A history of American and British television drama, this book charts how the two production systems have moved closer together since the 1970s: both observe each other to drive innovation, and both continuously turn to each other to find new markets and new production partners. Although earlier collaborations exist, this increased transnationalisation of US and UK television drama has intensified since the 1970s as the increased number of channels and new technologies such as the internet and cable and satellite have led to stronger competition. Examining genres as diverse as period drama, the mini-series, the super-soaps of Dallas and Dynasty, crime drama and the recent spout of celebrated British and American quality drama, this book investigates how marketing campaigns within the press continually return these dramas into the realm of the nations they represent.
