This chapter compares the political cultures in the four countries analysed in this volume. Based on an inductive qualitative approach that singles out specificities in how political communication advisors and journalists interact within historical/institutional and professionalist/normative conditions and related constraints, the findings challenge earlier research on political communication culture. The chapter shows how political communication culture may act as a modifying factor in times of systemic change. It also reveals differences between and within countries that are often seen as forming distinct groups: Finland and Sweden as Nordic countries and Lithuania and Poland as Central European countries that have undergone recent fundamental system changes. The chapter ends with a discussion of how changes in the technological communication environment may affect political communication culture simultaneously in all four countries.
