Through the Internet the boundaries between the various media forms, between institutionalized and informal communication have become blurred. However, this also applies to the boundaries between customized communication for the individual and mass communications. At the same time – with regard to printed products as well – amateur sources have now emerged alongside articles by professional journalists: articles by “reader reporters”, omnipresent images from digital cameras and cell phones and opinions of interested users. As such contemporary journalism is in many respects convergent and interactive. Though customary professional press and radio products still play a central role in the new-look media content as well, to many young people the social network, the “community” appears to be more credible and more attractive. The most successful offerings include the German- language Facebook, MySpace, StudiVZ and SchülerVZ. To­gether with blogs and micro-blogging platforms such as Twitter these have emerged as a digital public presence that is growing rapidly and increasingly impacting on public opinion forming.
