Internetkommunikationsdienste sind Dienste, die zwischenmenschliche Kontakte über das Internet ermöglichen. Zu diesen zählen etwa die Internettelefonie (Voice over IP, z.B. Skype), Instant Messaging (z.B. WhatsApp) und die E-Mail. Viele dieser Dienste sind bereits seit den 1990er Jahren populär, doch ihre rechtliche Einordnung und die daran anknüpfenden Regulierungsfolgen sind nach wie vor umstritten. In dem Werk wird untersucht, ob sie de lege lata vom Telekommunikationsrecht erfasst sind. Sodann wird erforscht, welche Regelungen dieses Rechtsgebiets sinnvoll auf derartige Angebote anwendbar sind oder künftig sein sollten. Analysiert werden Normen des sektorspezifischen Kartellrechts, des Kundenschutzes, der öffentlichen Sicherheit sowie des Datenschutzrechts. Abschließend wird angesichts des schnellen technischen Wandels in der Telekommunikationsbranche die Reaktionsfähigkeit des hierzulande geltenden Telekommunikationsrechts im Vergleich zum US-amerikanischen Recht untersucht.
