Two concepts that have been used to describe the changes with regards to media and politics during the last fifty years are the concepts of mediationand mediatiza- tion. However, both these concepts are used more often than they are properly defined.Moreover,there is a lack of analysis of the processof mediatization,although the concept as such denotes a process.Thus the purpose of this article is to ana- lyze the concepts of mediated and mediatized politics from a process-oriented per- spective.The article argues that mediatization is a multidimensional and inherently process-oriented concept and that it is possible to make a distinction between four phases of mediatization. Each of these phases is analyzed.The conclusion is that as politics becomes increasingly mediatized, the important question no longer is related to the independence of the media from politics and society.The important question becomes the independence of politics and society from the media.
