The aim of the paper is to describe and tentatively explain structural and behavioural shifts among tourism stakeholders provoked by new information and communication technologies. The paper is structured as follows: Section two delineates actual levels of ICT adoption in tourism. After having defined tourism business as being highly ‘information intensive’ section three summarizes ICT provoked patterns of change. For this aim, prominent models ‘explaining’ both demand side ICT acceptance and usage behaviour as well as supply side levels of ICT adoption are briefly discussed. Section four portrays selected innovative ICT applications in tourism. At the supply side they comprise new concepts of electronic business networks pushing forward (e.g. horizontal and vertical) online cooperation as well as auction-based online distribution at eBay. Lessons at the demand side comprise context aware (e.g. location based) information services, augmented reality applications and ‘Web-2.0’-based applications supporting both, production and sharing of user-generated content.
