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.

New perspective on information technology This development has already generated considerable market dynamics.

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.
