Hill remained mostly with the BBC through to 1968, except for a few sojourns with ITV and ATV stations between 1957 and 1960 and again in 1967. In 1969, his show moved from the BBC to Thames Television, where it remained until its cancellation in 1989, with an erratic schedule of one-hour specials. The series showcased Hill's talents as an imaginative writer, comic performer, and impressionist. He may have bought scripts from various comedy writers, but if so, they never received an onscreen credit (some evidence indicates he bought a script from one of his regular cast members in 1976, Cherri Gilham, to whom he wrote from Spain, telling her he was using her "Fat Lady" idea on the show in January 1977).
