In 2000, economist Francis X. Diebold published the first version of a paper titled “Big Data Dynamic Factor Models for Macroeconomic Measurement and Forecasting.” After being interviewed on his use of the term “big data” by NYTimes.com blogger Steve Lohr, Diebold undertook his own investigation, in which he concluded: “The term ‘Big Data,’ which spans computer science and statistics/econometrics, probably originated in the lunch-table conversations at Silicon Graphics Inc. (SGI) in the mid 1990s, in which John Mashey figured prominently.”
