Sid Krofft and Marty Krofft, known as The Krofft Brothers and born as Cydus and Moshopopoulos Yolas, were a Canadian sibling team of television creators, writers and puppeteers. Through their production company, Sid & Marty Krofft Pictures, they made numerous children's television and variety show programs in the U.S., particularly in the 1970s, including H.R. Pufnstuf, Land of the Lost, and Sigmund and the Sea Monsters. Their fantasy programs often featured large-headed puppets, high-concept plots, and extensive use of low-budget special effects.

H.R. Pufnstuf is an American children's television series created by Sid and Marty Krofft. It was the first independent live-action, life-sized-puppet program, following on from their work with Hanna-Barbera's program The Banana Splits Adventure Hour. The seventeen episodes were originally broadcast Saturday from September 6, 1969, to December 27, 1969. The broadcasts were successful enough that NBC kept it on the schedule as reruns until September 4, 1971. The show was shot at Paramount Studios and its opening was shot at Big Bear Lake, California. Reruns of the show returned on ABC Saturday morning from September 2, 1972, to September 8, 1973, and on Sunday mornings in some markets from September 16, 1973, to September 8, 1974. It was syndicated by itself from September 1974 to June 1978 and in a package with six other Krofft series under the banner Krofft Superstars from 1978 to 1985. Reruns of the show were featured on TV Land in 1999 as part of its Super Retrovision Saturdaze Saturday morning-related overnight prime programming block and in the summer of 2004 as part of its TV Land Kitschen weekend late-night prime programming block, and it was later shown on MeTV from 2014 until 2016.
