"Media culture" is a relatively young concept in cultural studies. This volume contributes to its delineation and connects it with social action, which is grounded in sociology. To theoretically grasp the complex relationship between culture and social action in the present, one of the starting points proposed is to understand media cultures as the realization of mediated cultural practices within their respective social constellations at specific historical moments. The contributions in this volume reflect on the societal significance of media and media interpretation offers in use; they illuminate selected aspects of social action within a media culture, where media and everyday experiences are intertwined in ways that, for example, relate to couple and gender relationships, youth, and friendship.
