TNS Magasin is part of TNS. Our research methodologies can be combined with and supported by other TNS services such as Worldpanel, which continuously tracks purchasing behaviour around the world using shopper panels.
This is particularly useful for showing how products are consumed as well as understanding shopper missions, shopper repertoires and shopper responses to promotions.
