Show to their channel. Production was handled by Thames Television shortly after its return in 1968, with Corbett presenting the programme until he was forced to retire in 1976, with his son Matthew Corbett presenting the programme until its conclusion in 1992, when Thames lost its franchise. Format The Sooty Show featured three different formats during its broadcast history: two created by Harry Corbett, the programme's creator; and the third by Harry's son, Matthew Corbett. The first format, used from the programme's premiere in 1955, functioned in the manner of a cartoon short. In this arrangement, Harry would detail a scenario to viewers that Sooty was undertaking, that would often go wrong and cause chaos, often for Harry. The plots devised for these episodes were influenced by societal values, current events and the development of new technologies, tailored towards amusing young children, and made use of slapstick humour, including the use of cream pies and water.

The third format used by the programme was introduced by Matthew in 1981, later becoming a staple for all future programmes in the Sooty franchise. Under the new format, Matthew discontinued the use of a studio audience and comedic sketches, in lieu of a sitcom format focused on a single misadventure, with himself, Sooty, Sweep and Soo sharing a suburban house together. Elements of the previous format, such as guest stars and music, were retained, with narration added in for scenes focused entirely on the puppets; story-telling was also retained, but phased out over the 1980s. The new format included the use of educational elements in some stories, and the creation
