Such crossovers may sometimes involve the real actors—for example, a sketch on ''Royal Canadian Air Farce'' saw Yasir and Sarah from ''Little Mosque on the Prairie'' buying the gas station from ''Corner Gas'', with many of the characters in the sketch being portrayed by the shows' real actors—although they may also feature one genuine star from the show amid a cast comprised otherwise of the sketch show's own stable of actors.
Parodic crossovers can be used to lend verisimilitude to the fictional world of a program. Characters from a fictional television series may appear on a stylized version of an established non-fictional television series, such as game shows or reality shows. These crossovers between celebrity hosts and fictional characters are quite common on situation comedy, situation comedies. ''Mama's Family'' once appeared on ''Family Feud'' and the townsfolk of ''The Vicar of Dibley'' have had their heirlooms valuated on ''Antiques Roadshow'', for instance.
German crossover
One of the earlier instances of crossovers in TV productions outside the US is the episode ' (1990), which was produced by Westdeutscher Rundfunk, WDR and Deutscher Fernsehfunk, DFF as a crossover between the West Germany, West German crime series and the East Germany, East German crime series ''Polizeiruf 110''. Their respective popular heroes Horst Schimanski and Peter Fuchs join forces to solve a case in the turmoil of the time after the Berlin Wall#The fall, fall of the Berlin Wall. The episode was produced during the short transition period between the fall of the Berlin Wall and the German reunification, reunification of Germany.
