Radio is the original mass electronic medium and it continues to be critical for audiences wanting news, information, music and entertainment. For over a century enthusiasts, scholars, practitioners, governments, businesses and listeners have developed and influenced radio, making it a fascinating medium to explore today. There is still no mass medium as ubiquitous as radio and the Internet has extended its geographical and temporal reach even further. Radio remains a key media form and technology, not only surviving the challenges of the screen and digital ages, but developing despite and because of them.This book is a collection of contemporary research by radio scholars from the United Kingdom, Canada, Australia and New Zealand. It explores different aspects of this both simple and complex medium, from early radio histories to the contemporary developments of radio on the Internet. Chapters engage with critical debates about the role of government, business and communities in how radio is used in our societies. Some chapters provide important new insights into making radio, and radio as a cultural force. Other chapters explore developments in research methodologies that enable deeper insights into contemporary radio and its audiences. This book provides a range of platforms for engaging with radio and radio research as a rich, vibrant and fruitful way to further our understandings of the media and ultimately, ourselves.
