New technologies and new media have significantly influenced the process of political communication. They have created new opportunities such as the great interactivity of communication, the personalization of a message or an uncountable number of possibilities for campaigning. This publication is a collection of socio-political studies which analyze the phenomenon of political communication in the 21st century. The main focus is on new media, especially on the Internet as well as on social media or social networks. However, there are also papers which examine traditional channels of political communication in the era of new technologies. Moreover, to the advantage of this book, the chapters explore the phenomenon of political communication not only in the USA and Western Europe, but also in Central Europe, Latin America and Africa.
