The repeat grilling by the UK parliament’s DCMS committee today of Alexander Nix, the former CEO of the now ex company Cambridge Analytica — aka the controversial political and commercial ad agency at the center of a Facebook data misuse scandal — was not able to shed much new light on what may or may not have been going on inside the company.

But one nugget of information Nix let slip were the names of specific data aggregators he said Cambridge Analytica had bought “consumer and lifestyle” information on US voters from, to link to voter registration data it also paid to acquire — apparently using that combined database to build models to target American voters in the 2016 presidential election, rather than using data improperly obtained from Facebook.
