->''"It probably goes without saying, but just in case, I should point out that these are not plot-forwarding butts. Creator/VinDiesel never says, "Hey, Ludacris, Other Guy, get outta that car and come over here; we need to drive fast cars or those butts are going to '''explode'''!" [[Wrestling/DwayneJohnson The Rock]] never pulls over to the side of the road saying, "Damn, they're getting away with all of the car money. I'd be able to catch them, but I'm out of gas, and my car runs on butts." They serve no story function. Just butts for butts' sake."''

Characters in skimpy clothing, or skin-tight clothing, or none at all, under the assumption that it will attract or "reward" viewers. The character is usually [[MsFanservice female]], though fanservice of [[MrFanservice male]] characters is actually just as if not more common due to trends like ''BishonenJumpSyndrome''.

This is not just a fan term, but one used during the production of, and [[BreakingTheFourthWall even in the dialogue]] of, various shows. For example, the end-of-episode previews during the early part of ''Anime/NeonGenesisEvangelion'' frequently promise "more fanservice."

While the specific term "fanservice" arose from the {{Anime}} community, the concept of adding a little titillation to a work is far, far older. When nudity or sexual content is an expected part of a work, it's not [=fanservice=]; it's only when the nudity or sex is thrown in "just because" that fanservice becomes a part of the narrative. For example, nudity in a pornographic movie would not qualify, while Creator/SharonStone's infamous "beaver shot" in Creator/PaulVerhoeven's ''Film/BasicInstinct'' would. Real fanservice is seldom explicit or graphic -- that is the territory of pornography. Instead it is primarily there to "add a little extra" by teasing and titillating the audience.

Some shows may have [[MsFanservice designated fanservice characters]]; characters who, even if they are main characters and have a role beyond fanservice, can always be found in a fanservice situation. Some shows have characters for [[MsFanservice both male]] and [[MrFanservice female fanservice.]] Exactly how much fanservice makes its way into a series can depend on what channel a show is broadcast on, but with the advent of series on DVD, this can be subverted with liberal application of CensorSteam.

While some fanservice can increase the appeal of a show, too much fanservice can become very distracting and in some cases, [[FetishRetardant put viewers off completely]], [[SelectiveSquick especially if the fanservice is directed towards the opposite sex]]. However, [[SexSells since fanservice can lure in viewers so easily]], fanservice has become a common trend in anime, to the point where it is ''incredibly'' difficult to find an anime without any fanservice. At the other end of the spectrum, CrossingTheLineTwice hard it may be, can also occur at some point thus using the fanservice for the advancement of the plot itself. ''{{Franchise/Negima}}'' is a mild example of this, while something like ''Anime/StrikeWitches'' goes further and ''Seikon No Qwaser'' may be '''the''' definite example of the phenomenon.

Very hard to subvert or even {{lampshade hang|ing}} -- the former is [[FanDisservice usually disturbing]] and the latter is...well, just fanservice with a joke attached. You might as well [[VisualPun have the person wearing nothing but a lampshade]].

[[DistaffCounterpart Fanservice of female characters]] is often called "cheesecake"; [[SpearCounterpart fanservice of male characters]] is often called "beefcake". HoYay fanservice directed at the LGBTFanbase or YaoiFangirl also exists in quite a lot of media (within the VisualKei subgenre of music, for example, "fanservice" and HoYay are almost synonymous due to bands being almost AlwaysMale, and an above usual population of bisexuals early on followed up by the recognition of the YaoiFangirl as one of the primary audiences)

"Fanservice" is sometimes used in a more general way, referring simply to any crowd-pleaser thrown in just because. When this is something non-sexual, like needlessly flashy attacks in a HumongousMecha show, long guitar/bass/drum solos in a concert, or [[ContinuityCavalcade throwing in lots of obscure continuity references]] in a long-running work, it's PanderingToTheBase. [[RuleOfSexy Sexy fanservice is considered the default form, because it is everywhere, and it's easy to add to any kind of show]].

Fan service before the 1990's possibly hit harder with viewers than it does today. Before [[TheInternetIsForPorn the Internet made porn accessible]] to the masses a little fan service would eke out more ticket or item sales. It still has that effect today, but not to the same level.

SexIsInteresting is what happens when a writer tries to rationalize this in terms of narrative craft. Attempts to increase the overall amount of sexual content in a series fall under HotterAndSexier; a similar process but for more violent content is BloodierAndGorier. Contrast DarkerAndEdgier.

Not to be confused with FanFlattering.
