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.

[4] Sid Krofft became a popular puppeteer who worked in vaudeville[citation needed] and was a featured player with the Ringling Bros. and Barnum & Bailey Circus.

His father joined him on tour in Paris while Marty stayed in New York, where he began using his older brother's puppets to earn money by staging performances.

By the 1950s, the Krofft brothers were working together, and in 1957, they developed Les Poupées de Paris, a puppet show with more mature themes.

[citation needed] After designing the characters and sets for Hanna-Barbera's The Banana Splits (NBC, 1968–1970), the Kroffts' producing career began in 1969 with the landmark children's television series H.R.

Featuring a boy who has been lured into an alternate fantasy world and can never escape, the team also established a storytelling formula to which they would often return.

[8] Their "camp" popularity stems largely from their shows' low-budget production values, the often surrealistic feel of many of the programs, and the uniquely "70s" style of music and design.

[8] The Kroffts have occasionally departed from their formula while making new programs, such as on Pryor's Place (1984) and the political puppet satire show D.C. Follies (1987).

They have attempted to update some of their classic series for a younger generation, including new versions of Land of the Lost, Electra Woman and Dyna Girl, H.R.
