rights holders to reap the financial reward of combining two or more popular, established properties. In other cases, the crossover can serve to introduce a new concept derivative of an older one. Crossovers generally occur between properties owned by a single holder, but they can, more rarely, involve properties from different holders, provided that the inherent legal obstacles can be overcome. They may also involve using characters that have passed into the

Unofficial

In contrast with legal crossovers, unofficial crossovers are created solely because of the artistic pleasure derived by their creators. Unofficial crossovers often take the form of fan-written fiction and fan art, but the trope is increasingly prevalent in amateur films and

. Whereas official crossovers are frequently stymied by such concerns as copyright, royalties payments, quality of writing and ownership of the characters, unofficial crossovers are unfettered by such concerns, so long as property holders do not exercise their right to enjoin the distribution of such material.

In comic book terminology, these "guest star" roles are common enough that they are generally not considered crossovers; rather, this short-term collaboration to fight crime is called a team-up. A crossover in comic book terms only occurs when a story spans more than one title. This has led to "crossover events" in which major occurrences are shown as affecting most or all of the stories in the shared universe; see Crossover comics.

Sonic and Mega Man were briefly tricked into fighting each other, but later joined forces and teamed up with other heroes to battle the doctors' forces, which included virtually every Robot Master introduced in the ''Mega Man'' games. The popularity of this crossover and the books involved led to a second crossover in 2015 entitled "Worlds Unite", which not only reunited Sonic and Mega Man, but also featured comics-exclusive characters from both of their books, the '' Mega Man X'' and '' Sonic Boom'' spinoff franchises and various other SEGA and Capcom franchises. This crossover was enabled by the conclusion of the first crossover, which saw a reboot to the Sonic books as their universe was drastically rewritten. Aftereffects of this included the Genesis Portals, gateways connecting worlds that would be exploited by ''Mega Man X'' villain Sigma and his minions, forcing a reunion between Sonic and Mega Man and an alliance between heroes of the various franchises involved. "Worlds Unite" spans not only the three series featured in the first crossover, but also includes the ''Sonic Boom'' comic series, which entered publication between the two crossovers. There are also intercompany crossovers, where characters owned by two different companies meet, such as those from DC and Marvel.

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. ''Law & Order: SVU'' has crossed over several times with ''Chicago P.D.'' and ''Chicago Fire'', as well as sharing a common character with ''Homicide: Life on the Street''.

Narrative rationales

On other occasions, crossovers between established shows can occur without a network or production commonality, but simply because there is some narrative rationale for the crossover. The appearance of detective John Munch (from NBC's '' Homicide: Life on the Street'') on Fox's ''The X-Files'' happened merely because the episode revolved around a crime scene in Baltimore, a logical place for characters on ''The X-Files'' to have encountered Munch. Munch would also appear on the TV series ''

'' crew. 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'' is a spin-off of '' Happy Days'', or whether the star of ''Out of the Blue'' merely crossed over into ''Happy Days''. '' Mako Mermaids'', a spinoff of '' H2O: Just Add Water'', featured a guest appearance by Rikki Chadwick, a main character from the former series, in its final two episodes, thus confirming that the spin off-acts as a sequel rather than a prequel or alternative storyline as many fans suspected.


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

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 ''

with a cameo by Professor Utonium. 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. Characters from ''King of the Hill (TV series), King of the Hill'' have appeared on ''

'' to comment on a peewee football game. Gag cameos may also include the appearance of an actor from another show, but not necessarily the character that the actor played. For instance, on the ABC/CBS show ''Family Matters (TV series), Family Matters'' during the closing credits of the episode "Scenes From a Mall" (Season 5, Episode 12), a scene which was shown earlier in the episode featuring Reginald VelJohnson is re-played, but this time with one of the child actors stating that he "looks like that fat guy from Fresh Prince," referring to James L. Avery, Sr., James Avery who played Judge Phillip Banks on NBC's ''The Fresh Prince of Bel-Air''. To the obvious surprise of the studio audience and VelJohnson, Avery walked onto the set with an angry look, being in on the staged joke himself. Ended the episode (but with the cameras filming still), VelJohnson and Avery hugged and smilingly greeted the public. 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 ''

'', 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. Such crossovers are generally immediately apparent as parodies to the audience—and in no way considered a part of either show's continuity—due to the need for the hosting show to approximate the sets and costumes of the satirized programs quickly and inexpensively. When Patrick Stewart appeared in a ''Star Trek: The Next Generation''/'' The Love Boat'' crossover on ''Saturday Night Live'', for instance, few ''Star Trek'' fans would have been fooled by the visual design into believing the event "counted" as an episode of the show. However, there are some cases of this type of parody having some canon (fiction), canonical resonance with viewers. For instance, the British charity appeal Comic Relief (charity), Comic Relief often contains parodic crossovers of a technically higher quality than the typical sketch show. Many of these ''Relief'' sketches are produced by the cast and crew of the actual programs being parodied, and hence appear to be "normal" episodes. A good example of this is the sketch, "BallyKissDibley", an 11-minute piece in which the leads of ''Ballykissangel'' appeared on the sets of ''The Vicar of Dibley'', alongside most of ''Dibley''s cast. Since the sketch derived its humor from all actors remaining in character, the extent to which these parodies "count" as part of either show's canon is more open to interpretation than most sketch crossovers. 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. In such cases, it is generally the non-fictional show which ends up being the most satirized, due to a need to compress the experience to its most recognizable elements. However, these crossovers can happen on dramatic television, such as when ''Blue Peter'' provided Exposition (literary technique), narrative exposition on ''The Sarah Jane Adventures''. Rarely, brief crossovers between two fictional programs can be used for this same purpose. In the episode, "Army of Ghosts", Peggy Mitchell was seen in a fictionalized scene from ''

Retroactive crossovers

Sometimes, crossovers occur even when there was no explicit intent to create them. Viewer interpretation can play into the size and complexity of crossovers. These sorts of crossovers involve no creation of additional material, but merely result from inferences drawn about existing filmed episodes. Usually they are a product of narrative ambiguity. Perhaps the best example of this was caused by the unusual ending to ''St. Elsewhere''. One interpretation of the ending scene of the final episode has been that the entire run of the program was a figment of autism, autistic character Tommy Westphall's imagination. This leads itself to a broad interpretation of the events of that series. Because the show had direct crossovers with twelve different programmes, and each one of these twelve had numerous ''other'' crossovers, linkages can be found from ''Elsewhere'' to 280 other shows, comprising what has been called "the Tommy Westphall Universe".
