Chapter 6 traces the rise of merchandising agencies as a distinct and independent profession in the United Kingdom. It focuses on the most influential independent agency of the period, Walter Tuckwell & Associates. A former Disney employee, Tuckwell fostered a network connecting and linking commercial and legal opportunities offered by television programmes and the emerging demand for child-related products. The chapter discusses the specific relationship between content creation and marketing that arose during the earliest days of television. This entails a discussion of Tuckwell’s role at the British Broadcasting Corporation (BBC), where objections to the development of merchandising inside the corporation were managed. Commercial television changed agendas, leading to stabilisation in contractual practices between broadcasters, licensing agencies and sectors such as the toy, publishing and food industries; all eager to capitalise on the new communication medium. By the late 1960s, children’s participation in commodification was a fully integrated component of intellectual property practice and an integral part of television culture, regardless of the character of the broadcast licence.
