Zusammenfassung:
The paper shows why the three major European videotex programs (Prestel in the UK, Télétel in France and Bildschirmtext in the FRG), although similar in their initial objectives, have led to markedly contrasting results. Each country, based on its particular macro context (technological environment, government-industry relations, political structures, etc.), pursued a different `implantation strategy', made up of specific clusters of technical and organizational choices. These decisions structured the subsequent development and produced different dynamics: critical mass problems, specific technical frictions and particular political issues. Three strategic choices have been made of particular importance: (1) the technical design and mode of terminal diffusion; (2) the systems architecture; and (3) the mode of service supply.
