Input: Question: Which of the stop-motion animated works created by Firmin and Postgate had the most success? Passage:The popularisation of television broadcasting in the UK during the 1950s brought with it both new avenues for animation production and a shift in the demographic orientation of animation to the realms of children's programming. The year 1950 saw the premier of the long-running children's TV series Watch with Mother (1950–74) which would not include animation per se, but would feature several puppet-based segments (such as "Andy Pandy" and "Flower Pot Men") that would later become staples of British children's popular imagery and animation. Such is the case as well with the children's book character Noddy, who has appeared in various iterations and with different means of animation ranging from stop-motion to CGI to this day. The BBC's investment in resources and personnel oriented to children's media during this time would also provide avenues for the service's eventual inclusion of animation—particularly stop-motion animation, which could be derived from some of the same resources and skill-sets as live action puppetry. Puppeteer Gordon Murray for example, would branch off from his work on the "Watch with Mother" segment "The Woodentops" and other live action puppet shows to create several stop motion animated children's series in the 1960s, including "Camberwick Green" (1966), "Trumpton" (1967) and "Chigley" (1969). Modelmaker Peter Firmin and writer Oliver Postgate similarly created several stop-motion animated works for children during this period, including "Pingwings" (1961–1964), "Pogles' Wood" (1966–1967) and "Clangers" (1969–1972). It is during this period that ties between the UK's children's animation and several other British media and literary tendencies consolidated, with shows of this period providing a blueprint for future children's TV focussing on rural communities and day-to-day interpersonal relationships. Within this tendency, strong ties can be seen within children's TV and much older pastoral children's literature, social realist cinema and documentary, and the theatrical comedy of manners. This transition from puppetry to stop-motion also demonstrates the influence of Eastern European animation (such as that of Czech animator Jiří Trnka and his followers), with its own proclivity for wood and felt animation puppets and often static facial features. Trnka's work helped to inspire British production companies, including Pete Bryden and Ed Cookson's BBC-commissioned stop-frame animated children's series Summerton Mill (2005).
