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.
* 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.
* ExpositoryThemeTune: Many of their shows had this so children wouldn't be lost to the point where they were each about a minute and a half long.
* {{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.
* 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
* SurroundedByIdiots: Mostly the villains.
