"Fraggle Rock" debuted in 1983 as one of the first shows involving the collaboration of Henson International Television (HiT Entertainment from 1989), the international arm of Jim Henson Productions. The co-production brought together British regional ITV franchise-holder Television South (TVS), CBC Television (Canada), and U.S. pay-TV service Home Box Office and Henson Associates (later Jim Henson Productions). Filming took place on a Toronto soundstage (and later at Elstree Studios, London). The avant-garde poet bpNichol worked as one of the show's writers. In the early days of development, the script called the Fraggles "Woozles" pending the devising of a more suitable name.
