¬Der Markt für elektronische Konsumentendienste und seine Bedeutung im Gesamtmarkt für elektronische Informationsdienste in Deutschland

Abstract
Im Gegensatz zu den Entwicklungen elektronischer Informationsdienste im Geschäftsbereich verzögerte sich der Take-off der elektronischen Konsumentendienste, aber seit 1995 befinden sich auch die Consumer Services im Boom. Soweit es um die zentrale wirtschaftliche Größe 'Umsatz' geht, wurden diese Entwicklungen bislang nicht von der Marktforschung erfaßt. Erstmalig wurden in den jährlichen Umsatzerhebungen des Institute for Information Economics auch die Anbieter elektronischer Konsumentendienste sowie die Internetanbieter im Internet einbezogen. Damit wird erstmalig eine fundierte Schätzung der Größe des Gesamtmarktes für elektronische Informationsdienste für geschäftliche und private Zwecke möglich. Die Interpretation der gewonnenen Ergebnisse führt zu Einsichten, die nach dem Stand der öffentlichen Diskussion zum Teil überraschen
