It appears to be this company: [link to www.gfk.com
I would look particularly at their history:
"Vershofen’s treatise of 8 August 1934 on "Broad-based consumer surveying" represents the birth certificate of GfK, which was registered as a society
headquartered in Berlin.
The aim of the society, which was named "Gesellschaft für Konsumforschung” shortly after its establishment, was described in its articles of association as: "A company whose purpose is to examine the habits and attitudes of consumers to consumer goods within the territory of the German Reich
by appropriate measures on a continuous basis using special surveys and to process the findings of such studies according to scientific principles for the purposes of economic practice and teaching.” This was the birth of institutional market research in Germany." -- [link to www.gfk.com
It gets creepier. Their motto is "Own the Future."
I don't have time to do this, but I suggest that if interested, you look for connections to Nazi operations, and Operation Paperclip.
Enjoy, you should have conspiracy fodder for at least a week.
