While so many books on technology look at new advances and digital technologies, The Routledge Companion to Media Technology and Obsolescence looks back at analog technologies that are disappearing, considering their demise and what it says about media history, pop culture, and the nature of nostalgia. From card catalogs and typewriters to stock tickers and cathode ray tubes, contributors examine the legacy of analog technologies, including those, like vinyl records, that may be experiencing a resurgency. Each essay includes a brief history of the technology leading up to its peak, an analysis of the reasons for its decline, and a discussion of its influence on newer technologies.
