Question: Did The Secret Service win any awards? Passage:The Investigator was Gerry Anderson's first puppet production since The Secret Service (1969), the last Supermarionation series to be made by his former company Century 21 Productions. Having gone on to make the live-action series UFO and The Protectors, neither of which were made specifically for children, Anderson wanted to create something new for the younger audience and devised The Investigator as the template for a new Supermarionation programme, intending to pitch it to American network NBC in the hope that it would commission a series. The pilot was planned by Anderson, his wife Sylvia and their long-time business partner Reg Hill. Written by Sylvia from a story by Shane Rimmer, it was funded by private venture capital and produced by off-the-shelf company Starkits between The Protectors and a planned second series of UFO (which was later made as ).
