As part of the research study "To host or not to host the Olympics - A transnational perspective" more than 12,000 citizens in eleven European countries and the USA were interviewed about the organization of the Olympics in their home country. The aim of the study was to critically question the opportunities and risks involved in hosting a sports mega event. The study was carried out by the CAMP BECKENBAUER Competence Team of WHU - Otto Beisheim School of Management. Country profiles as well as the analysis of supporters, undecided, and opponents of an Olympic orientation disclose relevant information for decision-makers in sports, business, and society. With the help of independent, transnational perspectives, the study develops concrete approaches for the mobilization of population.
