Around the world small children under six are regularly captivated by programmes produced especially for them by adults who inhabit a distinctive production community. Alongside enduring stalwarts such as Sesame Street, recent arrivals such as Blues Clues, Teletubbies and Bob the Builder have become enduring favourites. The international presence of these series on preschool channels and blocks underlines the phenomenal changes experienced by preschool television in recent years. Focusing on experience in Britain and the US, this book explains how the preschool television sector has shifted from an essentially small localised and economically restricted industry to become a much more complex, commercially-driven global business. Drawing on industry interviews combined with observations, it considers the range of forces that shape the development and creation of contemporary preschool television and examines how those involved in its creation and distribution negotiate the wider commercial, creative and curricular influences that impact production.
