This Day in Network Radio [PDF ebook] 
A Daily Calendar of Births, Deaths, Debuts, Cancellations and Other Events in Broadcasting History

For each day of the calendar, this unique work details events that have significantly affected American network radio since the mid-1920s. Entries recount occasions, practices, or decisions which left indelible marks on broadcasting (listed by date of occurrence); the debuts and cancellations of programs; and births and deaths of important people in radio history–not only headliners but also less recognized individuals, from radio executives and producers to writers, sound techs, engineers, consultants, hawkers and impersonators.
