There was a "cough-and-you-miss-it" mention of Factiva on NPR's Morning Edition Tuesday when Wall Street Journal economics editor David Wessel said he found 2,000 mentions of "stagflation" in the Factiva database. (Thanks to attentive listener John C. in New Jersey. )
We know that journalists use Dow Jones Factiva's archive of mainstream media to do this kind of light text mining all the time.
I took David's statement a bit further and looked for the word in the past 14 months using Dow Jones Insight. I'm not sure what time frame he used. I found 4,603 documents mentioning that term during that time and certainly a lot more interest of late. This was from about 6,000 world-wide mainstream media publications and wires.
(Full disclosure: The Journal and Factiva are both owned by Dow Jones, which also pays my salary.)
