Digital culture is a new complex notion: today digital trends are increasingly interloping with the world of culture and arts, involving different aspects of convergence of cultures, media and information technologies, and influencing new forms of communication. The new possibilities created by ICT – global connectivity and the rise of networks – challenge our traditional ways of understanding culture, extending it to digital culture as well. So, culture today should be understood as an open and dynamic process that is based on interactive communication, and we cannot think of it as an enclosed system which makes up a “cultural mosaic” with other similar or diverse cultural systems. The ICT and especially the Internet, has given these interrelations a new dimension, by changing our relation towards knowledge and knowledge society, by intensifying the flow of cultural goods and services, and by causing a new understanding of cultural creativity. The papers in the book entitled Digital Culture: The Changing Dynamics examine possible shifts in the integration of new technologies and digital culture in the processes of affirming cultural diversity and intercultural communication by presenting different case studies and trend analyses – examining the changes brought about by the new context of the interactive and participatory Internet and the responses of the cultural sector to them, and analysing how cultural policies deal with digital culture. By providing insights into these interrelated aspects, the book is trying to answer the question – can we talk about cultural diversity in the digital domain and what are the current trends? To understand the interrelation of the local and the global, the articles in this book analyse existing practices in the digital realm. The SEE context is analysed in one part of this book, thus providing evidence-based research of digital diversity trends and informing cultural policies in the SEE region. The Introduction aims to give an understanding of digital culture, viewing it from the perspective of a common resource for knowledge society and as a new social ecology that conditions experiences and opportunities of citizens today, where the digital network environment has brought on new practices, possibilities and threats. Part One, entitled Digital Culture – The New Social Ecology, discusses various aspects of digital culture, from its move to the real world – ambient intelligence, to its aspects related to (free) communication – analyzing the social and cultural changes which emerged with the appearance of media technologies, as well as examining how these changes influence the transformations of the mediated public sphere and considering the social implications of the transformation of the cultural and media production and the way this reflects on issues of copyright regulation. The contributions in Part One try to sketch the development directions digital culture is taking and their impact on the social ecology that we are shaping through building new legislative and institutional structures. Part Two, Conceptualising Policies for Digital Culture, brings contributions that analyze how cultural policies deal with digital culture and new virtual structures such as cultural portals, and look at issues arising from the new relations between real and virtual spheres. In the Part Three, Cultural Practices in the Digital Territory, authors discuss the development of digital structures in the cultural sector, and try to analyze and propose a cultural portals ecology and shed light on the nature of the changes the cultural sector has to take into account when developing its services in the virtual context.
