Years before the advent of music streaming, Sirius and XM established satellite radio services that attracted paying subscribers through their ever-expanding lineup of niche music channels and exclusive celebrity-hosted programming. Music in Orbit is the first book to explore how satellite radio bridges legacy broadcast music radio and streaming platforms, serving as both precursor and integral player in today's streaming media environment. Arguing for the ongoing significance of radio in the digital age and the pernicious effects of monopoly power on the vibrancy of contemporary music industries,  Music in Orbit offers essential context for the serious problems now facing working musicians, music consumers, and music communities.
