In 2000 the RAND Corporation invited a group of historians—including me—to address a newly pressing question: Would digital media revolutionize society as profoundly as Gutenberg and movable type? Two decades later, John Thompson’s answer is yes, but not entirely as predicted. And our forecasts were often wrong because we overlooked key variables: We cannot understand the impact of technologies “without taking account of the complex social processes in which these technologies were embedded and of which they were part.”
Mr. Thompson provides that context in “Book Wars” (Polity, 511 pages, $35), an expert diagnosis of publishers and publishing, robustly illustrated with charts, graphs, tables, statistics and case studies. An emeritus professor at Cambridge University, Mr. Thompson published an earlier dissection of that industry, “Merchants of Culture,” in 2010, but now he finds that capitalist landscape radically transformed.
