->''"Whether you're a coke dealer, a thief, an arms dealer, or a spy, you need someone to clean your money, which makes a good money launderer the closest thing you can get to a Yellow Pages for criminals."''
-->-- ''Series/BurnNotice''

This is the person who always seems to have the dirt on everybody. The person who runs an information-gathering system, with a network of informers.

The Knowledge Broker has a web of contacts stretching into various organizations, industries, and government agencies, and always seems to know what's going on. Sometimes the Knowledge Broker seem nearly omniscient. He/she always seems to have just the right tidbit of information for whoever is willing to pay their price. For the most part, he remains impartial despite his vast influence, and most people know to stay on his good (or at least indifferent) side.

This is a person who is not mysterious (Compare MysteriousInformant). Everybody knows that when you want information, you go talk to this person. Usually of dubious morality. Often your innocent hero has a [[TheLancer buddy]] who grew up on the wrong side of the tracks, and knows that they ought to start by talking to "Big Eddie" or whoever, cause he always "knows anything that goes down."

Sometimes the source of information is more upscale in appearance, in which case they are probably also TheBarnum. They usually want something from the hero before they hand out the information (unless they owe the Hero a favor, or have a crush on him). Often they'll want nothing more than cash, but sometimes they want the Hero to run an [[FetchQuest errand]] for them. Or they may trade information for information. If there is romantic subtext, she might ask the Hero to be her escort somewhere -- always a good choice for drama when the hero is looking for information about the kidnapping of his [[LoveInterests love interest]]. Obviously saving his true love justifies cheating on his true love -- or does it?

Many times this character is relegated to a position as a [[CharactersAsDevice Plot Device]]. When the Knowledge Broker is given CharacterDevelopment, expect him to have [[FreudianExcuse a traumatizing past]] and/or an old relationship with one of the protagonists. When acting as a contact for the heroes, expect the Knowledge Broker to supply the catalyst to propel the story forward. If the heroes get stuck, expect him to suddenly come up with a new lead. If he's mostly in it for the money, expect either a FaceHeelTurn or a HeelFaceRevolvingDoor that may one day make [[YourHeadASplode someone put a gun to his head]]. If he's less-than-impartial towards the main character, expect him to deny payment, with an excuse like [[IWasJustPassingThrough "I owed you a favor anyway."]] Likely to DefaultToGood (if only because the good side winning would keep them in business); rarely, if ever, is this character working strictly for the antagonist.

If the contact is a recurring character and the Knowledge Broker and the protagonist are different genders ([[HoYay or not]]), [[BetterAsFriends expect]] [[LovesMeNot romantic]] [[SheIsNotMyGirlfriend subtext]].

RealLife information brokers tend to be consultants who work in market research, though there are exceptions.

[[folder: Anime and Manga]]
* The Daily Days, a newspaper from ''LightNovel/{{Baccano}}''
* Big Ear, (because he heard about ''everything'', you know), from ''Anime/TheBigO''. You know, the one with the glasses...
* Ginko from ''LightNovel/KureNai'', for the romantic subtext version. Also Shinkurou's UnluckyChildhoodFriend.
* Nabiki Tendo of ''Manga/RanmaOneHalf''.
* Fuuchoin Kazuki from ''Manga/GetBackers'' theoretically does this for a living, although he's more often seen [[RazorFloss kicking ass]].
* Haruo Nijima from ''Manga/KenichiTheMightiestDisciple'' is a partial case of this. Though he has incredibly skills in analyzing enemies and information gathering in general, he acquires all his intelligence for the sole purpose of furthering his own goals of power.
* Information brokers are one of the most lucrative jobs people can have in the AfterTheEnd setting of ''[[Anime/AfterWarGundamX Gundam X]]''. The second episode has a broker [[TemptingFate boasting about how they're so much smarter than those idiot mobile suit pilots]]. [[KarmicDeath Then he's vaporized by the GX's Satellite Cannon]].
** Speaking of ''Franchise/{{Gundam}}'', ''[[Manga/MobileSuitGundamSEEDAstray Gundam SEED Astray]]'' has the recurring antagonist Kenav Luchini.
* The man [[LastNameBasis known only as Yamada]] in all incarnations of ''Anime/MaiHime'' where he appears.
* Hiruma of ''Manga/{{Eyeshield 21}}''. Like Nijima he uses it for his own gains and specializes in blackmail with it.
* Rufus Barma in ''Manga/PandoraHearts''.
* A [[TimeSkip series]] of [[NoNameGiven unnamed women]] in ''Anime/{{Mnemosyne}}'', who [[TrademarkFavoriteFood drink Grasshoppers]] and take sex as payment (yeah, it's that kind of show).
* Izaya Orihara from ''{{LightNovel/Durarara}}'', though it's hard to tell whether he's [[OnlyInItForTheMoney doing it for the money]] or simply because [[ItAmusedMe It Amuses Him]]. Considering his intelligence and [[{{Jerkass}} his]] [[ManipulativeBastard personality]], it's probably the latter with the former as a perk.
* [[{{Meganekko}} Becky]] [[MiserAdvisor Farrah]] from ''Manga/GunsmithCats''.
* ''Manga/BlackButler'' has the Undertaker. He's just in it for the laughs.
* ''Anime/GunXSword'' has [=Carmen99=].
* [[spoiler: Madeleine]] in the manga of ''Manga/HonooNoAlpenRose''.
* Sonica of ''Manga/MagicalRecordLyricalNanohaForce'', who is a genuine palm reader who could read a person's memories and biological data by touching her target. This, combined with her personality and the fact that everyone in the underworld goes to her when they need to interrogate someone, means she's got the dirt on everybody. Like most Knowledge Brokers, she's in it for the money so the price of her info is always very steep, and she has plenty of blackmail material for those unwilling to pay.
* Information Brokers in general in ''LightNovel/SwordArtOnline'', especially Argo. Argo once sold a piece of information, then sold the information about her selling that information, then offered to sell even that information of the sale of information about the information the original buyer of the actual information. Quite the knowledgeable knowledge broker.
* Itori from ''Manga/TokyoGhoul''. She runs an extensive information network from her bar, ''[[Music/TheBeatles Helter]] [[UsefulNotes/CharlesManson Skelter]]'', and also handles any sort of legal documentation that other ghouls might need.

[[folder: Comic Books]]
* Examples in the Franchise/TheDCU
** [[Franchise/{{Batman}} Oracle]] usually fills this role for Batman.
** The Calculator from Franchise/TheDCU was a goofy Silver Age villain with a giant pocket calculator on his chest and vague AwesomenessByAnalysis powers - until ''ComicBook/IdentityCrisis'' revamped him into Oracle's EvilCounterpart, a knowledge broker for supervillains. In Videogame/DCUniverseOnline, the two serve the role as MissionControl for heroes and villains respectively using their know-how.
** A similar role (information broker to the villains) was played by the Monitor during the run-up to ComicBook/CrisisOnInfiniteEarths. His role in the actual ''Crisis'' is quite different.
** [[DependingOnTheWriter In some instances]], Jason Todd as the [[TheUnfettered Red]] [[AntiVillain Hood]] has played this role, bringing valuable information to heroes. And, occasionally, villains. For his own ends, or to ensure they end up getting themselves killed. If it came up more often he'd be a MagnificentBastard.
** The Penguin functions as an information broker for Gotham's underworld, and sometimes to Batman, with a little arms dealing thrown in for good measure.
* Information is just another commodity in the world of ''ComicBook/{{Finder}}'', and Lynne Grosvenor is implied to be one of the best infotraders in Anvard. Within an hour of his sisters' mugging, he's recovered their belongings and tipped off the police (if not something worse, considering how [[DisproportionateRetribution protective]] he is [[BerserkButton of Marcie]]).
* Nomad, from Creator/MarvelComics, confronts the 'Favor Broker', who is also a BigBad, multiple times through his title series. The Broker claims not to like the position he is stuck in but is too piled up with favors to ever quit.
* The Consultant from ''ComicBook/PS238''.
* In the ''Comicbook/AstroCity'' story, "The Tarnished Angel," Donnelly Ferguson uses his knowledge of the city's underworld to find jobs for the B-rate villains of Kiefer Square. [[spoiler:He arranges for all of them to be hired for a city-wide crime spree planned by fallen hero El Hombre, who plans to kill all the villains and restore his heroic stature.]] Steeljack didn't like associating with him even before all this came to light, but because Ferguson didn't have a record he was one of the very few people he knew with whom he could freely mingle without violating his parole. He never gets what's coming to him, but he's not the same man after the Conquistador incident, either.
* The Harlot functions as this in ''ComicBook/FallOfCthulhu.'' As one of the most powerful entities in the DreamLand, she can provide virtually any form of information; her asking price is generally a piece of the client's body, [[spoiler: though she will occasionally accept pieces of the client's mind -- especially in the case of Raymond Dirk.]]
* Max Normal in early ''ComicBook/JudgeDredd'' comics.
* ''Series/{{Angel}}'' had a creature, Polyphemus, with an encyclopedic knowledge of demonology. There was some romantic subtext between him and Laura, a former watcher.
* The Shingouz in ''ComicBook/{{Valerian}}'' are [[PlanetOfHats an entire race of creatures]] who specialise in spying and information trade. A trio of them often push their servicees on Valerian and Laureline and end up getting them involved into the main plot of the ongoing issue.
* Feetus from ''ComicBook/{{Grimjack}}''. Notable in that he and Grimjack were old war buddies and genuine friends. He plays a more important role in the plot than just a source of information for Grimjack.

* ''Fanfic/ChildOfTheStorm'' has Ivan Petrovich, a former Red Room Agent who served as a ParentalSubstitute to Natasha and joined her in defecting. Natasha inwardly considers him to be one of the best intel analysts on the planet and in chapter 67, both [[spoiler: the Red Room and HYDRA make a play for him. Both are foiled by the Winter Soldier, who is nominally working for HYDRA, and manages to help Petrovich fake his death.]]
* ''FanFic/DungeonKeeperAmi'' features Keeper Midori, who fits this Trope to a T. She keeps close tabs on all the warring factions in the story, often popping up at opportune moments- such as lulls in the fighting -to offer information on their enemies, at a price.
* ''Fanfic/FutariWaPrettyCureBlueMoon'' has Omemi Emiru, a different sort of an AlphaBitch who uses this (something she calls a "talent" for coming upon other people's information) to keep her classmates in line. [[spoiler:Her Etherium powers reflect this, as she uses her illusion abilities to, in a sense, construct what others see of reality, made more convincing by what she's found out about them.]]
* In ''[[http://www.fanfiction.net/s/8271684/1/Next-On Next On]]'', [[Music/{{Vocaloid}} Gakupo]] is one.
* Kunsel in ''VideoGame/CrisisCore'' was a well informed and vaguely gossipy Mr. Exposition. ''FanFic/TheFifthAct'' upgrades him having a vast information network, being everyone's go to guy for information and in the Omakes, being better informed than the Turks.
* In the ''Literature/{{Discworld}}'' fics of Creator/AAPessimal, Conina's Barbarian Hairdressing Salon is a hub of information exchange which stands outside the usual network of Guilds. Conina Cohensdaughter-Harebut is a Thief and barbarian heroine who fulfilled her vocation to be a Hairdresser. And everyone needs a hairdo. And ''everyone'' - Thief, Assassin, Heroine, Watchwoman, Seamstress, Teacher - talks to their hairdresser. Who if she is so inclined may pass interesting information back.

* The Brain in the film noir send up ''Film/{{Brick}}'' provides Brendan with intel on the situation at the school.
* ''Franchise/TheMatrix'':
** The Merovingian from the sequels. "I am a trafficker of information, I know everything I can."
** Neo also qualifies, before his RedPillBluePill decision in the first minutes of the original film.
* In ''Film/OsmosisJones'', this was the function of the Flu shot. Kinda justified, if by a long shot, by those who know a bit of biology.
* In ''Film/{{Heat}}'' (1995) Robert [=DeNiro's=] character consults such a figure for intelligence on potential heists and police opponents. When [=DeNiro=] asks him where he gets this stuff he replies that it just comes to him through the air (his house is festooned with antennae and located on a hill above Los Angeles).
* Louis, the French guy from ''Film/{{Munich}}'', along with the rest of his family.
* Skinny Pete from the 2003 remake of ''Film/{{The Italian Job|2003}}'' acts as this for Charlie and his crew when they pull their final heist in L. A.
* From the ''Film/LethalWeapon'' series, Leo Getz. [[CatchPhrase "Whatever you need, Leo Gets".]] (Unfortunately, he tends to '''get''' [[ButtMonkey himself in trouble a lot.]])
* In ''Film/AttackOfTheClones'', there was Dex, the owner and chef of Dex's Diner. Seeing as his place was popular with merchants, smugglers, and other frequent travelers, he often overheard things that no-one else did, and was willing to sell the info. In the movie, Obi-Wan goes to him to find information on the Kamino cloning project.
* ''Film/AIArtificialIntelligence'': Doctor Know... is in the know. And is also an unreliable search engine that charges per-question, but that's besides the point.
* ''Film/XMenApocalypse'': Caliban is a broker and informant on mutant goings-on.
* Mr. Universe for the series ''Series/{{Firefly}}'''s BigDamnMovie ''Film/{{Serenity}}'', the self proclaimed "eyes and ears of the 'verse."
* ''Film/WelcomeToThePunch'' (2013). A criminal seeking to put out some information on the street as TheBait visits a tattoo parlour whose owner gives him the option of releasing the information "old school" (word of mouth) or "new school" (via Facebook and Twitter).

* Billy from the Final Friends series by Christopher Pike always knew where everyone was all the time. No one questions how he knows.
* ''Literature/ASongOfIceAndFire'':
** Varys "The Spider". Having no title or wealth (being referred to as Lord out of courtesy), and being a foreign eunuch, he only managed to survive the overthrow of the Targaryen dynasty because of his usefulness.
** After [[spoiler: Joffrey and Tywin's murders]] Cersei replaces him with Qyburn of the Brave Companions. Suprisingly, Qyburn actually manages to do just as good of a job, if not better than Varys himself, effectively making him a HypercompetentSidekick to Cersei.
** His rival, [[MagnificentBastard Lord Petyr "Littlefinger" Baelish]] (Unlike Varys, he is an actual lord, but his main title is to a crumbling tower house in the ass-end of nowhere; he does later gets the massive castle [[HauntedCastle Harrenhal]] as a reward for his service), can be considered this as well. Turns out that owning several high-end brothels frequented by powerful nobles and merchants has other benefits beyond the obvious.
** Maesters of the Citadel function rather much like this. Their primary loyalty isn't, in reality, to the individuals they serve, but to their ''role and calling'' as Maesters. When push comes to shove, they are contracted advisors with a fairly standardised set of skills and knowledge attached... hired and maintained by lords from their central "guild" in the shape the Citadel of Old Town. The plus-side to this arrangement: fewer PromotedToScapegoat incidents for them as advisors.
* Slughorn from the ''Literature/HarryPotter'' novels was one.
* Chrysalis, the transparent-skinned owner of the Crystal Palace bar in the WildCards universe, uses a telepathic bartender and tiny spy-creatures spawned by a unique Joker to gather information-- along with the traditional bribes and espionage.
* The sheer scale of the ''Franchise/StarWars'' universe dictates a rather absurd number of these. By ''far'' the best, though, is smuggler-in-chief [[Literature/TheThrawnTrilogy Talon Karrde]], whose organization, which took over after Jabba The Hutt's enterprises collapsed with his death, was built on information brokering. He ended up [[DefaultToGood defaulting to the New Republic's side]] [[MistreatmentInducedBetrayal after]] Thrawn had him kidnapped to try and coax the location of a lost fleet out of him. In the HandOfThrawn duology, he took a certain crucial bit of intelligence to Supreme Commander Pellaeon in time for a BigDamnHeroes moment, and his organization sets up between the newly at peace New Republic and Imperial Remnant, making sure information flows freely to both sides so there won't be any nasty secrets. His old mentor knows everything, but withdrew from galactic affairs.
** Around second place or so are the various other important smugglers, and government agents are somewhere around twentieth. Unless they're ''Thrawn's'' agents, that is, or wherever and whatever he gets his intel from.
* Pahvulti, the renegade [[{{Cyborg}} Tech]] [[MachineWorship Priest]] in Simon Spurrier's TabletopGame/{{Warhammer 40000}} Literature/NightLords novel ''Lord of the Night''. He was exceptionally good at his job, becoming the information baron of a hive, due to his mentality of a cad combined with his thought processes being that of a computer.
* AmoralAttorney Kodringer in ''Literature/TheWitcher''
* Charles Augustus Milverton of the ''Literature/SherlockHolmes'' tale that bears his name.
* After refusing to back down from a touchy case and losing her position, [[spoiler: Wolfe]] from the Creator/AndrewVachss Burke books takes on this role, and is apparently the best at it.
* "Done it" Duncan of the Literature/{{Discworld}} acts unwillingly as this, as he claims to have performed every crime that happens in the city, including a SuspiciouslySpecificDenial that can be very useful to the Watch.
** Also, Fred Colon from ''Night Watch'' forward, in a strange way. After being pulled off the streets, he is given an office, where he always keeps a kettle going and a box of free doughnuts. This is a favourite hang-out for ex-cops, old cons and petty criminals, all of whom have an ear to the street and gossip like old washerwomen. Colon hands over the information gathered to Vimes, who gladly pays for the tea and doughnuts in return.
* The Outsiders from Larry Niven's ''Literature/KnownSpace'' stories. Unusually, they don't care about getting the dirt on anybody; their business is in [[{{Precursors}} Slaver-era]] technical knowledge (they sold humans the hyperdrive, giving them a fighting chance in the Man-Kzin Wars) and treasure maps. It's almost impossible to acquire knowledge in these fields that you can sell ''them'', but if you can do it you'll pretty much be set for life.
-->''It was well known that the reactionless drive the Outsiders used was for sale, and that the price was a full trillion stars. Though no individual, and no nation now extant, could afford such a sum, the price was not exorbitant.''
* The [[ExactlyWhatItSaysOnTheTin Remover of Inconvenient Obstacles]] from Creator/TadWilliams's ''Literature/WarOfTheFlowers''.
* The former CIA from ''Literature/SnowCrash'' is a knowledge-brokering company. Among other things it employs camera-laden guys who roam around recording everything, in case it'll come in handy later.
* Gyoko from ''Literature/{{Shogun}}'' seems to know everything, and has a network of courtesans who supply her with information. In a society that values titles and military power, she manages to do much with the use of information only.
* "Papa" Friedlander Bey from the ''[[Literature/MaridAudran Marîd Audran series]]'' deals exclusively in information on a global scale; governments operate, or not, based on the information bought, sold, and traded by him.
* Magician Humphrey from the ''Literature/{{Xanth}}'' series is not ranked as a magician for being born with powerful magic, but rather for his ability to find information. He can answer any question, but because so many people have questions, they have to get past three obstacles to get to him and work for him for a year or provide some other kind of significant service for him in return. This way, only ''serious'' Questions come to him to keep things sane.
* This is the [[PlanetOfHats Hat]] of the Agletsch, a ProudMerchantRace in the ''Literature/StarCarrier'' series. Any given inhabited star system has resources aplenty to manufacture goods, so instead the Agletsch buy and sell everything from intelligence to schematics and technical data, and even art.
* In Lawrence Block's Literature/MatthewScudder series, Danny Boy Bell, an albino black man, performs this role. A website providing information about the book series, [[http://pooganspub.com/ Poogan's Pub]], is named after one of the spots Bell frequents.
* In ''Literature/TanteiTeamKZJikenNote'', [[TheSocialExpert Kuroki's epithet]] doesn't only refer to his social skills, but also refers to his large social network which allows him to obtain information about ''everyone'' in the neighbourhood. Probably because this work is aimed at children, unlike most examples of this trope he's a recurring member of TheTeam and is seen to be morally upright.
* In ''Literature/TheIronTeeth'' web serial, the mysterious and beautiful woman Luphera aids Blacknail the hobgoblin by trading him information. She also appears to sell information, among other things.
* ''Literature/{{Edgedancer}}'' (a novella of ''Literature/TheStormlightArchive''): Nigh-everyone in Yeddaw buys and sells information, as in their country, knowledge is a currency as good as - and sometimes better than - physical money.

[[folder: Live Action TV]]
* [[TheMadHatter Hatter]] from the miniseries ''Series/{{Alice|2009}}''. Ratty describes him to Alice as "a man who knows," and he seems to be connected with everybody - [[TheEmpire the Hearts]] and [[LaResistance the Resistance]]. His {{street smart}}s and knowledge of Wonderland are a help, and when he and Alice have run out of plans and resources, he lists an obscure woman he knows through about [[Series/SixDegreesOfKevinBacon eight different people]] and suggests talking to her, although he admits it's rather a long shot.
* ''Series/GameOfThrones'': This is Varys' job as Master of Whisperers, and he's terrifyingly good at it. If for whatever reason a character does not go to Varys, they go to Littlefinger.
* "Ice Pick" from ''Series/MagnumPI''. Definitely of the "dubious morality" sort.
* Arvin Sloane from ''Series/{{Alias}}'' fulfilled the role for a season, when he wasn't being the BigBad.
* That black stereotype ''Series/StarskyAndHutch'' were always going to for the 'word on the street', "Huggy Bear".
* Parodied in the shape of Johnny the Snitch on ''Series/PoliceSquad!'', the shoeshine guy who could give you information on absolutely ''everything'' -- at a price -- whether you're a firefighter wanting help tackling a blaze, a surgeon needing advice on how to perform an operation, or [[http://www.poetv.com/video.php?vid=11645 just Dick Clark asking about musical trends (and youth cream)]]...
* If Sam Axe isn't performing this function in ''Series/BurnNotice'', he knows someone who does. Another frequent source of information is Barry, the money launderer (currently the subject of the page quote), who knows at least something about everything slightly shady that happens in Miami, as all the crooks in South Florida seem to use him to clean their gains.
* Guerrero, on ''Series/HumanTarget''. How did he get that photo? "Dude, you don't want to know."
* Fin Tutuola on ''Series/LawAndOrderSpecialVictimsUnit'':
-->'''Munch:''' Fin bolted a few hours ago, didn't say where. That usually means a covert meeting with one of his operatives in the Drug Netherworld.
** Munch himself, being Creator/RichardBelzer, has contacts he can call on for anything related to spying, black ops, national security, and three-letter agencies.
* The final two episodes of season one of ''Series/NCISLosAngeles'' centered on a Knowledge Broker who had files on hundreds of people and sold that information to whoever paid more.
** There's also Hetty Lange, who's firmly on the side of the good guys--she seems to have limitless knowledge of ''everything'' that goes on not just in her unit, but pretty much all over the planet. Hetty has a massive database of contacts and connections from her days in the Cold War, and is fluent in at least eleven languages. She even lampshades the role in one episode when she's accused of being TheChessmaster; Hetty demurs and explains that she doesn't see individual pieces--she sees, and moves, the ''whole board.''
* Mycroft on ''Series/{{Sherlock}}''. He ''is'' the British Government.
* Philip from ''Series/KamenRiderDouble'' has all of Earth's knowledge in his head.
* Limehouse from ''Series/{{Justified}}'' has an extensive network of informants throughout Harlan County and the neighboring areas. If you are a client of his unofficial bank, he will share the information if you ask nicely. He is a leader of a black community in the mountains of Kentucky and his community survived since the Civil War by always knowing what its enemies and allies were up to and where the next threat was coming from.
* JK from ''Series/KamenRiderFourze'' has information on every student in the school and it's his ''first-year'' in Amanogawa High.
* ''Series/StarTrekDeepSpaceNine'': Garak, Odo and Quark all play this role. Garak's comes from the intelligence world and he has connections everywhere and in every facet of society. Odo's tend to be police, security and politically based and Quark's tend to be economic and black market.
* Trick from ''Series/LostGirl''. Part of it comes from being the owner of a bar that's one of the few places open to both Light and Dark Fae, part of it from [[spoiler: having once been the Blood King]].
* Dorium Maldovar, owner of the Maldovarium, who knows - among MANY other things - [[spoiler: what is The Question]] in ''Series/DoctorWho''.
* [[StealthPun Saul Goodman]] from ''Series/BreakingBad'' is a well-networked example of this role, of the "mostly in it for the money" type. Whether you need help cleaning up a crime scene after [[spoiler: your girlfriend dies of overdose]], need an expert conman [[spoiler: to impersonate a water inspector]], or simply need a buyer for your large quantities of illicit drugs, Saul either knows who can get the job done, or he [[KnowsAGuyWhoKnowsAGuy knows who knows them]]. [[KitschyLocalCommercial Better call Saul]]!
* The mysterious hacker group Everyone from ''Series/{{Elementary}}'' serves as this; while they initially serve as antagonists in an episode, they later befriend Sherlock and Joan, providing helpful information on cases in exchange for odd favors. [[spoiler: In a particularly [[CrowningMomentOfAwesome awesome moment]], Joan calls on a few members of Everyone to serve as eyewitnesses (via Skype-like video services) to a villain threatening her and [[EngineeredPublicConfession describing his latest scheme.]]]]
* Antique book dealer Felix Muholland fills this role in ''Series/{{Banacek}}''; tracking down whatever esoteric piece of information Banacek needs to crack a particular. Interestingly, he is the only character who ever refers to Banacek by his first name.
* The villainous [[FatBastard Dale "the Whale" Biederbeck]] of ''Series/{{Monk}}'' is one of these (it helps that he's also [[Fiction500 insanely rich]]). In his debut episode, it's revealed that he has dirt on everyone from politicians to professional baseball coaches, and can make them obey him with a single phone call; later, he somehow manages to learn about some shameful parts of Natalie's past within a day or two of her meeting him. In a later episode, he forms an EnemyMine pact with Monk by offering information on Trudy's death that even the cops never discovered in exchange for Monk's clearing him of a murder. What makes this particularly impressive is that Dale weighs in at 800 pounds, and thus runs his information empire from a specially-made bed.

[[folder: Tabletop Games]]
* Having good contacts is key to survival in ''TabletopGame/{{Shadowrun}}''. If you don't wanna die or get arrested by Lone Star, that is. They're even ranked: Level 1 contacts are acquaintances, Level 2 are slightly more trustworthy because they know you and have worked with you in the past, and Level 3 is an old friend who will bend over backwards to help you.
** The rankings are changed in Fifth Edition - now there are two categories, Loyalty and Connections. Level 1 Loyalty is someone who you do business with that doesn't really care about you; Level 6 is someone who will dive under a bus for you. Level 1 Connections... aren't (a homeless guy on the street); Level 12 Connections are on the top of the heap in terms of who they know and what they can do (a Great Dragon).
* The entire Nosferatu clan serve this function in ''TabletopGame/VampireTheMasquerade'' and its [[VampireTheMasqueradeBloodlines PC counterpart]]. Being vampires that live BeneathTheEarth and have the ability to turn invisible, they have considerable influence- allowing them to charge high prices for information and make life unbearable for unwanted customers.
** In ''TabletopGame/VampireTheRequiem'', this role belongs to the Mekhet clan, who have the added advantage of looking normal, and being able to acquire information directly through supernatural means (such as MindReading, {{Psychometry}}, or AstralProjection).
** Also, every mage, to a certain extent, though the Mysterium are the ones with the main focus on it. One {{Sourcebook}} provides detailed information on how their "knowledge economy" works.
* In ''TabletopGame/WerewolfTheApocalypse'', the Corax wereravens (and to a lesser extent, the Bone Gnawer Garou) serve as this to other supernatural beings.
* From ''TabletopGame/ForgottenRealms'', we have [[NamesToRunAwayFromReallyFast The Pillar of Skulls,]] a hideous landmark upon [[FireAndBrimstoneHell Baator]]. Composed of the heads of various beings, it can access their knowledge to answer many questions... but it won't be free. The Pillar will ask for sacrifice to be made as payment, but sometimes it will take valuable information it has not already known as well. Notably, the Pillar is not omniscient, asking a question it doesn't know the answer to will not levy any payment.
* TabletopGame/{{Warhammer 40000}} has the Keeper of Secrets, the Greater Daemon of Slaanesh that knows every one of your dirty little secrets. It actively uses this information in combat to hamper you, ranging from bribing you with your heart's desires to revealing something that shatters it's victim's minds.

* Johnnypateenmike in ''The Cripple of Inishmaan'' by Creator/MartinMcDonagh-- his "choice pieces of information" range from YetAnotherBabyPanda to [[GossipyHens everyone else's secrets]], and he barters them for food and other products from local merchants in their small town.

[[folder: Video Games]]
* ''Franchise/MassEffect'' has the Shadow Broker, the completely unknown head of a vast Information Brokering Empire. Even the highest ranking members of the organization communicate with their boss only through audio-only communications channels, in which the Shadow Broker uses a computer generated voice.
** The Illusive Man at the head of Cerberus is also in the same business, but he doesn't use it for profit but to always be ahead of his enemies and to use the information he has as bribes or for blackmail. He doesn't sell information, but only shares it to make other people depending on him.
** In the second game, Liara starts her own business on Illium, but for her the profits are mostly to fund her own investigations into the identity and location of the Shadow Broker, who tried to find the dead body of Shepard and sell it to the Collectors and kidnapped her partner when she gave the body to Cerberus first. Her real goal is to kill the Shadow Broker and rescue Feron. [[TookALevelInBadass Not bad for the socially awkward archeologist from the first game.]]
** The ''Lair of the Shadow Broker'' DLC takes Liara and Shepard to the secret base of the same. [[spoiler:Where it turns out that the current person behind the desk is a huge gorilla-like alien who was kept as a slave and pet by the last Shadow Broker. After he killed his master in his own private chambers, he simply sat down at his computer and continued business as usual. And after he is killed in battle and the computers restart, Liara does the very same thing, instantly becoming one of the 10 or so most powerful people in the entire galaxy.]]
* ''VideoGame/DragonQuestVIII'' had a guy like this named Brains.
* Jules in ''VideoGame/FinalFantasyXII''.
** Due to the way Archadian high society works, everyone in Archades is a Knowledge Broker to one degree or another.
* The Oracle in ''VideoGame/DeusEx'' is an AI [[InstantAIJustAddWater born in cyberspace from the sheer information in it]], who trades what he knows for information he does not have (this doesn't have to be of any value, a "joke you heard recently" and your breakfast are both things he requests in exchange for information). However the Oracle only appears at three points in the game, all in emails that are entirely optional to read, and everything we know about him is WordOfGod.
** This is a reference to the [[http://en.wikipedia.org/wiki/Usenet_oracle Usenet Oracle]].
* In ''VideoGame/StarControlII'', this is the [[PlanetOfHats hat]] of the Melnorme, who accept "bio-data" from you in exchange for galactic history, current events, and technological specifications. [[ProudMerchantRace They also sell starship fuel.]]
** They also refuse to take anything for free. When they met the Slylandro, who were completely willing to give up their knowledge and history for free, they couldn't accept that and figured out a way to give them something they could use. [[NiceJobBreakingItHero Problem was that inadvertently cause them to get access to the Slylandro probes which]] [[AIIsACrapshoot wound up being badly programmed and]] [[GoddamnedBats attacking everything in sight.]]
* Everyone you talk to in ''VideoGame/CityOfHeroes''. Seriously, how does Joe Shmoe know which warehouse the Trolls are selling firearms out of? Granted, many of your contacts have some relation to law enforcement or the criminal underworld, but it gets quite silly after a while.
** Becomes ''ridiculously'' literal in Praetoria, where the game's primary currency is labelled ''Information''. This hat will cost 30 informations sir.
* Jay the Unseen in ''VideoGame/TalesOfLegendia''.
* Kage the Florist (or just The Florist) in the ''Videogame/{{Yakuza}}'' games.
* Wiseman from the ''VideoGame/DotHackR1Games'' had this as his initial occupation, before joining the team for real.
* In [[http://www.youtube.com/watch?v=P5DuwoHpEa4 I Will: The Story of London]] for the Pioneer Laseractive, the man to see was Mr. Pound AKA "Antenna", who runs a Britain-wide information network. He's easily recognised as he's the only person in the entire game who carries two umbrellas in one hand.
* In ''VideoGame/YandereSimulator'', Info-chan. This mysterious individual is Yandere-chan's ally (technically; Info-chan knows her intents, but really doesn't care one way or another) and can be used to gain information on targets in exchange for ''{{panty shot}}s''.
* In ''[[VideoGame/WingCommander Privateer]]'' Roman Lynch provides information to the protagonist to aid his quest in finding out about the mysterious artifact he's acquired, at the expense of performing missions for him.
* The Riddler is depicted this way in the ''VideoGame/BatmanArkhamSeries''.
* This seems to be the in-story role of [[BadassInANiceSuit Sai]] in VideoGame/AkatsukiBlitzkampf. He is said to be a person who, through illegal means, gathers all the information in the world. [[spoiler: Though it looks like he might actually be an undercover agent for the [[http://en.wikipedia.org/wiki/Secret_Intelligence_Service MI6]].]]
* Oskan in ''VideoGame/StyxMasterOfShadows'' is a blind old crook wanted by the Akenash human government. He has many connections tapped into the criminal underworld of Akenash and mainly serves as the contract provider for Styx, offering Styx directions and information to help him reach his goals in exchange for Styx stealing and killing for him.
* Varric does this when not writing or adventuring in ''VideoGame/DragonAgeII''. This is all done in place of what should in theory be his actual job, namely running a business, which is in fact registered to a totally fictitious cousin.
-->'''Varric:''' It means coins flow when I talk ''and'' when I shut up.
* The rumormongers in ''VideoGame/{{Persona 2}}'' inform you of, among other things, shops that secretly sell weapons/armor and those shop's prices, or of demons existing or knowing specific skills. For a fee, Detective Todoroki spreads those rumors and makes them come true.

* Redd White from ''PhoenixWrightAceAttorney''. His company, Bluecorp, was an information-gathering corporation that specialized in obtaining blackmail material concerning big-name individuals such as celebrities, politicians as well as high-ranked people on the judicial system, effectively making White [[ScrewTheRulesIHaveConnections a man above the law]].
** [[spoiler: Until Phoenix got him guilty for Mia's murder, that is.]]

* [[http://amazingplasmaman.com/comics/62 Ace Tanager]] from ''Webcomic/TheIncredibleAndAweInspiringSerialAdventureOfTheAmazingPlasmaMan'' holds a wealth of information about the citizens of Meridian City, which he gladly shares with Plasma-Man in exchange for patronage of his lounge.
* Landon from ''Webcomic/ThisIsNotFiction'' is introduced as one, being the self-titled "Godfather of Highschool".
* ''Webcomic/PlanescapeSurvivalGuide'' had the [[http://planescapecomic.com/7.html "info imp"]], not that he was particularly helpful.
* ''Webcomic/AMiracleOfScience'': Benjamin spends four pages talking to a broker named [[http://project-apollo.net/mos/mos044.html Taro]], who gives him a lead by consulting his OmniscientDatabase of black-market programmers to identify the author of code on a chip. He trades for this info with photos he took aboard a Martian ship -- the Martians have just rejoined the interplanetary scene, and Ben has a closer relationship with them than most. He and Taro evidently enjoy a friendly working relationship.
* Lisa from ''Webcomic/{{Paranatural}}'' runs the school store at her middle school and acts as an information broker for gossip.

* Luke Anatoray, from v2 of ''Roleplay/OpenBlue''.
* Shadow of ''Literature/SuperStories'' makes her living this way. Whether she has a supernatural ability for getting information or is just very good at her job has not been answered.
* Jonathan Patches of ''Roleplay/TheGunganCouncil'' can get information on ''anything'' as well as make sure no one gets certain information one doesn't want to let out.
* Ash, the RealMoneyTrade guy from ''Franchise/{{Noob}}'', seems to be a downplayed case. There is no explicit mention of any kind of extensive network, but any knowledge he ''does'' get his hands on is merchandise like any other to him. That aspect of his activities doesn't become relevant to the plot until late Season 5 of the webseries and the movies.

* Geezy the Pegelount is one of these in the WretchedHive of Tortuna in ''[[WesternAnimation/AdventuresOfTheGalaxyRangers Galaxy Rangers]]''. A later episode reveals that his cousin is one of Her Majesty's victims (explaining why he's no fan of hers). {{Fanon}} also suspects Doc was one of these before being "reluctantly" recruited into the Rangers.
* Mr. Cairo from ''WesternAnimation/{{Phantom 2040}}''. He only values knowledge and no amount of currency, which is probably why he hasn't told the BigBad who The Phantom is despite the hefty reward. He never appears in person, only communicating with his customers through holograms. [[spoiler: It turns out he's not a person at all, but rather a sentient computer program.]]
* In the ''WesternAnimation/LooneyToons'' short "China Jones", Daffy seeks info from one called Limey Louie. Unfortunately, this is a ruse by Louie himself, who bears a grudge against Daffy for sending him to jail.
