These days, I often feel like I’m using Big Data to figure out the history of Big Data so I can better understand how Big Data is making me obsessed with Big Data. There are a few things I know for sure about this often perplexing pattern:1. The history of Big Data and the rise of the Internet appeals to me in part because I know it is inextricably tied to the history of American National Security and the rise of the military-industrial complex, 1950-1990, which also feels super consequential. 2. The plethora of data-driven archival databases and the precise search methods within them make it possible—in ways unimaginable even fifteen years ago—to pin down the corporations, figures, and products that made possible both the incomprehensible vastness of our government’s worldwide surveillance state and the incomprehensible vastness of the Internet.
