Abstract
The terms ‘interactivity’ and ‘interactive media’ became significant buzzwords during the late 1980s and early 1990s when the multi-media euphoria fascinated politicians, economists, and researchers alike. However, right from the beginning of the scientific debate, the inconsistent usage of the term ‘interactivity’ massively complicated the comparability of numerous empirical studies. This is where this article joins the discussion. First, the article sheds light on the terminological origins of ‘interactivity’ and distinguishes the term from cognate expressions. Further, it restructures and extends existing findings on the basis of a new analysis framework which considers three levels of interactive communication. Finally, it delivers a systematic overview of specific criteria of interactive communication.
