GfK
(Redirected from Gesellschaft für Konsumforschung)
The GfK (Gesellschaft für Konsumforschung) is Germany's largest market research institute and the fifth largest such institute worldwide. It was founded in 1934 by an association of university teachers, among them Ludwig Erhard, later minister of economics and chancellor of Germany. The institute is probably best known for its measurment of German TV audience ratings which it carries out since 1991, but it has since expanded into several other European countries and into all fields of marketing research.
