15The situation where a work of fiction which features a RealLife product as a {{Prop}} has a significant effect on whether customers want to have that product. The effect can be negative or positive: it can increase demand or reduce it. This trope can also apply to goods and services (a film about a honky-tonk bar might increase enrollment in line dancing lessons, for example).
16
17The effects of this trope are usually temporary; only in UrbanLegends does a work "kill" a product for all time. In fact, demand almost always increases for a product featured in a work, even when [[NoSuchThingAsBadPublicity the product is portrayed negatively]]; advertisers call this the "[[WesternAnimation/TheSimpsons Homer Simpson]] effect". Demand can also increase or decrease for unrelated reasons, so beware of assuming that correlation means causation.
18
19The {{Trope Namer|s}} is the red Swingline stapler prominently featured in ''Film/OfficeSpace''. Swingline didn't make full-size red staplers; the one in the film was a black stapler painted red. Then [[LifeImitatesArt life would imitate art]], as people demanded a red version, and [[{{Defictionalization}} they got one]]. Outside the U.S., [[IHaveManyNames this trope has other names, too]]. Cooking shows are particularly prone to this: Brits usually refer to this as the "Delia Effect", after high-profile CookingShow host Creator/DeliaSmith, to the point that her publishers would let the shops know in advance what she was going to recommend. Australia calls it the "Masterchef Effect" for similar reasons.
20
21{{Defictionalization}} is when the fictional product comes into existence because of this trope, largely as tie-in merchandise to the show that spawned it. Creators who are trying to evoke this reaction may be getting money from sponsors [[ProductPlacement to feature their products]] or they might be [[MerchandiseDriven producing the products themselves]].
22
23If a work increases demand for another work, that's the ColbertBump; if it changes demand for a song, that's RevivalByCommercialization. If it increases demand for a pet, that's PetFadStarter. If a name becomes popular because of a work, that's BabyNameTrendStarter. If it increases tourism for a certain location, that is TouristBump. TrendKiller overlaps with negative instances of this trope. See also AluminumChristmasTrees, where something real but outlandish is shown in fiction and people think it must be fictional.

34[[folder:Advertising]]
35* In the '90s, Gap made [[https://www.youtube.com/watch?v=XJ735krOiPo a commercial for khaki pants]] showing people dancing the lindy hop. The commercial did a better job of making people all over the USA start signing up for lindy hop lessons than making them buy the pants.
36* A rather sweet old advert for the Yellow Pages featured an old man looking for a book called "Fly Fishing" by J. R. Hartley. The ad proved so popular that the book was later [[http://www.amazon.co.uk/Fly-Fishing-Memories-Angling-Days/dp/B000KP322S/ref=sr_1_2?ie=UTF8&qid=1417535491&sr=8-2&keywords=fly+fishing+by+jr+hartley written and published.]]
37* A 2002 ad for BT communications featured a [[https://www.youtube.com/watch?v=Ks_h4X9DhYI rather special telephone.]] The public went crazy for it.
38* The grim nature of ''Anime/PuellaMagiMadokaMagica'' was rather [[MoodWhiplash offset]] by some of the commercials that appeared during the breaks. [[https://www.youtube.com/watch?v=PD-_oLjmCGY The Morning Rescue advert]], in particular, caught the eyes of fansubbers, to the extent that one group began editing it into episodes where it had not originally appeared. Demand for the drink shot up due to curious Westerners who, having witnessed the MemeticMutation in progress, wanted to try it for themselves; as a result, J-List began stocking Morning Rescue in their online store.
39* Some Target advertisements had people wearing clothes with the Target logo on them; demand was such that Target wound up making them for real.
40* Volkswagen had a print ad for the Polo which showed a car with every part a different color (red doors, yellow hood, blue roof, etc.). Enough people requested a car like that that VW made the Polo Harlekin.
41* [[https://www.youtube.com/watch?v=mJipJwDPJ-g A commercial]] from the Dutch insurance company OHRA (in which a mother and her daughter try to pick up their purple inflatable crocodile at the lost and found of a swimming pool, but are met with severe bureaucracy) led to a huge demand for purple inflatable crocodiles, which until then only came in the color green. It also led to the phrase "purple crocodile" becoming a metaphor for {{obstructive bureaucra|t}}cy.
42* The US National Dairy Council once put out a series of advertisements showing cows sabotaging the marketing campaigns of a company called Big Fizz Soda, replacing their ads with ads for milk. Nobody involved with the campaign thought to actually trademark the name Big Fizz Soda, so a soda company did so and promptly started selling their products under that name. Big Fizz Soda can still be found in drugstores and independent supermarkets.
43* Commercials for Windex would sometimes feature angry crows who would use "smear sticks" to dirty windows again. Smear sticks aren't real (or aren't called that, in any case), but home goods stores will occasionally get people asking for them.
44* Australian automotive accessories retailer Repco once had an ad that featured a motor enthusiast replacing his doorbell with one that made the sound of a revving engine (much to his girlfriend's disgust). They received so many inquiries about this, they started stocking a bell that made this noise.
45* A 2014 ad for UK supermarket Asda featured three identical garden gnomes fishing in a pond, staring in shock when a gnome in a mankini floats past on a lilo. This was to make some kind of point about the conventional gnomes representing "ordinary" supermarkets or something, but due to demand, they started selling replicas of the gnome. Mankini-gnomes already existed (one appears in ''WesternAnimation/GnomeoAndJuliet''), but not this particular model.
46* The ''Advertising/CompareTheMeerkat'' advertising campaign (for an insurance comparison site) increased demand for meerkats as pets in the UK. Meerkats do not make good pets though.
47* In 2001 a [[https://www.youtube.com/watch?v=YQo95oI4nXY commercial]] for Audi featured a [[https://en.m.wikipedia.org/wiki/Wackel-Elvis Wackel-Elvis,]] a dashboard bobble figure of Elvis Presley which performs by swinging his hips. The figure was only a prototype for said commercial. But that bobble figure lead to such a high demand that Audi had them manufactured.

50[[folder:Anime & Manga]]
51* ''Manga/TheDropsOfGod'' is an incredibly powerful example of this trope. Thanks to the miracle of Internet wine ordering, thousands of Japanese people are treated to a charismatic character's opinion of a specific wine on his quest to find seven specific varieties, and can then go and order those very wines and taste them for themselves. [[http://www.guardian.co.uk/lifeandstyle/2010/sep/22/french-winemaker-vintage-manga-cartoon This has caused quite a stir in the world's wine industries.]]
52* ''Manga/KOn'' did this with the characters' instruments, particularly Fender. For instance, Mio's Fender Jazz Bass is now popularly demanded in real life -- even though the original is left-handed and the defictionalized ones are mostly stringed for right-handed use. The one main exception is Gibson guitars, mostly because they're hideously expensive (the Les Paul that Yui plays ''starts'' at around $2500 USD), although Les Paul ''clones'' are popping up marketed with the show's imagery.
53* ''Manga/LuckyStar'': The show also re-popularised anime merchandise and conventions. There has even been talk in the city council to make the local high school dress code match the one seen in the series. In turn, the girls became official honour residents of the city.
54* On August 1st, [[Anime/DigimonAdventure the day the original Digi Destined first went to the Digital World]], ''Franchise/{{Digimon}}'' fans meet up in Dai-san Daiba park in Odaiba, where the Digi Destined met up [[Anime/DigimonAdventure02 on the third anniversary of their Digital World adventure]]. Many western Digimon fans will make a point to visit Odaiba when visiting Japan as well.
55* The classical-music industry in the Asia-Pacific region has reasons to thank ''Manga/NodameCantabile''.
56* The eponymous character in ''Manga/{{Doraemon}}'' has a particular fondness for dorayaki, and when the show became a success, dorayaki also became extremely popular in Japanese bakeries and confection shops, not just in Japan, but in any region the anime is popular as well -- for example, Thailand, Malaysia, Indonesia, Singapore and The Philippines.
57* ''Manga/{{Gintama}}'' apparently did this to [[http://www.animenewsnetwork.com/news/2008-07-11/gintama-cited-for-g8-visitors-buying-wooden-swords wooden swords.]] it also helps that they were already ubiquitous in tourist shops and can't really be used as weapons (which means you can take them through customs more easily).
58* ''Manga/InitialD'' popularized the Toyota [=AE86=] Sprinter Trueno/Corolla GT-S by virtue of its protagonist beating seemingly much [[CoolCar cooler cars]] with one on a regular basis, simply with raw driving skill. It didn't help that the manga contributed to the car's high resale value, which made obtaining an 86 in good working order a challenge, let alone in mint condition.
59* ''Anime/WishUponThePleiades'' is a lesser example, with Subaru cars. This one is a weird sort of stealth-ProductPlacement: it was sponsored by Subaru, but their cars do not appear in the anime--instead, the protagonist is ''named'' Subaru (a relatively common name in Japan), and the characters' magic brooms make car-like noises and have contraptions attached to them that look suspiciously like front-grilles of Subaru vehicles.
60* Clarice's FairytaleWeddingDress in ''Anime/TheCastleOfCagliostro''. Former Princess Sayaka of Japan liked it so much that she had a real-world one made for her wedding dress.
61* Sports manga and anime, if they're successful, can create interest in that sport and cause many fans to take it up themselves -- not just in Japan, but around the world. Among those manga and anime:
62** ''Manga/CaptainTsubasa'' tremendously helped the development of soccer as a whole in Japan, spurring the creation of the national pro league JFA and thrust the sport from obscurity to the second-most played sport in the country. Many Japanese and non-Japanese players credit it for their inspiration to play soccer.
63** ''Manga/AttackNumberOne'' and ''Anime/AttackerYou'' did this for volleyball.
64** ''Manga/HikaruNoGo'' wound up ''tripling'' the number of TabletopGame/{{Go}} players in the world.
65** ''Manga/{{Chihayafuru}}'' did this for Karuta.
66** ''Anime/SummerWars'' did this for Hanafuda.
67** ''Anime/{{Saki}}'' did this for Reach Mahjong (Japanese Mahjong).
68** ''Manga/SlamDunk'' was a smash hit in not just Japan, but also the Philippines and Korea (and to a lesser extent, among Chinese teens in Malaysia). The manga was even credited by the Japanese Basketball Association for popularizing the sport in Asia, especially since a lot of the players in the Japanese league grew up reading it.
69** The writer of ''Rin!'' said that she received a lot of mail from fans saying they had taken up archery after reading the series.
70* ''Anime/TigerAndBunny'''s entirely unexpected popularity in Japan has led to the spike in sales for items only tangentially related to the show. The most notable was a brand of cologne that resembled a bottle the main character, Kotetsu, owned. [[http://i.imgur.com/VDs9V.jpg It was apparently of utmost importance to 2ch and /a/ to know what he smelled like.]] Sunrise noticed and decided that they'd start selling Kotetsu's oft-replicated hat.
71* As part of their 30th Anniversary for the ''Franchise/{{Gundam}}'' franchise, Sunrise commissioned a project to build an actual 1:1 scale 60ft tall statue of the show's flagship machine, [[Anime/MobileSuitGundam RX-78-2 Gundam]]. {{Downplayed|Trope}} in that unlike its fictional counterpart, the statue can't move due to the SquareCubeLaw making it infeasible and maybe impossible, but Sunrise has stated they would like to eventually "upgrade" the statue to be moving.
72* ''VisualNovel/SteinsGate'' features the soft drink of Dr. Pepper prominently, although it calls it Dk. Pepper instead, probably because of lack of sponsorship agreement. Nevertheless, this anime series boosted up the sales of Dr. Pepper considerably in Japan. The makers of Dr. Pepper itself have noticed this, and later launched an [[https://www.famitsu.com/news/201804/25156370.html official collaboration]] with the sequel series ''VisualNovel/SteinsGateZero''.
73* Lots of anime fans start learning the Japanese language, to the point where anime and manga fans make up some 60 percent of Japanese language classes. This actually causes an issue in that especially older anime and manga, even if they seem mature of American audiences, were made for a younger demographic in Japan. As a result, many fans who use anime as a basis for learning Japanese can come off sounding extremely odd to native Japanese speakers; they may end up sounding like either Japanese teenagers or grade-schoolers (with the danger of coming off TotallyRadical) or cartoon characters with purposely-idiosyncratic speech patterns. (Imagine someone learning English by copying child-aimed cartoons and you'll get the idea.) Similarly, the same can be said with Japanese dubs of Western products (including with those with a good amount of {{Woolseyism}}(s) for them)
74* ''Manga/KidsOnTheSlope'' has caused many people to get into jazz, particularly the '50s and '60s styles featured in the show.
75* Chanel lip balm [[http://en.rocketnews24.com/2016/11/24/a-figure-skating-anime-is-suddenly-boosting-chanel-sales-and-not-everyone-is-happy/ increased in sales]] after being used by Victor on Yuuri in Episode 5 of ''Anime/YuriOnIce''.
76* After ''Manga/LaidBackCamp'' was released, the red Yamaha Vino scooter thar Rin used surged in popularity, enough to completely sell out its stock.
77* Negi Haruba, the author of ''Manga/TheQuintessentialQuintuplets'', featured Miku Nakano wearing audio-technica's [[https://www.audio-technica.co.jp/atj/show_model.php?modelId=2898 ATH-AR3BT]] headphones and later, their [[https://www.audio-technica.co.jp/atj/show_model.php?modelId=2959 ATH-WS990BT]] headphones. This caused demand for both models to rise significantly. The company has recognized this, and [[https://twitter.com/negi_haruba/status/1099945721292156928?s=21 gifted Negi]] with a set of the latter model as thanks. Creator/AyaneSakura, who voiced Miku and her quintuplet sisters in [[https://www.youtube.com/watch?v=im3k9VYR8AQ a short commercial]] to promote the manga, also wore the former model as [[https://cdn-ak.f.st-hatena.com/images/fotolife/m/magazine_pocket/20171213/20171213212001.jpg part of a Miku cosplay]] in promotional photos.
78* Between the mid 1990s and early to late 2000s, Japan had an obsession with hamsters and were frequently used as either main characters or supporting characters in various children's media. Examples include:
79** The ''Anime/{{Hamtaro}}'' series caused many children to get pet hamsters. Especially with the amount of episodes and spin-off material that aired throughout the 2000s including a couple video games.
80** Predating ''Hamtaro'' is the ''Hamster Club'' manga series which ran for 12 volumes between 1994 till 1995. The series received 4 video games that were released on the Gameboy Color and Gamebody Advance and a Playstation game. It even gained a short-lived anime adaptation and a single [=OVA=] release. The series caused tons of Japanese children and women to get pet hamsters.
81** [[Creator/TatsuyamaSayuri Sayuri Tatsuyama's]] ''Pukupuku Natural Circular Notice'' manga series [[https://www.amazon.co.jp/images/I/5145B31H60L.jpg features a couple hamsters]] that serve as one of the main characters alongside Puku the puppy. The manga lasted from 1999-2004 with 10 volumes and 3 Gameboy Advance games. It also caused another surge of Japanese audiences wanting hamsters.
82** Creator/{{Sanrio}} got in on the hamster trend in 1998 by creating a Sanrio character named [[https://static.wikia.nocookie.net/hellokitty/images/5/56/Sanrio_Characters_Corocorokuririn_Image003.gif/revision/latest/top-crop/width/300/height/300?cb=20100814042701 "Kuririn" from the Coro Coro Kuririn series]]. The eponymous character is a golden hamster [[ExplosiveBreeder who had seven children with Sakura]], with his family and relatives all being different types of hamsters. The series caused children and women to become very fond of hamsters.
83* ''Manga/AkazukinChacha'' received a surge in interest after ''Literature/AnotherNote'' revealed Beyond Birthday is a fan of the manga.
84* In 2019, a tweet was posted about the Area 51 raid saying "If we ''Anime/{{Naruto}}'' run, we can move faster than their bullets. Lets see them aliens". Shortly after the tweet was posted, ''Anime/{{Naruto}}'' got extremely popular, and people flocked to the stores to buy the manga and headbands.
85* The ''Literature/SoundEuphonium'' anime was many viewers' first introduction to the [[https://en.wikipedia.org/wiki/Euphonium euphonium,]] an obscure concert band instrument that doesn't get much real spotlight otherwise.
86* ''Manga/KaguyaSamaLoveIsWar'' resulted in fans flocking to [=YouTube=] searching for videos related to [[https://www.youtube.com/watch?v=MwmB2eptXz0 Soran Bushi.]]
87* ''Manga/BocchiTheRock'': Sales of the Les Paul Custom and the Yamaha Pacifica went up when fans were inspired by this show to take up the guitar themselves.

90[[folder:Comic Books]]
91* The German comic ''ComicBook/{{Werner}}'' heavily [[ProductPlacement featured]] the beer from the then-small Flensburger brewery, which was obscure even in its home in northern Germany. It was known for being among the last few German beer brands sold in swing-top bottles. Then, when the comic popularized the brand, it got so popular in Germany that the brewery had trouble keeping up with demand. Then Werner made his own beer in the sixth book, which would be {{defictionaliz|ation}}ed (and stopped the free advertising for Flensburger).
92* "Fuck Communism" Zippo lighters only became popular ever since they were featured in ''ComicBook/{{Preacher}}''. These were not made up by Garth Ennis, but originally carried by US soldiers in Vietnam, who would often stamp the message along with the name of their company or platoon.
93* The ''Franchise/{{Transformers}}'' Wiki calls it the Bludgeon Effect: the franchise has many more toys created than there are characters in the TV show, and the ExpandedUniverse has a ''huge'' source of characters that you've never heard of and haven't even got a personality. The name refers to Bludgeon, a relatively minor character who became Decepticon leader late in the Marvel Comics run and stayed a prominent character in subsequent series -- much more so than his unpopular toy line would have indicated. This most commonly happens to characters [[ComicBook/TheTransformersIDW the IDW comics]] use to good effect; their toys' value online will skyrocket. The biggest beneficiary of this was not Bludgeon, but Ironfist, a character who had never been used in a story until a single appearance in an IDW comic and a Fun Publications comic. Good luck getting your hands on an intact version [[CrackIsCheaper for less than $100.]]
94* While pornographic [[UndergroundComics Tijuana Bibles]] generally feature in a very obscure subset of comic collecting, they saw a big surge of interest from ''ComicBook/{{Watchmen}}'' fans when that comic referenced the art form in a side-plot which explained in detail what they were. Tijuana Bibles continued to see surges in popularity years later with each new film and TV ''Franchise/{{Watchmen}}'' adaptation.

97[[folder:Films -- Animated]]
98* ''WesternAnimation/DespicableMe1'':
99** Real life carnival booths stocking real life Fluffy Unicorns have become a common sight.
100** More kids have been eating bananas as a snack since it's the Minions' TrademarkFavoriteFood.
101* Tourist visits to UsefulNotes/{{Norway}} spiked up to 34% after the release of ''WesternAnimation/{{Frozen|2013}}'', [[FantasyCounterpartCulture whose lore and setting was inspired by Norwegian culture and geography]] (even though the [[Literature/TheSnowQueen source material]] was written by [[Creator/HansChristianAndersen a Dane]]). The country now hosts ''Frozen''-themed family holidays to drum up publicity for those who are curious about the film's setting.
102* After the release of ''WesternAnimation/{{The Little Mermaid|1989}}'', there was a frenzy for mermaid-related products and media, something which still continues to this day.
103* ''WesternAnimation/SleepingBeauty'': Many a PrincessClassic in Western Animation will sport dresses inspired by or homaging Aurora's. A good amount of princess costumes in stores are based off it too.
104* The ''Franchise/ToyStory'' movies created a huge demand for many of the toys it featured.
105** It raised demand for simple plastic green army men so much that Creator/The3DOCompany started [[VideoGame/ArmyMen an entire video game series]] dedicated to the concept.
106** {{Franchise/Barbie}} dolls also got a boost from the second film, although Creator/{{Mattel}}'s paranoia almost prevented this from happening. Creator/{{Pixar}} had wanted to use Barbie in the first movie, but Mattel said no, objecting to her being used as a [[Franchise/{{Terminator}} Sarah Connor]]-esque badass. Then Mattel saw how the toys the movie ''did'' feature got a sales boost (particularly Mr. Potato Head), and they were only too happy to see Barbie used in the second and third movies (with something of a compromise in personality).
107** The Slinky company had previously taken the Slinky Dog off the market years before ''Toy Story''. They brought it back because of the movie, albeit modified to account for the character and due to stricter safety regulations.
108** ''WesternAnimation/ToyStory4'' prompted demand for a movie-accurate Gabby Gabby doll. However, Gabby Gabby has strangely not received a toy apart from smaller-scale action figures and plushies. This has led to some enthusiasts customising dolls of the same scale and design (such as [[Literature/AmericanGirlsCollection American Girl]] dolls, Disney Animator dolls, or Toys/ChattyCathy) to better resemble the character. There did eventually exist a full-sized Gabby Gabby doll with accurate clothes and hair--but it is [[NoExportForYou exclusive to Brazil]] having being made by a local toy manufacturer under licence. As to whether Thinkway Toys (or some other firm whom Disney has a contract with) would do a similar doll is anyone's guess.
109** As for Gabby's "very best friend" Benson, good luck trying to have one sculpted by a puppetmaker. A full-scale dummy can go for around several thousand dollars depending on how advanced the controls are. That isn't to say that a full-size Benson figure is out of the question as similar dummies can be had for under a hundred dollars--albeit as an entry-level dummy rather than a bespoke, professional-grade figure.
110* After ''WesternAnimation/TurningRed'' was released, popularity of red pandas increased rapidly, and many fans flocked to the zoos to see them, and some donated to wildlife centers to help save them.
111* While declining sales caused the last of the creameries which manufacture the centuries-old Wensleydale cheese to teeter on the edge of closure in the early '90s, Wensleydale received a chance mention in the popular ''WesternAnimation/WallaceAndGromit'' shorts. Noticing the increased interest, the creamery persuaded Creator/AardmanAnimations to endorse a ''Wallace & Gromit''-branded cheese, which worked to rebuild Wensleydale into a thriving product worldwide. The [[https://en.wikipedia.org/wiki/Stinking_Bishop_(cheese) Stinking Bishop cheese]] is also featured in a plot-critical moment in ''WesternAnimation/TheCurseOfTheWereRabbit''; sales of this niche culinary product rose by 500% after the film was released.
112[[/folder]]

114[[folder:Literature]]
115* ''Literature/OneQEightyFour'': During the 20 years of Janáček's ''Sinfonietta'' being available on CD, it sold 6,000 copies (so, 300 copies per year on average). [[https://web.archive.org/web/20130709165124/http://blog.japantimes.co.jp/japan-pulse/the-knock-on-effect-of-murakami%E2%80%99s-%E2%80%9C1q84%E2%80%9D-series/ Thanks to its inclusion]] in ''1Q84'' as a connection between lead characters Tengo and Aomame, the album sold the exact same number in only ''one week''.
116* ''Literature/SilenceOfTheLambs'', a book written by a criminalist and based on real events, managed to make police profiling and the profiling by female detectives more popular, even among actual police investigators. Before that, it was, to say the least, an underdeveloped (and [[http://www.newyorker.com/reporting/2007/11/12/071112fa_fact_gladwell questionably effective]]) investigative branch.
117* The popular children's novel ''Literature/LittleLordFauntleroy'' created a fad for dressing little boys in the style of clothing described and illustrated in the book, based on outfits author Frances Hodgson Burnett had designed for her own sons. And a generation later, there was a backlash against that kind of outfit for boys by fathers who remembered how much they'd hated them as youngsters.
118* Kate Greenaway's illustrations revolutionized Victorian fashions by creating a huge demand for the simpler, more relaxed outfits she'd designed for her adult and child figures.
119* In 1933, James Hilton wrote a book called ''Literature/LostHorizon'', where the survivors of a plane crash stumble upon a [[{{Utopia}} perfect utopia]] called Shangri-La. The book is obscure now, but Shangri-La and what it represents -- longing for a faraway place of beauty, spiritual replenishment, and supernatural longevity -- stuck around. When Tibet realized that heavy logging of their old-growth forests was causing disastrous floods, they turned to tourism, found that it paid really well, and renovated a village, renaming it Shangri-La.
120** There was an even odder two-step version during UsefulNotes/WorldWarII. When reporters asked President Roosevelt where the bombers for the Doolittle Raid came from, he blew off the question by joking that they took off from "Shangri-La." Shortly afterward the U.S. Navy launched a carrier named the U.S.S. ''Shangri-La'' (CV-38), which served until the [[UsefulNotes/TheVietnamWar Vietnam]] era.
121* ''Literature/HarryPotter'':
122** The books have reportedly increased the popularity of {{boarding school}}s among children in Britain.
123** The books feature a magical beverage called "butterbeer", which people in real life have been wanting to try. A beverage of that name ''did'' exist in the Tudor era (as [[https://www.youtube.com/watch?v=H_Jgq-VQE-o beer blended with butter, sugar, eggs, and spices]], kind of like a 16th-centuy eggnog), but these days everybody seems to have his own recipe for it -- including ''The Wizarding World of Harry Potter'' in Ride/UniversalStudios Orlando.
124*** There's also a soda called [[https://flyingcauldron.com/ Flying Cauldron Butterscotch Beer]], which is not affiliated with the Harry Potter franchise, but seems likely to have been inspired by it.
125** The books were also credited with a boost to the number of schoolchildren learning Latin, as the magic words for spells in the Harry Potter universe are normally a Latin (or [[CanisLatinicus Latin-ish]]) translation of the intended effect.
126* Goethe's ''Literature/TheSorrowsOfYoungWerther'', about a {{bishonen}} artist/poet who shoots himself when the love of his life marries the man she was already engaged to when Werther met her, was a huge bestseller in 1774, touching off a wave of copycat suicides. This cropped up again in Palestine in the 1930s when the book was published there. There was a huge demand for blue frock-coats and yellow vests as well, because Werther is described as wearing them. And the merchandise -- ''Werther'' perfume. And the fan fiction (in the 18th century, yet). ''And'' [[https://www.youtube.com/watch?v=njI4Mo84qeQ the opera]].
127* ''Literature/TheTwilightSaga'':
128** The town of Forks, Washington saw a [[TouristBump 600% increase in tourism]] after the books and the movies came out, nearly all of it due to it being the main setting of the series. There have even been a pair of {{documentar|y}}ies, ''Twilight in Forks'' and ''Destination Forks'', made about how the town has been affected by this. The ''Twilight'' tourism has also rubbed off on neighboring towns, most notably La Push (home of Jacob Black and the Quileute tribe) and Port Angeles (the main town on the Olympic Peninsula, and where several scenes from the book took place).
129** The restaurant Bella Italia in Port Angeles, where Bella and Edward have their first date, received so many requests for the mushroom ravioli that Bella orders in the book that they [[http://www.peninsuladailynews.com/article/20080801/NEWS/808010304 added it to the menu]] under the name of "Bella's Mushroom Ravioli." The {{defictionalization}} was taken a step further in 2011 when the dish was made available by the restaurant as [[http://www.bellaitaliapa.com/bellasmushroomravioli.php a frozen take-home entree.]]
130** ''Literature/WutheringHeights'' is enjoying a revival thanks to Bella's fondness for it (coupled with Edward's derision).
131* ''Literature/TheCountOfMonteCristo'' is the reason why the Chateau d'If, otherwise a random old prison in the south of France, is popular with tourists.
132* In Creator/WilliamGibson's ''Literature/PatternRecognition'', Cayce Pollard is a media consultant with an allergy to blatant commercial logos and certain fashions. She removes the label from all her clothes and wears drab black, grey, or white everything. She has one specific bit of clothing: a black Buzz Rickson's MA-1 jacket, a replica WWII flying jacket slavishly reproduced by Japanese clothing otaku, accurate down to the wobble in the stitching. Buzz Rickson's was real. The jacket was real. The quality was real. One problem: they didn't make them in black. [[http://www.buzzricksons.com/type-ma-wg-slender-p-48.html They do now.]]
133* ''Literature/TheHungerGames'' caused [[http://theweek.com/article/index/226318/how-the-hunger-games-made-archery-hot-again a spike]] in the popularity of archery, particularly among young women, thanks to its ActionGirl protagonist Katniss Everdeen being a bow hunter who makes heavy use of her archery skills throughout the books.
134* ''Literature/ChristianeF'', an autobiographical story about a teenaged drug addict from West Berlin, turned several, mainly German teenagers curious about a rather unfortunate product: Heroin.
135* ''Literature/TheDaVinciCode'' increased the popularity of the Mona Lisa, with hundreds of visitors wanting to view the painting because of the book and the film, as well as [[spoiler:the part of the Louvre where the Magdalene may or may not be buried]].
136* According to legend (though likely apocryphal), Sir Walter Scott's ''Literature/AnneOfGeierstein'' is supposedly the source of opals having bad luck; its protagonist dies shortly after her opal necklace is tarnished by holy water. The legend says that the book was popular enough that sales of opals dropped 50% in England after the book was published, and the market was only corrected after a large black opal influx from Australia. In fact, there is little contemporary evidence to support this claim.
137* This trope is the whole reason that we have ''Radio/TheShadow'' at all. Street and Smith was getting its clock cleaned in the detective-story magazine business in 1930, and so decided to latch on to a new gimmick -- dramatizing their stories on the radio. They chose as a narrator/host character a mysterious, vaguely sinister figure that soon became known as "The Shadow" (a nod to a Creator/CharlesDickens character who was a hypothetical newspaper reporter). While he wasn't intended to do more than usher in the stories and never actually figured in them (think "The Cryptkeeper" from ''Series/TalesFromTheCrypt''), the public fell in love with the character and demanded to know more about him. Whereupon Street and Smith hired Walter B. Gibson to begin writing novel-length stories of The Shadow in a new magazine devoted to him. And the rest is history.
138* The story "A Sound Like Someone Trying Not to Make a Sound," from Creator/JohnIrving's novel ''Literature/AWidowForOneYear'', was made into a children's book.
139* It's been said that as much as a third of all tourism to Prince Edward Island, Canada's smallest and least-populated province, is related to ''Literature/AnneOfGreenGables'', which is set there.
140* Creator/CliveCussler: Literature/{{Dirk Pitt|Adventures}}'s signature orange-faced Doxa SUB [=300T=] dive watch has become very popular. It was based on a watch Cussler actually owned[[note]]which was a parting gift given to him by the manager of a dive shop he worked at until he published his first novel[[/note]]. In fact, it was so popular that a fan started creating reproductions in 2001, decades after the original Doxa went out of business, and Cussler got the first in the limited run.
141* ''Literature/{{Roots}}'' (and especially its [[Series/Roots1977 miniseries adaptation]]) sparked a boom in interest in people tracing their ancestry and genealogy. This was partly the intention of the book's author Alex Haley, but while he mainly intended the book for a Black audience as a way of rediscovering family lineages that had been forgotten during slavery, it [[{{Applicability}} resonated far and wide]] and led to many White Americans doing the same with their ancestors in Europe.
142[[/folder]]
143
144[[folder:Music]]
145* Music/AvrilLavigne:
146** The music video for "[=Sk8er=] Boi" inadvertently resulted in a massive demand for Wilkesboro Elementary School shirts, much to the school's surprise and delight.
147** She also wore a Napanee Home Hardware t-shirt, a hardware store from her tiny Ontario hometown, for an appearance on ''Series/SaturdayNightLive''. The demand was such that the chain began producing them in large quantities and selling them nationwide.
148* Sales of deodorant Teen Spirit skyrocketed with the release of the Music/{{Nirvana}} song (and its [[Music/NevermindAlbum accompanying album]]). And plummeted after the song faded away. Far worse than burning out. [[HilariousInHindsight Not that Kurt Cobain knew Teen Spirit was a deodorant.]] He just liked the phrase after it was directed at him by his friend, Music/BikiniKill singer Kathleen Hanna -- he interpreted the phrase as a revolutionary slogan, but Hanna was merely lightly ribbing Kurt for smelling like his girlfriend's deodorant. Apparently he was quite disappointed to discover its origin. It's not nearly as clever as when he thought it was some kind of metaphor.
149* Thrift store and flannel clothing became popular after the mainstream success of various grunge bands. However, many of these bands were wearing them not to create a fad, but because they were the warmest clothes they could afford, and flannel clothing was (and still is) quite abundant in the northwest United States, where the {{Grunge}} scene originally developed. In fact the "look" becoming a fad annoyed many grunge artists, because they were playing in their everyday clothes in deliberate contrast to the excessive flashiness of 80's bands.
150** Music/NeilYoung raised (or lowered) the messy uncombed flannel look to a fine art. When he toured Japan in 1976, he was greeted in Osaka by hundreds of students in flannel shirts and jeans.
151** Sales (and prices) of Fender Jazzmaster, Jaguar and Mustang models, chosen by Cobain and his ilk as they were inexpensive, strange, unfashionable pawnshop guitars (and as Cobain had small hands and found the smaller necks easier to play) grew with Grunge's popularity. Similar, too, were the popularity of strange analog 1970's stompbox effect pedals grungers used to create their sounds.
152* During [[Music/TheBeatles Beatlemania]],
153** Anything a Beatle wore took off. One of the most famous is the moptop hair cut.
154** The Beatles connection certainly helped (and continues to help) sales of Rickenbacker, Hofner, and Gretsch guitars and basses, particularly those played by the band, as well as certain Epiphone, Fender and Gibson guitars, and Ludwig drums.
155** They were one of the first bands to use a Moog modular synthesizer (though Music/TheMonkees had them beat by two years), on the ''Abbey Road'' album in 1969, helping to pave the way for the popularity of synthesizers in pop music.
156** As far as studio technology is concerned, the fact that the Beatles used EMI [=REDD47=] mixers, Fairchild 660 and 670 limiters, Neumann U47 and U48 microphones, and Altec compressors to record their music, often pushing them in radical ways to produce the groundbreaking sounds they made, has led not only to new interest in the genuine articles, but plenty of hardware and software recreations of that gear. Oddly enough, even by 1960s standards it was relatively old-fashioned equipment, and Abbey Road Studios was slow to adapt new technology.
157** When George first played the sitar in "Norwegian Wood", fans wrote to the label and to radio stations by the millions, asking what kind of "guitar" that was. Overnight, the sitar was transformed from a classical and sacred instrument to an exotic pop sound.
158* Music/NancySinatra's hit song "These Boots are Made for Walin" was credited with further popularising go-go boots in TheSixties.
159* Music/QueensOfTheStoneAge singer/guitarist Josh Homme's use of the rare Ovation Ultra GP electric guitar has increased demand and prices for original examples.
160* Music/DireStraits' decision to place Mark Knopfler's National Style O resonator acoustic on the cover of their 1985 album ''Music/{{Brothers in Arms|Album}}'' resulted in a surge in demand for the guitars, leading to high prices which continue to this day.
161* It has been observed that a number of hit singles, even after their sales started to decline, have enjoyed spikes in their sales when Music/WeirdAlYankovic released parodies of them. Music/KurtCobain of Music/{{Nirvana}} once said, "I knew we had arrived when Weird Al Yankovic did a parody of us."
162** ...which was subsequently parodied on ''WesternAnimation/TheSimpsons'' by having Homer (in an episode in which he briefly became a grunge-rock star) watch Weird Al parodying his hit song on TV. To take the pop-cultural references one level further, Weird Al now uses a clip of that Simpsons episode as part of the visuals shown in his concerts.
163* Music/MenAtWork's "Down Under" is catchy enough that despite only mentioning the iconic Australian product once in the entire song, it drove up sales of Vegemite on its release.
164* Marching-band inspired jackets remain popular since Music/MyChemicalRomance's release of ''Music/TheBlackParade''.
165* Music/{{Outkast}}'s "Hey Ya!", with its repeated line of "Shake it like a Polaroid picture", helped boost the popularity of Polaroid cameras at a time when digital cameras were eroding their sales.
166* Due to Tommy Tutone's OneHitWonder known as "867-5309/Jenny", the United States has made said phone number invalid, except for businesses that buy it up for advertising purposes.
167* Music/EricClapton and Music/JimiHendrix drove up sales of the Fender Stratocaster and Gibson Les Paul in TheSixties to legendary status; neither model were known as high sellers at the time. The Les Paul had been discontinued for years when Clapton and his peers started using it. Not only did Gibson bring it back to great success, it also drove up the prices of the original 1950s models to insane levels. A 1959 Les Paul Standard is the most expensive guitar in the world, all thanks to Clapton (and the fact that only 643 of the guitars were made). Meanwhile Fender was on the cusp of discontinuing the Stratocaster when it was famously adopted by Jimi Hendrix. Sales of the guitar skyrocketed afterwards and it remains their flagship model to this day. Sales of high-wattage Marshall amplifiers also increased, along with effects boxes like wah-wah pedals, distortion boxes and phase shifters.
168* Certain musicians such as Ricky Wilson of Music/TheB52s, Johnny Ramone of Music/TheRamones, and Music/KurtCobain of Music/{{Nirvana}} greatly increased the popularity of Mosrite guitars. Mosrites were obscure guitars, but they had became popular in punk by virtue of being cheap (the Ventures models being popular). Wilson also based the entire sound of the early B-52s around the guitar's other-worldly, surfy tone, making the instrument highly sought after in the PostPunk scene. Nowadays, Mosrite guitars are rare and expensive because of the musicians who played them.
169* The use of cheaply made, red Montgomery Ward Airline electric guitars and Silvertone amplifiers by Jack White of Music/TheWhiteStripes (an attempt by Jack to make use of unconventional, limited, gritty, hard-to-manage-and-play gear as opposed to more popular and comfortable models) led to an interest in vintage lo-fi music equipment (and a reinterest in GarageRock in general).
170* Music/BrooksAndDunn's 1992 hit "Boot Scootin' Boogie", a song about line-dancing, sparked a renewed interest in line-dancing that lasted well into the late 1990s. The craze even inspired another song which lampshaded the sudden increase — Music/{{Shenandoah}}'s "If Bubba Can Dance (I Can Too)", which was inspired by a comment that one of the writers made after seeing a commercial for line-dancing lessons.
171* The saxophone solo in Music/GerryRafferty's "Baker Street" led to hugely increased sales of saxophones everywhere.
172* The Roland [=TB-303=] bass line synthesizer[=/=]sequencer was introduced in 1982, but didn't sell too well and production was ceased two years after its introduction. By the end of TheEighties, the price of a used machine had fallen from its original price of $400 to under $100. Some machines were bought for next to nothing by Chicago [=DJs=], who invented the [[HouseMusic Acid House]] genre on it by tweaking the sound generator while a sequence runs. When the genre became popular in the early [[TheNineties Nineties]], the [=TB-303=] was so in-demand and sought-after, that its value had risen to multiple times its original price.
173* Analog synthesizers were almost worthless during the beginning digital boom in the late 80s, but grew outrageously expensive after they helped make and popularize new electronic dance music styles only a few years later.
174* One of the many reasons why the Yamaha [=CS=]80 is so expensive is that it's the key element in Music/{{Vangelis}}' trademark sound, and many musicians want to sound like this. Just listen to the ''Film/BladeRunner'' soundtrack.
175* This applies to almost every electronic instrument or related device made before 1990 and played by Music/JeanMichelJarre, including guitar stompboxes and electronic organs (in particular, his famous sweeping string sound is made with a mid-class Dutch home organ and a phaser effect box). Add to this the fact that many Jarre fans and followers are electronic musicians themselves.
176* Subverted by ''Manta'' by Norbert & die Feiglinge, a song about a sports coupé made by Opel. What the song kicked off was not an increased demand (which was good in a way because the Manta was discontinued two years earlier) but a [[GermanHumour huge wave of jokes ridiculing the car and especially the drivers]], which ruined its reputation for many years.
177* The Clancy Brothers were single-handedly responsible for sales of [[http://en.wikipedia.org/wiki/Aran_sweater Aran sweaters]] in the US during the '60s and '70s.
178* The Kingston Trio's hit cover version of "M.T.A." in the early 1960s is supposed to have so badly damaged the reputation of Boston's Metropolitan Transportation Authority that it took its current name, Massachusetts Bay Transportation Authority, shortly afterwards to prevent the acronym from applying. But things have changed in the decades since. "Charlie", the protagonist of the song, has been the MBTA's official mascot, as used on its "[=CharlieCard=]" fare cards, since 2004.
179* Depending on who you ask, Music/{{Macklemore}}'s "Thrift Shop" song has either sent a surge of folks to thrift shops, or just "increased foot traffic" with little to no increase in sales ([[http://www.ibtimes.com/macklemores-thrift-shop-has-had-no-effect-actual-thrift-shop-revenues-1114394 as in the latter case with the thrift shops seen in the video and surrounding shops]]).
180* Far East Movement's "Like A G6" apparently resulted in people demanding to be able to fly in a G6, which Gulfstream Aerospace has not made, as they were still producing the G4 at the time of the song. They eventually got their wish in 2013 when Gulfstream released [[https://en.wikipedia.org/wiki/Gulfstream_G650 an actual G6.]]
181* Music/{{Ylvis}}' "The Fox (What Does the Fox Say?)" supposedly caused a surge in the sale of fox Halloween costumes.
182* Haircuts sported by the likes of Music/JustinBieber and Music/OneDirection, took off amongst teenagers at the height of their popularity.
183* The enormously successful 1892 song "Daisy Bell" preceded the popularity of tandem bicycles, and was probably at least partly responsible for creating the fad.
184* Music/TheWho's ''Music/{{Quadrophenia}}'' album, as well as its accompanying film, has been credited for kick-starting the mod revival of the late '70s and early '80s. It also made Vespa scooters cool again.
185* The weekend that Music/{{Beyonce}} released "Formation", in which she mentions Red Lobster, the chain reported a 33% increase in sales.
186* A Japanese song made to promote fish called "Osakana Tengoku" [[note]] Fish Paradise[[/note]] not only increased sales of fish in Japan, but [[http://web-japan.org/kidsweb/archives/cool/02-01-03/osakana.html made children in the country more willing to eat fish]].
187* The yellow heart-print Fernandes guitar owned by Music/HidetoMatsumoto has become so iconic in the years after his death, that much of the merchandise sold today include that particular pattern.
188** Similarly, the Killer Dagger bass is almost exclusively bought and used by fans of Music/TaijiSawada, especially outside of Japan where the brand was never available except via import.
189* The Saiai brand of saké enjoyed a surge in demand when {{Music/Babymetal}} fans discovered the brand shares the same kanji characters with Moametal's given name. The Yui-no-Mizu mineral water experienced the same to a lesser degree.
190* UsefulNotes/{{Houston}} hip-hop producer DJ Screw played a major role in the popularization of purple drank, aka lean, sizzurp, or syrup, a drug created by mixing promethazine codeine cough syrup with soda pop. The Music/ThreeSixMafia song "Sippin' on Some Syrup" solidified its reputation as a legal high of choice for chilling out. Actavis, maker of one of the more popular cough syrups for this purpose, eventually [[https://www.vice.com/en_us/article/9bz3gv/sizzurp-is-the-new-quaalude pulled it]] from store shelves in 2014 once they realized where most of their sales and popularity were coming from, not wanting to risk lawsuits.
191* The National Suicide Prevention Lifeline reported a large jump in caller traffic when rapper Logic's song 1-800-273-8255 (which is the number of the lifeline) began hitting the charts, with call rates [[https://www.cnn.com/2017/08/25/health/logic-suicide-hotline-vma-18002738255/index.html increasing 50%]] the night he performed it live at the Video Music Awards.
192* Music/TheTragicallyHip's "Bobcaygeon" garnered interest in increased tourism of the eastern Ontario town of the same name. The largest community events in Bobcaygeon's history included a viewing of the Hip's last tour, and a candlelight vigil for their late frontman Gord Downie. Despite this, the song is not about the town but the name was included to complete a rhyme.
193* It's [[https://www.sprucecanyonfamilydentistry.com/blog/invisalign-making-waves-because-of-one-song/ been reported]] that Invisalign sales have increased since the release of Music/BillieEilish's "bad guy," due to the video opening with Billie taking hers out. A few interviews also mention that Invisalign could be considered [[https://genius.com/a/billie-eilish-s-brother-compares-her-invisalign-removal-to-lil-wayne-s-lighter-flick part of her image]] as a performer.
194* In one of the more bizarre examples of the phenomenon, Music/{{BTS}} member Jungkook managed to [[https://www.koreaboo.com/news/jungkook-downy-saga-stir-business-circles/ cause a nationwide shortage of the fabric softener Downy in South Korea by simply mentioning he was using it to do his laundry.]] Once Downy caught up to demand, they later partnered with BTS to release fabric softener branded with their mascot characters.
195* Music/TaylorSwift's 2020 quarantine album ''[[Music/{{Folklore2020}} folklore]]'' caused a surge for Internet search for [[https://www.vogue.com.au/culture/lifestyle/what-is-cottagecore-the-phenomenon-made-popular-by-taylor-swift/news-story/6f4f501ffaee50c73f394d64f1ada174 cottagecore aesthetic]] and sale of [[https://www.thetimes.co.uk/article/taylor-photo-sparks-swift-sales-jump-for-aran-sweaters-s75xckv7k Aran sweaters]].
196* Music/OliverTree's iconic pink and purple Montbell windbreaker caused demand of the jackets amongst his many fans, but the actual jacket he wears is quite rare, so it lead to increased demands of any windbreaker jackets that are the same colors.
197* The popularity of [[Creator/{{Pinkfong}} "Baby Shark"]] lead to an increase in demand for shark-themed media.
198* Music/{{Pendulum|Band}}: Rob Swire's use of the Starr Labs Ztar Z6 model MIDI guitar controller on songs where he does vocals led to MIDI guitar controllers regaining popularity.
199* The Revelaires' ''The Joy of Knowing Jesus'' became a coveted collector's item among AlternativeRock fans thanks to the release of Music/{{REM}}'s "Voice of Harold", a B-side in which Michael Stipe sings the album's liner notes to the tune and backing track of [[Music/{{Reckoning}} "7 Chinese Bros."]] On [[https://www.discogs.com/release/5678147-The-Revelaires-The-Joy-Of-Knowing-Jesus Discogs]], copies of the album sell for at ''least'' a couple hundred dollars or so.
200* Faygo would be another obscure, regional soft drink brand from the Midwest if not for the Music/InsaneClownPosse making it their [[TrademarkFavoriteFood Trademark Favorite Drink]], referencing it several times in their lyrics (most notably the song "Juggalo Juice", which may as well be an unofficial three-minute commercial for it) and spraying the crowd at their concerts with it. The band has asked about collaborating with Faygo on a limited-edition product run, but Faygo, knowing the band's raunchy reputation, has always politely refused.
201[[/folder]]
202
203[[folder:Music Videos]]
204* Virtually every music video is a commercial for both the artist as well as the fashion worn in the video.
205** A famous example is the red jacket worn by Music/MichaelJackson in the music video of ''Beat It'' from ''Music/{{Thriller}}'', which led to increased sales, especially among black teenagers.
206* English electronic music duo Groove Armada released their single [[https://www.youtube.com/watch?v=JxohJX9ElpE My Friend]] on 5 November 2001, and around Christmas 2019, the "Let It Rock" crop top worn by one of the female models in the video (believed to be the protagonist) is still highly in demand, although it's not known who produced it, or the identity of the actresses who wore it. As of 2022, it's ''still popular'' [[ExaggeratedTrope to the point people on social media]] really want it.
207* Music/KatyPerry's video for "Part of Me" made the Volvo 200 series a somewhat popular car again, with the 260 model being particularly collectible. The version in the video was a U.S.-spec 240 GL 2.3 sedan, 1991 model year.
208[[/folder]]
209
210[[folder:Newspaper Comics]]
211* A doll of the Pointy-Haired Boss was made, after fans demanded one, seeing one depicted in the ''ComicStrip/{{Dilbert}}'' comic strip.
212[[/folder]]
213
214[[folder:Professional Wrestling]]
215* Mexican ProfessionalWrestling fans have made a tradition of wearing a replica of their favorite wrestler's mask when they go to the shows. This show of support also made inroads north of the border, with the success of masked wrestlers like Wrestling/{{Rey Mysterio|Jr}} and [[Wrestling/GregoryHelms The Hurricane]].
216* Wrestlers will often wear their own merchandise as product placement or simply as part of their entrance/ring gear. On occasion they don't have merchandise to begin with and their gear gains popularity, leading to this trope.
217** Wrestling/KevinOwens's most iconic T-shirt in the WWE is one he made last-minute out of a regular black shirt and duct-tape. WWE would later produce their own version with a decal instead of duct tape.
218** Wrestling/TheNewDay attached their stable's logo to matching track suits as a way to get around the company's dress code. This would later be turned into official merchandise.
219* In Japan, pro wrestlers Wrestling/AntonioInoki and [[Wrestling/SatoruSayama Tiger Mask]] have done as much to popularize martial arts as Creator/BruceLee did in United States. Many martial artists unrelated to pro wrestling, like judokas, karatekas, amateur wrestlers and MMA fighters, have confessed being sucked into the martial arts world during their childhood by watching Inoki or Tiger kicking and grappling evil foes in the ring. The same can be applied to United States as well, given that many a sport wrestler can tell he begged to join the school club out of love for the WWF.
220[[/folder]]
221
222[[folder:Radio]]
223* ''Radio/TheAdventuresOfSuperman'' inverted this trope significantly. In 1946, Florida-native activist Stetson Kennedy had infiltrated the Ku Klux Klan and learned its secret greetings and rituals, but the Klan at this time had grown powerful enough that the police were reluctant to stand up to them. He decided instead to pitch a story to the producers of ''The Adventures of Superman'' in which Superman takes on an {{Expy}} organization called "The Klan of the Fiery Cross". The 16-episode arc revealed the Klan secrets that Kennedy had discovered, stripping the Klan of much of its air of menace and mystery. As a result, new recruitment for the Klan dried up to almost zero within a few weeks of the initial episode broadcasts, and Kennedy and his episodes were regarded by some as "the single greatest contributor to the weakening of the Klan." [[http://dangerousminds.net/comments/how_superman_singlehandedly_thwarted_the_ku_klux_klan Read more here.]]
224[[/folder]]
225
226[[folder:Theatre]]
227* In the Netherlands, after a show of the famous comedian Youp van't Hek in which he had a short skit about Buckler beer (non-alcoholic) not being manly, sales dropped so bad that shortly after, up till this day, you cannot buy Buckler beer in Holland. In other countries you still can.
228* ''Theatre/{{Rent}}'' inspired an expensive clothing line to emulate the $5 rummage sale look.
229* Music/PyotrIlyichTchaikovsky's ballet ''Theatre/TheNutcracker'', [[AdaptationDisplacement based on a book]], is likely responsible for the association of Christmas with humanoid nutcrackers wearing 19th-century soldiers' uniforms.
230* Before it became a symbol of gangsters during TheRoaringTwenties (and an almost symbol of douchebaggery now), the fedora was once a fashion accessory ''for women'' due to the late Victorian actress Sarah Bernhardt wearing it in her play called ''Fédora''. Soon after, women wanted that soft felt hat as their symbol for women's rights, and about a few decades later, the hat had been passed down to men from [[DamnItFeelsGoodToBeAGangster gangsters]] to [[HardboiledDetective private detectives]] to [[Franchise/IndianaJones Nazi-asskicking archaeologists]] as [[FedoraOfAsskicking a symbol of badassery]], and the rest is history.
231* The 1907 production of ''Theatre/TheMerryWidow'', starring English actress [[https://en.wikipedia.org/wiki/Lily_Elsie Lily Elsie,]] paved way to the rise of the wide-brimmed overly-feathered hat that would remain popular during the rest of TheEdwardianEra until the dawn of WWI.
232* In 1923, when the Broadway musical ''Runnin' Wild'' started playing an unusual yet lively piano stride number, it started a national sensation. And adding it with energetic dance kicks, TheRoaringTwenties DanceSensation ''Charleston'' was born. The play was then almost forgotten, making it an early example of a BreakawayPopHit.
233* ''Theatre/{{Hamilton}}'' is credited with causing a '''huge''' resurgence of interest in the lives of both UsefulNotes/AlexanderHamilton and Aaron Burr, which helped turn Ron Chernow's 2004 biography of Alexander Hamilton (Creator/LinManuelMiranda's [[InspiredBy primary inspiration]]) into a massive bestseller when the play was at the peak of its popularity; sales of Creator/GoreVidal's 1973 {{historical fiction}} novel ''Burr'' similarly skyrocketed, with the publisher even advertising directly to ''Hamilton'' fans.[[note]] Interestingly, ''Burr'' is effectively a [[SpiritualAntithesis direct antithesis]] to the musical, portraying Aaron Burr in a comparatively positive light while portraying Alexander Hamilton as a much more villainous and unsympathetic figure[[/note]]
234[[/folder]]
235
236[[folder:Video Games]]
237* ''VideoGame/BitLife'' has potential InUniverse examples if you're a CEO; experts may predict increased demand for your product if it appears in a popular TV show or movie.
238* ''Franchise/{{Pokemon}}'':
239** With so many Franchise/{{Pokemon}}, treating every Pokémon equally in regards to official merchandise is nearly impossible. What ends up happening is that sales of a particular Pokémon's merchandise correlates strongly with which ones are showing up in other media, mostly the [[Anime/PokemonTheSeries anime]]. It's not as predictable as you'd think, though; while the super-cute (Pichu, Jigglypuff) and the super-cool (Charizard, Zekrom) have had their runs, even weird Pokémon like [[http://sunyshore.com/electric_fishies_maggyozukan.shtml Stunfisk]] get theirs.
240** ''VideoGame/PokemonSunAndMoon'': Google searches and interest for malasadas shot up since the game's release.
241* ''Franchise/TheLegendOfZelda'': The massive success of ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' resulted in a massive spike in ocarina sales, specifically potato ocarinas like the one used in the game. Music stores sold out of ocarinas and couldn't keep up with demand. To this day, Renaissance Fairs still sell baby-blue transverse ocarinas, usually with a Triforce-like sign to indicate them. Songbird Ocarinas was the first to do that; they ran ads in ''Magazine/NintendoPower'' for at least ''12 years'' up until its cancellation (from 1999 to 2012).
242* ''VideoGame/TeamFortress2'': Ask around any knife/blade shop and chances are they have had a number of people asking about butterfly knives, thanks to that globetrotting rogue, the Spy. The game is also responsible for the popularity of real-life hat obsession among its fans, though part of it is also due to said fans wanting to {{Cosplay}}.
243* After a [[http://en.wikipedia.org/wiki/Suwa_Taisha Suwa Taisha]]-inspired shrine made its way into [[Franchise/TouhouProject Gensokyo]], the real-life shrine saw a significant increase in pilgrimages.
244* The town that ''VisualNovel/HigurashiWhenTheyCry'''s Hinamizawa is based on had to build a new shrine wall because of the fans.
245* ''VideoGame/GuitarHero'' and ''VideoGame/RockBand'' have drastically increased the younger fanbases of Music/JudasPriest, Music/IronMaiden, Music/{{Rush|Band}}, Music/{{Kiss}}, and many other old-school bands, and given many other bands like Music/{{Dragonforce}} big career leg-ups.
246* ''VideoGame/KanColle'' has also increased the sales of ship model kits in addition to its own action figures. Previously, there were not many buyers for less well known ship models; most collectors will only get famous ones like Yamato. Demands of less known ship models rose significantly as the game increase in popularity with many collectors looking for model kits of cruisers and destroyers as well instead of just the famous ones. Even more so now with other games like ''VideoGame/WorldOfWarships'' in tow.
247* In ''VideoGame/{{Persona 3}}'', one of the social links involves playing an online MMO themed around the ''Franchise/ShinMegamiTensei'' series. The character involved in the link mentions that the MMO does not have a lot of players and is dying. Cue the {{defictionalization}} into ''VideoGame/ShinMegamiTenseiIMAGINE'', a game based on the ''Shin Megami Tensei'' series where, following a very obscure release and some very bad choices on the developer's part, one of the most frequent complaints until it finally shut down in 2016 was that the game does not have a lot of players and is dying.
248* ''VideoGame/GranTurismo'' has done this with its featured cars. the Mitsubishi Lancer Evolution and Subaru Impreza WRX [=STi=] series of high performance rally cars were brought over by their respective makers to the United States thanks to the game. It also caused demand for the Nissan Skyline GT-R in the U.S. (even though it was in DevelopmentHell at the time), although the final product that made it there wasn't nearly the same as what was in the game.
249* The appearance of a car resembling [[https://en.wikipedia.org/wiki/Daihatsu_Wake the Daihatsu Wake]] being worked on by Miyo Harada in [[https://cdn.donmai.us/original/ec/83/__producer_and_harada_miyo_idolmaster_and_3_more__ec83fe177ca54dc44be20f04ae03c6dc.jpg a tie-in manga panel]] for ''VideoGame/TheIdolmasterCinderellaGirls: Starlight Stage'' led to an increased interest in the car by her "producers." An official Daihatsu Twitter account even retweeted [[https://twitter.com/daihatsu_9ra9ru/status/1348796232001413122 a post where a player bought a Daihatsu Wake because of the issue.]]
250* ''VideoGame/NoMoreHeroes'': While it's not really a big seller, you can still buy Travis Touchdown's sweet leather coat.
251* A bakery nearby the Creator/{{Valve|Software}} company HQ enjoyed a spike in black forest cake sales after ''VideoGame/{{Portal}}'''s release and [[TheCakeIsALie subsequent]] RunningGag.
252* [[http://www.escapistmagazine.com/news/view/97789-Gun-Enthusiasts-Complain-About-the-Call-of-Duty-Effect One firearms blogger]] refers to this as the "''VideoGame/CallOfDuty'' effect"; video games will lead to the increase in popularity among certain guns. ''VideoGame/ModernWarfare 2'', for instance, led to an increase in interest in the experimental and formerly obscure Bushmaster ACR rifle. The same goes for airsoft copies of certain guns; one company, KWA, had its stock of Beretta 93R machine pistols sell out in record time after ''Modern Warfare 2'' featured it as one of the best sidearms in its multiplayer component. It's very disconcerting to gun enthusiasts, because many of these guys don't know UsefulNotes/GunSafety, are out to "[[BoomHeadshot headshot]] some {{noob}}s," and want way more than could ever be practical. Website/YouTube gun vlogger Nutnfancy [[https://youtu.be/dXihLnAx_tw?t=7m5s has noted]] that these people will buy the "military grade" versions of these guns, with all the bells and whistles like in the games, regardless of [[AwesomeButImpractical whether they have a measurable effect on performance.]]
253** On the other end of the spectrum are "Wasteland Builds" where gun enthusiast gamers will build or modify rifles (usually AK platform rifles, though occasionally G3 clones too) to match the aesthetic or even replicate specific in-game weapons from the ''VideoGame/{{STALKER}}'', ''VideoGame/{{Fallout}}'', or ''VideoGame/{{Metro 2033}}'' series. Said builds tend to involve lots of duct tape, scrap metal, and forum posts with cheesy fake Russian accents.
254* The expansion pack for ''VideoGame/SWAT4'' featured a stun gun that held two cartridges instead of one. A few years later came the TASER X2 Defender, which holds two charges. Even better, around the same time was the TASER X3, which holds ''three''.
255%% [Maybe an example, but you didn't link it to an increase in demand from the work's popularity.] * The popularity of the ''VideoGame/{{STALKER}}'' games has led to an increase in Chernobyl tourism and [[http://chornobyl.in.ua/en/real-stalker.html the real life "stalker" phenomenon]].
256* Any fantasy-based game of reasonable popularity will quickly find its weapons and armour converted into LARP props. The glass and Daedric weapons from ''VideoGame/TheElderScrollsVSkyrim'', the Master Sword and Hylian Shield from ''Franchise/TheLegendOfZelda'' series, and several of the famous ''VideoGame/WorldOfWarcraft'' pieces are frequent appearances at big meets, and there are even some examples of the equipment used in ''VideoGame/{{Minecraft}}'', complete with the original blockiness.
257* ''VideoGame/WorldOfTanks'' has gotten in on the act. Scale model sales have gone up as a result of the game to the extent that some companies and stores even offer special World of Tanks bonus codes for buying specific model kits. On top of that, the game also has a virtual replica of the title tank from ''Film/{{Fury|2014}}''. Oddly enough, with all the royalties being paid out, Wargaming has decided to go on a restoration spree by channeling some of the money they make from the game into restoring old tanks, ships, and planes to a showable (if not flyable/drivable/sailable) condition. Even their [[DuelingGames rival, Gaijin Entertainment]], the makers of ''VideoGame/WarThunder'' has gotten in on this, and are also restoring old tanks and planes to further preserve them.
258* ''VideoGame/SuperSmashBros'' is well known for its role in this effect: obscure franchises which receive representation in this series have seen their popularity explode following their appearance. ''VideoGame/KidIcarus'' sees this the most: ''[[VideoGame/SuperSmashBrosBrawl Brawl]]'' was largely, if not entirely, responsible for its eventual [[VideoGame/KidIcarusUprising reboot]]. ''Franchise/FireEmblem'' also appeared in the west following ''Smash'' appearances. And ''VideoGame/EarthBound1994'' got VindicatedByHistory, and its [[VideoGame/EarthboundBeginnings predecessor]] finally released outside of Japan, thanks to Ness's appearance in ''Smash'' convincing people to give the game a second chance.
259* Similar to ''Super Smash Bros'', ''Franchise/KingdomHearts'' occasionally gives exposure to an obscure Creator/{{Disney}} property which proceeds to become much less obscure.
260** Before ''VideoGame/KingdomHeartsI'', ''WesternAnimation/TheNightmareBeforeChristmas'' had a following but wasn't exactly what you'd call a Disney classic. Most people didn't even know it was a Disney film, as it was released under the Touchstone banner. But [[GermansLoveDavidHasselhoff it's always been regarded as a Disney classic overseas]], so it was included in the game, leading to its American fandom becoming much more mainstream. Disney made [[VideoGame/TheNightmareBeforeChristmasOogiesRevenge a video game sequel to the film]], started putting their name on future home video releases, and re-released the film in 3D.
261** ''VideoGame/KingdomHeartsII'''s inclusion of a ''Film/{{Tron}}'' world can probably take the credit for the existence of ''Film/TronLegacy'' and the little franchise that sprung up around it.
262** Thanks to the OptionalBoss of ''VideoGame/KingdomHearts3DDreamDropDistance'', a whole new generation rediscovered ''WesternAnimation/RunawayBrain''. Downplayed with ''WesternAnimation/MickeyDonaldGoofyTheThreeMusketeers'', easily the most obscure Disney property ever to get a ''Kingdom Hearts'' world, which people became more aware of but didn't enjoy any particular boost in popularity.
263* ''VideoGame/TonyHawksProSkater'' has been [[http://www.easternecho.com/article/2017/04/the-magic-of-tony-hawks-pro-skater credited,]] including by [[https://web.archive.org/web/20120726051959/http://www.gamerlive.tv/article/skateboarding-legend-tony-hawk-looks-back-his-video-game-legacy Tony Hawk himself,]] with providing a massive surge to the popularity of skateboarding and extreme sports in general in the early 2000s. Many young people from that time first picked up a skateboard after playing the games, and while it wound up a passing fad for many, a great number of professional skateboarders today credit the series with getting them interested in the sport.
264* Moira wields a Surefire 6P flashlight in ''VideoGame/ResidentEvilRevelations2''. Capcom anticipated this trope and launched a Biohazard-branded limited edition model as promotional material for the game.
265* After the ''VideoGame/{{Arknights}}'' character Skadi was given [[https://gamepress.gg/arknights/skin/riding-waves-wr04 a summer-themed skin]] that replaced her weapon with [[NerfArm a red orca plush]], enough players flocked to manufacturers of similar plush toys to ask if they made them in red that [[https://www.reddit.com/r/arknights/comments/ibc4pm/so_i_saw_this_on_fb/ at least one company made thousands of extra sales from it]].
266[[/folder]]

268[[folder:Web Animation]]
269* Zippo did not make cigarette lighters with the BMW logo on them until [[WebAnimation/HomestarRunner Strong Bad]] was repeatedly seen using a BMW lighter.
270[[/folder]]
271
272[[folder:Webcomics]]
273* Damn near anything in ''WebComic/{{Homestuck}}''. At its peak, any piece of real life memorabilia or item it referenced, like Gamzee's love of Faygo soda or John's hatred of gushers, was sure to drive up purchases from real life fans. Double for any obscure movies it referenced, and triple for the actual clothing of the protagonists. The official Homestuck shop made sure to keep real life versions of character outfits on hand, usually simple white Tees with their logos. Special mention goes to Dave Strider, whose sunglasses and red-sleeved shirt variant was a cheap and popular option for cosplayers.
274[[/folder]]
275
276[[folder:Web Original]]
277* ''WebVideo/CriticalRole'' brought a NewbieBoom to ''TabletopGame/DungeonsAndDragons'', and especially its Fifth Edition, thanks to the success of the show. The Exandria setting created by Creator/MatthewMercer for his table eventually got its own official campaign setting published by Wizards of the Coast. All of this was completely unintentional; Mercer has stated that [[AndYouThoughtItWouldFail he thought the series would last maybe six episodes before he and his friends just went back to his house and played there]].[[invoked]]
278* Creator/LordKaT's renewed interest in the game ''VideoGame/{{Starsiege}}: VideoGame/{{Tribes}}'' during February of 2011 caused the number of online players to surge 300% (and earned [=LordKat=] the nickname "Savior of Tribes").
279* ''WebVideo/TheSpoonyExperiment'': Spoony's review of the 1994 PC game ''VideoGame/BloodwingsPumpkinheadsRevenge'' had gamers hitting the used game stores and bargain bins in droves, searching for the obscure title. Which, in turn, nicely remedied his problem of not being able to find any info on it.
280* The goal of any given LetsPlay is usually to show off one of the player's old favorites, in the hopes that people watching it try the game out for themselves.
281** Big name [=LPers=] are able to bring spikes in popularity to otherwise unknown franchises. LetsPlay/{{Chuggaaconroy}}, for example, has helped the popularity of what were at the time relatively unknown games like ''VideoGame/{{Okami}}'' and ''VideoGame/XenobladeChronicles1''.
282** Indie developers have lately begun exploiting this by giving well-known Internet personalities permission to LP their games shortly after their initial release. Website/SomethingAwful, the place Let's Play began at, even had to remove its rule about not LP'ing a game until three months after it came out because of the number of indie/early access titles people wanted to and were being given early permission to show off.
283* A popular e-mail urban legend involved a customer being charged an exorbitant amount for a Neiman-Marcus cookie recipe, and in retaliation was distributing it for free over the Internet. Neiman-Marcus did not even sell a cookie at the time, but began to do so after the rumor started. And they give away the recipe for free. The urban legend was previously told about many other popular recipes, including a red velvet cake supposedly offered (it wasn't) by the Waldorf-Astoria Hotel in New York. William Poundstone wrote about the phenomenon in one of his ''Big Secrets'' books.
284* Maddox, of Website/TheBestPageInTheUniverse, hates this trope, and directs [[http://www.thebestpageintheuniverse.net/c.cgi?u=sideways his rant on the subject]] at ''Film/{{Sideways}}'' specifically. He figures that, if you're so impressionable that a movie is going to radically alter your opinion on something, you [[TooDumbToLive don't have any business being allowed out of the house to begin with]].
285* Creator/WilWheaton's ''WebVideo/{{Tabletop}}'' series has had this effect on several of the games it's featured, and it's now not uncommon to enter your Friendly Local Gaming Store and see 'as seen on Tabletop' signs next to games. The most notable example of this is ''TabletopGame/BetrayalAtHouseOnTheHill'', which was out of print at the time it was featured on the series. Increased demand saw it get a shiny new edition it probably wouldn't have had otherwise.
286* Michael from ''WebVideo/{{Vsauce}}'' managed to do this to a ''word''; his video titled [[https://www.youtube.com/watch?v=fCn8zs912OE "The Zipf Mystery"]] at one point talks about the word "quizzaciously" (meaning "in a mocking manner"), which is a word that's only appeared ''once'' in Google search results, at the time before the video's release. After the video's release, [[https://www.reddit.com/r/quizzaciously/ a subreddit]] was made and the word gained so many mentions all over the 'net.
287* In 2004, Sanei released a series of ''Mario Party 5'' plush dolls. These plushes are notorious for fetching high after-market prices thanks to their usage in ''WebVideo/SuperMarioLogan'' and other similar series. The 7-inch Luigi in particular can go for over $300 (though its actual value is closer to $100).
288* ''WebVideo/{{Davie504}}'': Davie has managed to spark interest in the bass as an instrument. Before, despite being considered one of the most important instruments in music, it remained relatively obscure outside of music fans. With his shift in channel audience to a more general audience, many more of the general public have been exposed to the bass and have picked it up themselves.
289[[/folder]]

291[[folder:Western Animation]]
292* ''WesternAnimation/KimPossible'':
293** A mother in Finland once wrote an article stating that ''Kim Possible'' encouraged her daughter to take up cheerleading and martial arts lessons.
294** Fans credit this with Taco Bell's creation of the Crunchwrap Supreme, as it is very similar in concept to the naco. Taco Bell would also introduce Diablo sauce in black packets much like the ones on the show.
295* Played with in ''WesternAnimation/KaBlam'', which had a scene in an episode where Henry and June show the audience their poseable action figures. After it aired, kids across the US searched in Toys R Us/Wal Mart/Target for H&J toys. They don't exist.
296* ''WesternAnimation/SouthPark'':
297** After the Music/LadyGaga song "Poker Face" made an appearance in an episode where the boys are playing ''VideoGame/RockBand'', the song quickly made it into the real game. Even better? ''So did Cartman's version.''
298** The Casa Bonita episode affected the real version so much that [[https://youtu.be/S6k26GDq9_0?t=12m17s they have to track down whenever the episode airs]] to accommodate for a potential increase in business. In 2021, Trey Parker and Matt Stone would end up buying the real-life Casa Bonita after it went bankrupt.
299* Inverted with ''WesternAnimation/ACharlieBrownChristmas''; the special's denouncement of aluminum Christmas trees is credited with helping kill the fad.
300* Mondelez International, the makers of Toblerone, reportedly saw their share prices increase after the release of ''WesternAnimation/NeoYokio'' and the famous "[[MemeticMutation You don't deserve this big Toblerone]]" scene.
301* During its peak in TheNineties, ''WesternAnimation/TheSimpsons'' became the arbiter of what was "In" and what was "Out" in American popular culture.
302** It has been credited/blamed (depending on your perspective) for the declining acceptance of nuclear energy among Americans due to its portrayal of the Springfield Nuclear Power Plant, staffed by morons like Homer and his friends and run by a CorruptCorporateExecutive who, among other [[CuttingCorners cost-saving measures]], dumps nuclear waste straight into a nearby river to save money. The U.S. Council for Energy Awareness, a nuclear energy industry association, even sent a letter to the show's producers expressing their horror at how the nuclear plant was portrayed. Dan Sarto, [[https://www.awn.com/blog/nuclear-energy-industry-simpsons-was-no-laughing-matter writing]] for the Animation World Network, believes that ''The Simpsons'' damaged the reputation of nuclear energy far more than the UsefulNotes/{{Chernobyl}} meltdown; whereas that could be written off as simply [[MadeInCountryX the failures of Soviet engineering]], ''The Simpsons'' portrayed American nuclear power plants as being no better.
303** School bands saw an increase in female sax players once Lisa became a popular character.
304** One episode inverts this in-universe, and then exaggerates it: Homer's signature blue pants are worn out and he looks for a new pair, but after a disastrous Super Bowl ad, blue pants are discontinued. After offering to use his head as a billboard, sales of blue pants surge and everybody uses them... even the Invisible Man.
305* ''ComicStrip/{{Popeye}}'' and its use of spinach as a PowerUpFood led to people eating more spinach. Crystal City, TX has a statue of Popeye as thanks, since spinach is the city's staple cash crop.
306* ''WesternAnimation/StevenUniverse'' got people to start collecting gemstones, prompting warnings to be sent out that certain minerals -- such as lapis lazuli and (appropriately enough) malachite -- are highly toxic.
307* After the season 3 premiere of ''WesternAnimation/RickAndMorty'' revealed that Rick was obsessed with the Szechuan dipping sauce UsefulNotes/McDonalds released to promote ''WesternAnimation/{{Mulan}}'' back in 1998, fans started clamoring for [=McDonald's=] to re-release the sauce. Not only did they oblige and release it in limited release in October 2017 followed by a wide release four months later, but [=McDonald=]'s even sent series creator Creator/JustinRoiland a case of the stuff before anyone else got it!
308* ''WesternAnimation/SpongeBobSquarePants'': Many young clarinet players picked up the instrument thanks to Squidward.
309* When the full trailer for ''WesternAnimation/StarTrekLowerDecks'' season 2 aired, one of the scenes showed Boimler talking to a collector plate of ''Series/StarTrekVoyager''[='s=] Tom Paris. Immediately after, it was revealed they thought ahead and ''made'' those very collector plates.
310* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' created a craze for unicorn-themed media, as its protagonist was a unicorn. The craze still goes on to this day. ''WesternAnimation/DespicableMe1'' may have also contributed to the unicorn craze, as one scene features Agnes winning a stuffed unicorn from a carnival. Replicas of this specific stuffed unicorn are a popular prize at carnivals and state fairs.
311[[/folder]]
312
313[[folder:Other]]
314* [[http://www.founditemclothing.com/ Found Item Clothing]] re-creates T-shirts seen in films, and [[http://www.abbyshot.com AbbyShot Clothiers]] has more or less devoted its entire line of clothing to faithfully reproducing coats and others apparel originally seen in [[ImpossiblyCoolClothes video games, movies, and anime]].
315* University of Nevada hoodies were sold out from the university online store after pictures of [[http://en.wikipedia.org/wiki/Nevada-tan Nevada-tan]] surfaced. Nevada-tan is the Internet nickname for a Japanese girl who murdered a classmate in 2004, deriving from a widely published photograph of her wearing a University of Nevada hoodie. The store temporarily withdrew the hoodie from sale after learning the reason for the sudden increase in demand.
316* A bizarre example of the news having this effect: following the revelation that former Russian spy Alexander Litvenenko had been poisoned with the radioactive element polonium, a Polish restaurant in Sheffield called Polonium saw its bookings skyrocket. This is probably the result of Sheffielders Googling the element and finding the website of the restaurant in the search.
317* When Chef Paul Prudhomme first introduced his famous recipe for blackened redfish, it became so popular ''that it put the redfish on the endangered species list''.
318* Major sports events every year inspire thousands of people to discover their inner athlete and suddenly take up said sport, only to give it up a couple of weeks after said event is over. Happens very prominently with less popular recreational sports such as tennis (try getting a public court when Wimbledon is on in the UK).
319* U.S. presidents have been known to affect demand for things they like, but John F. Kennedy was one of the biggest. When word circulated that he could read 1600 words per minute, attendance in speed-reading courses went up. He also listed ''Literature/FromRussiaWithLove'' as one of his favorite books in ''Magazine/{{Life}}''; it instantly became a best-seller, piqued American interest in ''Literature/JamesBond'', and ensured that it would be [[Film/FromRussiaWithLove the next Bond novel adapted to film]]. He's even credited with "killing the hat" by not appearing in public with one, although that one's apocryphal -- the hat was already in decline since the early-mid 1940s (almost two decades before he became President),[[note]]This was partly because of wartime restrictions and rising post-war use of cars[[/note]] and the hat would remain a standard piece of menswear until around 1965-67. Furthermore, he ''did'' wear a top hat to his inauguration (only to take it off for his "Ask Not" speech).
320* An inversion ocurred with the constant use of double-breasted blazers by bankers and financiers between the 1980s and 2000s. After the 2008 crisis, the jacket's reputation went from "cool gangster suit" to "corrupt banker suit", and thus demand evaporated overnight... before it saw a revival of sorts about a decade later.
321** Formal clothes in general fell victim to the crisis and its link to Wall Street men. Furthermore, the fact tech entrepreneurs only wore casual clothes (blazers being their most "formal" piece of attire) led most companies to drastically relax or even completely ditch their dress codes, to the point many places discourage the use of formal clothing in favor of a more casual set-up known as the "Midtown Uniform".
322* For a number of years now, [[http://www.thinkgeek.com/ thinkgeek.com]] has been {{defictionaliz|ation}}ing its most popular AprilFoolsDay jokes. Such products include the [[https://noveltystreet.com/thinkgeek-8-bit-pixel-tie 8-bit tie]], the [[https://www.destructoid.com/grow-your-own-1up-mushroom/ Grow Your Own 1-Up Mushroom,]] the [[https://www.youtube.com/watch?v=DC5R1FIFDGQ Personal Soundtrack T-Shirt]] and [[https://noveltystreet.com/thinkgeek-canned-unicorn-meat Canned Unicorn Meat.]] But perhaps their most famous was the [[https://www.gamestop.com/home/bedroom/bedding/products/star-wars-tauntaun-sleeping-bag/11099465.html Tauntaun Sleeping Bag]], named after the creature from ''Film/TheEmpireStrikesBack'' whose stomach Han and Luke ''slice open'' to hide inside for shelter on Hoth.
323---> ''Classic Franchise/StarWars sleeping bag simulates the warmth of a Tauntaun carcass''
324* The 2010 [[UsefulNotes/TheWorldCup FIFA World Cup]] (as well as the FIFA Confederations Cup the previous year) had ''audibly'' made the Vuvuzela pretty popular among spectators.
325* Athletes have been known to influence hairstyles:
326** The increase of the popularity of men suffering from male pattern baldness shaving their heads could be traced to the decision of basketball legend UsefulNotes/MichaelJordan shaving his head for that reason.
327** In Brazil, soccer player Ronaldo also shaved his head. He also gave the world [[http://copa3x4.files.wordpress.com/2010/05/ronaldo-cascao.jpg this horrible haircut]] (compared to [[https://web.archive.org/web/20171104081908/http://i40.tinypic.com/27y1lig.jpg Cascão/Smudge]] of local comic strip ''ComicBook/MonicasGang''), which inspired children to imitate him.
328** In the U.K., David Beckham's hair was the source of many such fashions, including the mohawk he wore in the 90s, his skinhead look in the early 2000s and his undercut in the 2010s.
329* On February 2, 2011, knitting blogger Stephanie Pearl-[=McPhee=] posted [[http://www.yarnharlot.ca/blog/archives/2011/02/02/mine_mine_all_mine.html an entry]] about her wonderful new mittens, which she had knitted from mawata (silk hankies) obtained from Blue Moon Fiber Arts. By [[http://www.yarnharlot.ca/blog/archives/2011/02/04/mawata_wonders.html February 12,]] Blue Moon's page of roving (fibers for spinning) had no entry for mawata, only a plaintive note urging eager knitters to be patient while they caught up with "overwhelming demand".
330** This is actually fairly common -- in the same vein as Being Farked, one can be "Harlotted"; a yarn or pattern Stephanie uses becomes an incredibly in demand product.
331* [[http://www.amazon.com/Mountain-Three-Wolf-Short-Sleeve/dp/B002HJ377A Three Wolf Moon]]: This ordinary (albeit cool-looking) T-shirt is probably one of the most popular products on all of Amazon.com, and it's all thanks to one parody review.
332* When [[UsefulNotes/NationalBasketballAssociation NBA]] player Jason Collins [[StraightGay came out the closet]]--becoming the first openly gay athlete in one of America's "Big Four" major leagues--he revealed that the reason he wears the number 98 is to commemorate Matthew Shepherd, a gay college student whose brutal murder in 1998 led to the passing of hate crime laws in the US. After making that announcement, his Brooklyn Nets jersey became the biggest seller on the NBA's website.
333* Guns:
334** The quickest way to get civilian gun enthusiasts interested in a gun is for the military and law enforcement to start using it. The Beretta 92F kicked off the "Wonder Nine" boom in the mid-'80s when the US Armed Forces replaced the [[TheWorkhorse venerable]] Colt M1911 pistol (which, as its name suggests, has been in service since before UsefulNotes/WorldWarI) with a military version of it, designated the M9 pistol, as their standard sidearm. Glock pistols, too, caught on with civilians thanks to Glock's program in the late '80s giving police departments seeking to upgrade from their revolvers large discounts on their guns, as well as the fact that the gun's light weight, high ammo capacity, and accuracy made it attractive to law enforcement in the first place. The Barrett M82 rifle was originally created by a single guy as a dare to create a [[{{BFG}} .50 BMG rifle]], a weapon that turned out to have a lot of military utility as a long-range anti-materiel rifle, and after its adoption by the US military as the M107 rifle, many gun stores will typically have one lovingly displayed in the middle of the store the way a Chevrolet dealership might display a Corvette in its showroom.
335** The above, however, wound up inverted for a long time by the AR-15, the civilian version of the M16 rifle, whose status as the US military's infantry rifle was balanced out and then some by the ([[ScrewedByTheNetwork undeserved]]) [[ReliablyUnreliableGuns terrible reputation]] it earned in [[UsefulNotes/TheVietnamWar the jungles of Vietnam]]. Between that and the tightening of American gun laws in the '80s and '90s, civilian interest in the AR-15 was mainly limited to hardcore military enthusiasts. This was turned around, however, in the 2000s during UsefulNotes/TheWarOnTerror. By that time, most of the flaws of the M16 and its short-barreled version, the M4 carbine, had been worked out, while the Federal Assault Weapons Ban expired in 2004, allowing for the widespread sale of semiautomatic rifles in most of the country. The AR-15, identified with American soldiers fighting insurgents in Afghanistan and Iraq, exploded in popularity and became an enduring symbol of American gun culture.
336** A [[http://www.cracked.com/personal-experiences-2367-4-things-you-learn-behind-counter-gun-store.html morbid version]] of this: whenever a high-profile mass shooting occurs in the United States, not only do gun sales typically go up, but sales of the specific model of gun used in the shooting skyrocket even further. Sales of the Glock 19, for instance, shot up after a would-be assassin used one to badly wound Representative Gabrielle Giffords (of Arizona's 8th congressional district) and kill six others at a campaign rally, as did sales of AR-15-style rifles after the Sandy Hook Elementary School killer used one. Even gun accessories are subjected to this, as happened when "bump stocks", a modification that uses a semiautomatic rifle's recoil to effectively turn it into an automatic weapon, [[https://www.yahoo.com/news/gun-stores-selling-bump-stocks-153911597.html sold out at stores across the country]] after the Las Vegas concert killer used them on his rifles. The reason for this is fear that incoming gun control legislation will make it impossible to get that weapon down the line, leading many gun enthusiasts to feel that they need to get one as soon as possible. Indeed, the connection between left-wing electoral success and surges in gun sales -- and, conversely, right-wing electoral success and hard times for the firearms industry[[note]][[UsefulNotes/AmericanGunPolitics In the US]], gun control is generally held to be a left-wing issue, and opposition to such is generally held to be a right-wing issue. There are exceptions in both directions, of course.[[/note]] -- is [[https://finance.yahoo.com/news/obama-great-gun-business-trumps-terrible-163923519.html so well-known]] that a (possibly tongue-in-cheek) conspiracy theory claims that gun and ammo manufacturers are secretly backing ineffectual anti-gun politicians and activists in order to invoke this, exploiting fear of gun control to drive sales.
337* In 2006, Britain's already scandal-hit Deputy Prime Minister John Prescott found himself in even bigger trouble when he treated himself to an afternoon off to enjoy a game of croquet. Bad news for him, as it ultimately cost him his grace-and-favor mansion, but good news for manufacturers of croquet sets which suddenly came into greater demand than they had for decades.
338* Creator/OJSimpson's infamous chase down the UsefulNotes/LosAngeles freeway in a white Ford Bronco saw sales of that vehicle skyrocket by seven thousand in the following year, despite it being a fairly primitive model of SUV compared to Ford's Explorer and other modern, four-door vehicles. It took until 2021 for Ford to do this, but the Bronco was a ContinuityReboot that paid homage to the original 1965-1996 model, and shared no mechanicals with it, and was smaller.
339* The shooting of Trayvon Martin by George Zimmerman led to a spike in sales of Skittles candy. Martin was holding a bag of Skittles when he was shot, and as such, Skittles [[IconOfRebellion became a popular symbol at the protests]] that eventually coalesced into the UsefulNotes/BlackLivesMatterMovement.
340* When Nissan came up with the Skyline GT-R line of sports cars based on the Skyline luxury car range, it was not officially sold in Western markets. However, the likes of ''VideoGame/GranTurismo'' and ''Film/TheFastAndTheFurious'' among others spurred so much mainstream interest in the "Godzilla" that grey-market importers stepped in to cater to the demand. One such importer was Motorex, who supplied the GT-R used by Paul Walker's character in the first film. Nissan eventually took notice and developed the R35 GT-R, first conceptualised in 2001 and [[SavedFromDevelopmentHell released in 2007]]. The R35 [[DivorcedInstallment branched off]] from the mainline Skyline range, as part of its ContinuityReboot.
341* Because figure skater Yuzuru Hanyu is a Japanese national (and international) darling, he's created an effect referred to as "Hanyueconomy". Fans would follow him to competition, booking hotels and boosting the service industry. Dedicated [[FanCommunityNickname Fanyus]] track down the brands he wears and uses, buys up merchandise that he sponsors/has his face on, so on and so forth. Anything that he's seen using sells out at an incredible speed.
342* The Tama Zoo in western Tokyo, Japan getting in koalas as a gesture of goodwill from Australia caused a surge in demand for media about koalas, which lead to the productions of ''Anime/AdventuresOfTheLittleKoala'' and ''Anime/TheNoozles''.
343* Sales of Timex watches with the "Indiglo" backlight skyrocketed after the 1993 bombing of the World Trade Center, where an office worker used the light to guide a group down 40 unlit flights of stairs. The incident also increased the reputation of the Timex brand, which had for years been considered cheap and inferior compared to more pricey models by other companies.
344* A famous {{Urban Legend|s}} about a chemical [[PuttingThePeeInPool that makes urine in a swimming pool]] turn cloudy red or purple has led many pool owners to ask retailers selling pool cleaning supplies to buy this item. No such chemical actually exists but this doesn't stop the customers from asking.
345* When UsefulNotes/BarackObama's wife Michelle and daughters Malia and Sasha wore J.Crew clothing to his inauguration in 2009, the preppy clothing retailer's website [[https://archive.nytimes.com/bits.blogs.nytimes.com/2009/01/21/seeking-obama-fashions-visitors-crash-j-crews-web-site/ crashed]] from the surge in traffic, with Michelle's green leather gloves and Malia and Sasha's respective blue and pink wool coats and velvet ribbon belts being particularly popular. J.Crew was quick to capitalize on the connection, noting that these outfits were specially designed for the Obamas. Isabel Toledo and Jason Wu, the respective designers of Michelle's day and evening dresses from the inauguration, also got a surge of attention.
