Wolfgang Glatthaar International Business Machines (IBM), Gennany The rapid developments in infonnation technology (IT) will continue through the coming years. New application areas will be added.

VI Preface Up to now the use of infonnation technology in the private household has not been regarded as highly significant by either business or science, even though PCs have become widespread in the private sphere. In the ESPRIT framework there have been individual projects dealing with home networks, and in a number of Asian and European countries, as well as America, experiments with interactive television are taking place. Internet and commercial online services are experiencing rapid growth. This application area for infonnation technology in the private household, which is generating increasing business attention, must also be the subject of appropriate research activities.
