In the 1970s, Sid and Marty Krofft were to live-action children's TV what Creator/HannaBarbera was to animation. Their first series, ''Series/HRPufnstuf'', debuted in 1969 and established their production style: fantastic creatures, usually with thick fur or oversized heads; a "stranger in a strange land" motif; fearsome but comical villains, and clever wordplay and visual gags. Of course, not all of those elements appeared in all Krofft shows. And [[WhatDoYouMeanItWasntMadeOnDrugs what on earth do you mean, their work wasn't made on drugs?]]

Other Krofft series included ''Series/TheBugaloos'', ''Land of the Lost'' (both the [[Series/LandOfTheLost1974 1974 original]] and its [[Series/LandOfTheLost1991 1991 revival]]), ''Series/{{Lidsville}}'', ''Series/FarOutSpaceNuts'', ''Series/SigmundAndTheSeaMonsters'', ''Series/ElectraWomanAndDynaGirl'', ''[[Series/BradyBunchSpinOffs The Brady Bunch Variety Hour]]'', ''Series/DCFollies'', and the infamous ''Series/PinkLadyAndJeff''. Before producing series on their own, the Krofft brothers designed the costumes for Hanna-Barbera's ''WesternAnimation/TheBananaSplits''.

Possibly the most interesting piece of Krofft history was their 1973-77 lawsuit against the UsefulNotes/McDonalds corporation. When it couldn't get the Kroffts to license ''H.R. Pufnstuf'' for use in [=McDonald's=] commercials, the hamburger chain blatantly plagiarized ''Pufnstuf'' to create [="McDonaldLand"=] in 1971.

During the mid-1970s, they had a theme park in downtown Atlanta, called ''The World of Sid and Marty Krofft'', notable for being the world's first indoor amusement park; it closed within six months. The facility that housed it, the Omni International, was later bought by Ted Turner and became the new HQ for Creator/{{CNN}}, the CNN Center.

Bob Odenkirk and David Cross' ''Series/MrShow'' parodied the WhatDoYouMeanItWasntMadeOnDrugs nature of their productions in a sketch about Sam and Kriminy Kraffft, a pair of producers showing the unaired pilot for their show ''The Altered State of Drugachusettes''.

In 2015, their Edutainment series for Nickelodeon ''Mutt & Stuff'' became an unexpected hit, resulting in a 40 episode first season order and the commissioning of a brand new special that will see the Mutt & Stuff cast visited by the Pufnstuf cast. The mind boggles.
!!''Tropes Associated with Sid & Marty Krofft:''

* AmazingTechnicolorPopulation
* AndNowForSomethingCompletelyDifferent: They seemed to try just this every few years or so. For example, after a string of high-concept fantasy series, but the mid-1970s, they made a transition to producing campy variety series; this lasted up through the 1980s, when they made another switch to more comedy-based programs.
* AndStarring:
** ''Series/HRPufnstuf'': And starring Billie Hayes as Witchiepoo
** ''Series/LandOfTheLost'': And starring Spencer Milligan as Rick Marshall
** ''Series/TheLostSaucer'': Larry Larsen as The Dorse
** ''Series/FarOutSpaceNuts'': Creator/PattyMaloney as Honk
** ''Series/TheKrofftSupershow'', ''Series/TheKrofftSuperstarHour'', and ''DC Follies'': And featuring the magic of the Krofft Puppets
* AuthorAvatar: The second season of ''Series/DCFollies'' featured puppet caricatures of Sid and Marty, who were usually featured during the episode's closing, either arguing with each other, or bantering with the other puppets.
* BadBadActing: Many of the Kroffts' later shows suffer from this. ''The Krofft Supershow'' alone is chock-full of it.
* BigDamnMovie: ''Pufnstuf'' (1970), ''Land of the Lost'' (2009). Interestingly, both were handled by Creator/{{Universal}}, which had nothing to do with any of their series; supposedly, reboots of ''Pufnstuf'', ''Lidsville'', and ''Sigmund'' are in the works, with different studios, including [=DreamWorks=] and Sony.
* TheCastShowoff: Most Krofft shows have at least one character or actor who falls into the category.
* CoolCar: A number of them in various series, but Wonderbug probably tops the list (though his alter-ego, Schlepcar, is TheAllegedCar).
* DoesThisRemindYouOfAnything: Some of the Krofft shows obviously draw heavy (perhaps a little too heavy) influence from other shows, such as:
** ''Series/SigmundAndTheSeaMonsters'': Sid Krofft and producer Si Rose admit that Sigmund's family is pretty much copied after [[Series/AllInTheFamily the Bunker family]], with Big Daddy Ooze a sea monster caricature of Archie, and Sweet Mama as Edith.
** ''Series/FarOutSpaceNuts'': Sid admits that this show is essentially Creator/LaurelAndHardy [[RecycledInSpace in space]].
** ''Series/PryorsPlace'': Basically ''Series/SesameStreet'' in UsefulNotes/LosAngeles instead of [[BigApplesauce New York City]]; Richard Pyror playing various different color residents instead of Gordon, Susan, Bob, and Mr. Hooper; a half-hour plot instead of an hourlong scene interrupted by various different skits and inserts, and a LaughTrack.
** ''Series/DCFollies'': TransatlanticEquivalent to ''Series/SpittingImage''.
** As of 2012, Marty Krofft has said that he and Sid are in the process of starting up a new educational series that they flat-out said will be their version of ''Sesame Street''.
* EasyAmnesia: Just about every single Krofft show has an episode like this.
* {{Expy}}: ''DC Follies'' is basically an American ''Spitting Image''.
** And ''Wonderbug'' is a Saturday morning ''HerbieTheLoveBug'' and live-action ''SpeedBuggy''.
* LargeHam: See TheCastShowoff above.
* LaughTrack: When the Kroffts brought on veteran producer Si Rose to help them with ''H.R. Pufnstuf'' (and he eventually executive produced a majority of their earlier shows), Rose persuaded them to use a laugh track, reasoning that a funny show without a laugh track was a handicap. The Kroffts were skeptical at first, but eventually agreed, and as such, most Sid and Marty Krofft productions (save for both versions of ''Series/LandOfTheLost'', since they were more dramatic) contain one.
* {{Lying Creator}}s:
** Up until TheNewTens, both Sid and Marty were said to be fifth generation puppeteers, both of whom continued the family legacy of puppeteering from their father, who had been the owner/manager of the Krofft Theatre in Athens, Greece (where Sid was born), resulting in their names being changed from Cydas and Marshopopoulos Yolas to Sid and Marty Krofft. Afterwards, both Sid and Marty finally confessed in an interview that their father was not a puppeteer, and was, in fact, a clock salesman, and that the story of them carrying on their father's work was concocted by their then-publicist.
** Around the same time, Marty also finally admitted that (after years of fan speculation) yes, the title ''Series/HRPufnstuf'' was, indeed, a blatant reference to drugs. Marty still swears, however, that he and Sid have never done any drugs while creating their shows, and claims the idea behind the name came more from a childish sense of humor and wanting to see if they could get away with it and [[GettingCrapPastTheRadar slip it past the network censors.]] Considering Creator/{{NBC}} thought the title was a reference to a powder puff rather than reefer smoking indicates they pulled it off.
* NoCelebritiesWereHarmed: Most Krofft shows have characters like this; some specific examples include the Ooze family from ''Series/SigmundAndTheSeaMonsters'' being modeled after [[Series/AllInTheFamily the Bunkers]].
** ''DC Follies'' alone takes it up a notch, as the entire cast of the show (aside from Fred Willard as himself) were life-sized puppet caricatures of politicians and celebrities who were in the news at the time.
* NonHumanSidekick: A number of their human characters have one.
* OurDragonsAreDifferent
* PeopleInRubberSuits: The Kroffts were really the first to try this, before Disney even had walkaround characters at its theme parks.
* PuppetShows
* TheRevival: They've had many attempts at reviving their own work for newer generations, but haven't been too successful at it. Only two revivals of ''Series/LandOfTheLost'' saw the light of day (a new series in 1992, which wasn't as successful as the original, and the BigDamnMovie of 2009, that was a trainwreck); throughout the 2000s, new versions of ''Series/ElectraWomanAndDynaGirl'' and ''Series/FamilyAffair'' were in the works (the latter had nothing to do with the original, but had obvious connections with cast member Johnny Whitaker), and presently, movie remakes of ''Series/HRPufnstuf'', ''Series/{{Lidsville}}'', and ''Series/SigmundAndTheSeaMonsters'' are in the works.
** It perhaps is not surprising that the sudden success of their 2015 Nick series ''Mutt & Stuff'' has kickstarted things, with a Mutt & Stuff/Pufnstuf crossover promised for early 2016. Meanwhile Amazon's 2016 Pilot Season will feature the pilot for a brand new ''Sigmund'' series.
** In Comic Con 2015 the Kroffts revealed a Bugaloos remake from the Bugaloos and they are communicating with a cable network so to speak, Also they hinted Cyndi Lauper would play Benita Bizarre, They also are looking into a remake of Lidsville
* ShootTheMoney: Mainly because networks gave them rather small and meager budgets, while their characters and settings cost ''millions'' of dollars to create.
* SurroundedByIdiots: Mostly the villains.
* StopTrick
* UnintentionalPeriodPiece: At least Sid thinks so.
* WordOfDante: Many have said that the Kroffts sued [=McDonald's=] for ripping off ''H.R. Pufnstuf'' with their [=McDonaldLand=] concept, when this is actually false. In a 2000 interview for the Archive of American Television, Sid and Marty said that [=McDonald's=] commissioned them to create a [=McDonaldLand=] for their commercials, which they began doing, then halfway through the creating process, [=McDonald's=] told them they decided to pull the plug on the project, so the Kroffts stopped their art department, and that was that... until the [=McDonaldLand=] commercials began popping up on television a few months later, without the Kroffts' knowledge, which led to the lawsuit.
* YouLookFamiliar: The Kroffts had a tendency to use some of the same actors in various different shows of theirs. For example:
** Billie Hayes played Witchiepoo in ''H.R. Pufnstuf'', then later played Weenie the Genie in ''Series/{{Lidsville}}''.
** Lennie Weinrib did a number of character voices (most notably Pufnstuf) and also played the titular Magic Mongo from ''Series/TheKrofftSupershow''.
** Jack Wild was immortalized as Jimmy from ''H.R. Pufnstuf'', but he also portrayed himself in the special ''The World of Sid & Marty Krofft at the Hollywood Bowl'' and an episode of ''Sigmund and the Sea Monsters''.
