In Germany, ACNielsen gained particular reputation for their introduction of the Nielsen areas (or Nielsengebiete in German), each of which includes one or more German federal states sharing a similar economic structure, culture, and consumer behaviour. To a considerable part, marketing strategies in heterogeneous Germany depend on the Nielsengebiete, this even leading to the result that some trademarks or marketing campaigns have only been introduced in some of the Nielsengebiete. In addition, in many newspapers or magazines disseminated nationwide, ads may be placed for just only one or some Nielsengebiete; the circulation figures of print media are often stated according to Nielsengebiete, as well.
