This book, first published in 1990, offers an in-depth analysis of the `fundamental beliefs' of radio. This refers to the common understanding of what the radio enterprise is - and should be - about: entertainment and information. A major thrust of this book is to arrive at a set of fundamental beliefs about the values and the realities of the radio business in regard to entertainment programming - a set of beliefs that may or may not be right, or forever, but that might at least provide a basis for developing programming strategies. Most other books on radio programming describe the formats and programming that already exist. This one starts with a clean sheet of paper and the question `What do listeners really want from radio?'
