Some series are set in the present, or TwentyMinutesIntoTheFuture, or they're meant to have a sort of timelessness to them (which make it awkward whenever someone brings out [[TechnologyMarchesOn a cassette tape or a payphone]]), or else they're set in [[PeriodPiece the distant past]], so far back that no-one who was alive at that time would be alive to shout "Hey! That's not how it was back in my day!"

Then there are these pieces. Maybe they wanted to avoid certain things from today's society, like modern technology or the Internet, that they didn't have when they were a kid. Maybe the author was looking back to the "good ol' days". For one reason or another, they've chosen to set their show a couple decades back.

Now, just slapping a "June 5th, 1976" on an establishing shot isn't enough. The show's time period has to be readily evident. If it's set in [[TheSixties the 1960s]], they should listen to The Beatles and protest the Vietnam War. If it's set in [[TheSeventies the 1970s]], some mention of disco and classic rock should come up. If it's set in [[TheEighties the 1980s]], everyone should be blowing out their hair and wearing neon. If it's set in [[TheNineties the 1990s]] get the idea. It doesn't necessarily need to be TheThemeParkVersion of its decade, but it should be pretty blatant.

Note that this differs from a PeriodPiece because of the nostalgia factor; if there's an obvious reason for the series to be set at a certain time, then it becomes a period piece. For example, ''Film/TheGreatGatsby'' is set in the 1920s because it's based on a novel written at that time (in particular one that delved deeply into the pop culture of the time, making it difficult to set in other time periods). Meanwhile, the film ''Film/FrostNixon'' is based on events from the 1970s, and so there's less of a nostalgic factor in the decision to set it in that time so much as historical accuracy. On the other hand, ''Literature/HarryPotter'', despite being set in the 1990s, wouldn't qualify because there's nothing nostalgic about the books or really any indication of the decade it's in beyond the dates. We can't know for sure that the author is setting a work at some point in time because they're feeling nostalgic, but unless the work is based on something else (historical events or a work from that time period), then nostalgia is a logical assumption. In general, if you can picture the author of a work writing the script, and then deciding last minute to set it in such-and-such time period, then it counts as this trope.

Furthermore, as a rule of thumb, the series' main creators should have been alive when the series is being set (More or less; it's possible to be nostalgic for your parents' era as well). It can't be too recent; generally, anything set in the 21st century is a no-go. On the other hand, if it's too old, it becomes less nostalgic and more of a period piece; for example, something set in [[TheRoaringTwenties the 1920s]] today is now considered a period piece. A good rule of thumb is anything set less than [[TwoDecadesBehind 20]] or more than 50 years ago does not qualify; as of 2010, [[TheSixties the 1960s]] have slipped into period piece territory, and [[TheNineties the 1990s]] have fallen into this.

Sub-trope of PeriodPiece. Compare {{Retraux}}, which is when the series is meant to ''look'' like it's from a time period, which has its own nostalgic value. May relate to RomanticismVsEnlightenment as another reason to set a piece in an earlier time period. Has nothing to do with the video game ''VideoGame/{{Nostalgia}}'', or ''WebVideo/TheNostalgiaCritic'', or any of the many [[FollowTheLeader similar critics]]; the trope for that is CausticCritic.
!!Examples (in order of the period when they're set):

[[folder: Anime and Manga]]
* ''Anime/SazaeSan'' began in 1969 and was dated even then. The manga began in the '40s and it shows. The anime has been [[LongRunners running non-stop]] and is certainly this more than ever. It's one of the top 5, if not the number 1, anime in Japan and is seen as a quaint story about a Showa-era {{housewife}} and her family.

[[folder: Film ]]

* Between 1944 and 1948, Creator/JudyGarland starred in a trio of nostalgia musicals for MGM:
** ''The Harvey Girls'' is a 1946 musical about the Harvey House restaurants that followed the railroads west and the women who worked as servers there, set in TheGayNineties.
** ''In The Good Old Summertime'' is a 1949 musical remake of ''Film/TheShopAroundTheCorner'', also set in TheGayNineties. It features a cameo appearance by 3-year-old Liza Minelli in the last shot. Ms. Minelli, of course, is the daughter of Judy and the director of the first movie in this informal trifecta.
** ''Film/MeetMeInStLouis'', made by Vincente Minelli and Creator/JudyGarland in 1944, looks back with affection on the St. Louis of 1904. While most of the filmmakers were looking back to their parents' era, the film was based on the short stories and novel of Sally Benson, who wrote from her own childhood experiences.
* ''Film/MaryPoppins'' comes from Walt Disney's admiration for the Edwardian Era. The books are set in the 1930s but the film moves the setting to the early 1900s. There seems to be no reason for the change other than the nostalgia and Walt's particular fondness for the era.
* ''Film/{{The Roaring Twenties|1939}}'' is a 1939 film that looks back on TheRoaringTwenties, ExactlyWhatItSaysOnTheTin -- though it begins in 1918, at the very end of The Great War.
* The 1980s ''Franchise/IndianaJones'' movies were set before UsefulNotes/WorldWarII. The [[Film/IndianaJonesAndTheKingdomOfTheCrystalSkull fourth one]], however, moves into PeriodPiece territory.
* The 1971 film ''Film/SummerOf42'' was screenwriter Herman Rauscher's almost-autobiographical look back at his own summer vacation of 29 years previous.
* 1978's ''Film/{{Grease}}'' was this to the 1950s.
* ''Film/SchoolTies'' is set in the 50s, most obviously evidenced by the tame rock 'n' roll that plays in the film, which is treated as rowdy and wild.
* ''Film/CryBaby'' is Creator/JohnWaters second foray into nostalgia (see below), being a look back from 1990 to the Baltimore of 1954.
* ''Liberty Heights'', released in 1999 and set in 1954, is the fourth and final of the "Baltimore Films" by Barry Levinson (see below); all, like fellow Baltimore native Creator/JohnWaters, were based either on his own memories or those of his family & friends of the time.
* ''The Lords of Flatbush'', a 1974 film starring Creator/SylvesterStallone and future [[Series/HappyDays Fonzie]] Creator/HenryWinkler, looks at 1958 Brooklyn working-class kids.
* ''Film/StandByMe'' is set in 1959 and attempts to mark the transition from TheFifties to TheSixties--from Innocence to Experience--reflecting the coming of age of four Oregon youths (and the youths of director Rob Reiner and author Creator/StephenKing).
* ''Film/{{Diner}}'', released in 1982 and set in 1959, is the first of the "Baltimore Films" by Barry Levinson.
* ''Film/AcrossTheUniverse'', being set in the '60s and made in 2007, just barely qualifies as this.
* ''Film/AmericanGraffiti'' was made by Creator/GeorgeLucas in the '70s to look back on his adolescence; while this Oscar-nominated box-office success helped spark the explosion of nostalgia for TheFifties, and is practically the TropeCodifier for [[NothingButHits the all-star soundtrack]] that would accompany so many later nostalgia films, it is set specifically in September 1962.
* ''Film/{{Hairspray}}'', Creator/JohnWaters first PG film, is a surprisingly affectionate 1988 look back at Baltimore of 1962.
* ''Film/AnimalHouse'' was so influential on college students of the late 1970s and early 1980s that it is often overlooked for being nostalgic, but the 1978 film is clearly and specifically set in 1962, right down to the JFK homecoming float.
* The famous 1987 film ''Film/DirtyDancing'' is set in 1963.
* The much less famous 1979 film ''Film/TheWanderers'' is also set in 1963.
* ''Film/TinMen'', released in 1987 and set in 1963, is the second of the "Baltimore Films" by Barry Levinson.
* ''Film/{{Avalon}}'', released in 1990 and set over a period of decades from 1914 to the early 1960s -- thus both nostalgia and a PeriodPiece -- is the third of the "Baltimore Films" by Barry Levinson.
* ''More American Graffiti'', the 1979 sequel which Lucas produced but did not direct, and which was neither Oscar-nominated nor a box-office success, is set in four consecutive New Years Eves from 1964 to 1967.
* ''Film/TheHollywoodKnights,'' a 1980 film featuring early appearances by Creator/FranDrescher, Creator/TonyDanza and Creator/MichellePfeiffer, examines Halloween night, 1965, and the last night of a drive-in that is the favored hangout of the car club of the title.
* ''Dogfight'', a little-seen but critically-lauded film starring Creator/RiverPhoenix and Creator/LiliTaylor, was made in 1991 and set in 1965 and '66.
* ''Baby It's You'', Creator/JohnSayles ventures into nostalgia (he has also made more than one PeriodPiece); was made in 1983 and set in late 1966 and early 1967.
* ''Literature/TheOutsiders'' book was contemporary when it was written however the film adaptation was released in the 1980s. It's a harsh look at being a greaser in the '60s.
* Although it doesn't ''technically'' count (being based on a book written in 1971), the film version of ''Film/FearAndLoathingInLasVegas'' was made in 1998, at the height of 70s nostalgia.
* ''Film/AlmostFamous'' is Creator/CameronCrowe looking back at his own beginnings as a boy wonder rock journalist in 1973.
* ''Film/AnchormanTheLegendOfRonBurgundy'' is a 2004 film, set in the 70's mostly to get away with sexist jokes that wouldn't be politically correct today.
* ''Film/Anchorman2TheLegendContinues'' is set in the late 70s-early 80s, following suit.
* The ComingOfAgeStory ''Film/MyGirl'' is set in the mid 1970s and lets you know it - mood rings, Volkswagen vans, 70sHair, period-appropriate music etc.
* ''Film/DazedAndConfused'' is a 1993 film about high schoolers in '76, complete with Bicentennial references.
* ''Film/DetroitRockCity'' is a 1999 film about high schoolers in '78, complete with the disco/rock conflict of the time.
* ''54'' is a 1998 film based on the latter days of the infamous epicenter of disco, Studio 54.
* ''Film/TheLastDaysOfDisco'' is ExactlyWhatItSaysOnTheTin, made in 1998 and set in a FictionalCounterpart of Studio 54.
* ''Film/EverybodyWantsSome'' is a SpiritualSuccessor to ''Dazed And Confused'', looking nostalgically at a college in the summer of 1980.
* ''Film/BoogieNights'' explores the late '70s - early '80s porn scene from the perspective of 1997.
* ''Film/{{Adventureland}}'' is a downplayed version of this trope, set in the '80s and not really pushing the setting with the outfits except for certain "trendier" characters.
* Creator/AdamSandler's ''Film/TheWeddingSinger'' (1998), which uses the '80s setting for some lazy jokes and nothing else.
* While it is also a GenreThrowback, the movie ''Film/{{Super 8}}'' is still very much a love letter to the 80's.
* The 2006 British film, ''Film/StarterForTen'', is set in the '85-'86, a fact that it makes glorious use of for the soundtrack.
* ''Film/DonnieDarko'' was made in 2001 and set in 1988. It even seems to have some added film grain, making it [[{{Retraux}} look like it was made in '88]].
* The 2013 romantic comedy ''Film/TheToDoList'' is set in 1993, presumably to justify the heroine (an 18 year old, just graduated from high school) being ''completely'' sheltered about sex. The plot would not have been plausible in a post-internet era setting.
* The 2014 Liam Neeson film, ''Film/AWalkAmongTheTombstones'', is explicitly set in 1999, which doesn't change the plot too much, besides allowing the main character to be unfamiliar with computers and the "World Wide Web" (which he insists is a fad), and a lot of Y2K jokes.


[[folder: Literature ]]

* ''Literature/TheLovelyBones'', as well as its film adaptation, begin in 1973 and span a couple years.
* Creator/StephenKing's ''Franchise/TheDarkTower'' series has actually ''turned into'' this, being largely set in the '70s and publishing from 1982 to 2012.


[[folder: Live Action TV ]]

* Probably the TropeCodifier is ''Series/HappyDays'', which ran from 1974-84 and took place in the 1950s-60s. While a show set in the same time period would be considered a PeriodPiece nowadays, at the time when it was made it was very nostalgic.
** Creator/GarryMarshall followed it up with ''Series/LaverneAndShirley'' and several other, less well received nostalgia-com spinoffs.
* ''Series/HiDeHi'' is a 1980-88 British sitcom set in the Maplins holiday camp from 1959-60.
** From the same writers ''Series/DadsArmy'' ran from 1968-77, and is set during World War II.
* ''Series/MadMen'' plays this trope to a T, although it barely meets the "5 decades ago" requirement.
* ''Series/PanAm'' was this to the 60s before its cancellation.
* ''Series/OliverBeene'' was set in the 1960s, and used its time period to great effect, referencing {{Zeerust}} predictions for the present day of when it was broadcast that, of course, [[IWantMyJetPack time would prove completely wrong]].
* ''Series/TheWonderYears'' ran from 1988-93, and took place from 1968-73.
* The trope gets its name from ''[[Series/That70sShow That '70s Show]]'', which is set 22 years before it was originally made.
** By extension, it also gets its name from the lesser-known spin-off, ''Series/That80sShow''.
* ''Series/FreaksAndGeeks'' qualifies, being made in 2000 and set in 1980 (but really having more '70s nostalgia than the '80s).
* 2013 series ''Series/TheGoldbergs'' is set in the '80s and is largely biographical.
* The 1999 sitcom ''Hippies'', set thirty years earlier in 1969.


[[folder: Music ]]

* If any one performer could be said to have invented a "nostalgia genre" of rock, that man would have to be Creator/BobSeger. ''Night Moves,'' ''Main Street,'' ''Rock and Roll Never Forgets,''''Old-Time Rock and Roll,'' ''Against the Wind,'' ''Like a Rock'' ... practically all of his greatest hits evoke a desperately sharp, bittersweet longing for the past.
* Music/BillyJoel's 1983 album ''An Innocent Man'' is made up almost entirely of 1950s-style songs. The video for "Uptown Girl" keeps the theme as well.
* Deee-Lite's [[ music video]] for "Groove is in the Heart" is a classic '90s song, and features the singer and background dancers dressed up like characters from the '70s.


[[folder: Theater ]]

* Three of Broadway's biggest hits of the mid-20th century were ''Life With Father'', ''Film/IRememberMama'' and ''Theatre/TheMusicMan''; all were based on the childhood recollections of Clarance Day Jr., Kathryn Forbes and Meredith Wilson, respectively, and all were eventually made into motion pictures as well (though by the time Wilson's piece reached the stage it was almost a PeriodPiece).


[[folder: Western Animation ]]

* Creator/WaltDisney was enamored with the [[TheGayNineties 1890s]] (he was born two years after they ended, in 1901) and set many of his cartoons in that period, such as WesternAnimation/MickeyMouse's ''The Nifty Nineties'' and WesternAnimation/DonaldDuck's ''Crazy Over Daisy''. Even Donald's iconic outfit is a Gay Nineties throwback!
** Although ''Disney/LadyAndTheTramp'' doesn't quite meet the deadline (it was released in 1955, 65 years after the decade it was meant to invoke), it fits this trope in all other ways.
** 1946's ''Disney/MakeMineMusic'' features the animated short "Johnnie Fedora and Alice Blue Bonnet", which features horse-drawn carts that wouldn't be in style since the 1890s.
* ''WesternAnimation/TheIronGiant'' is set in the '50s.
