Providing a lucid and concise historical account of how the computerization of newsrooms from the mid-1960s to the 1990s changed the work routines of US newsworkers, Mari makes a convincing case in his book for focusing on pre-Internet technologies during this era by arguing that no other generation of journalists has experienced such a rapid shift from analog to electric and “electronic,” and then digital technologies within such a short span of time. Paying particular attention to four disruptive technologies over three decades—namely, mainframe computers, minicomputers, microprocessors, and personal computers—Mari traces and depicts the historical context of the relationship between newsworkers and their machines vividly, foregrounding the co-evolution of editorial technology, newsworkers and newswork. Drawing from literature in the fields of science and technology studies, journalism studies, and the sociology of work, this book’s arguments are based on Mari’s analysis of more than 1,000 trade publications, independent studies, and archival material from the US Living Computer Museum.
