Since the rise of film and television, radio has continued to evolve, with satellite radio and podcasts as its latest incarnations. Any understanding of the development of radio, like its visual counterparts, depends on closely examining the artistic ventures that preceded commercial acceptance. In Pieces of Sound, Daniel Gilfillan offers a cultural history that explores these major aspects of the medium by focusing on German radio broadcasting, providing a context that sees beyond programming to consider regulations, cultural politics, and social standardization. Gilfillan showcases the work of radio pioneers and artists over the past century, including Brecht’s work with the form, and how radio was employed before and after World War II. He traces how German radio broadcasters experimented with networked media not only to expand the artistic and communicative possibilities of radio, but also to inform perceptions about the advantages and direction of newer telecommunications media like Internet broadcasting and pirate radio, which artists are using today to engage with a medium that is increasingly coming under corporate control. Gilfillan astutely observes how claims made for the Internet today echo those made for radio in its infancy and puts forth a broad and incisive historical analysis of German cultural broadcasting.
