    Abstract
    Mit dem Aufkommen der Wissensgesellschaft wird Information zum Wirtschaftsgut. Digitale Wirtschaftsgüter - Content wie Software - werden entweder selbst vermarktet (z.B. bei kommerziellen Informationsdiensten) oder dienen als Lockangebote für Werbung (z.B. bei Suchmaschinen mit "sponsored links"). Aufgrund der Besonderheiten des vertriebenen Produkts unterscheiden sich die Wettbewerbsstrategien von Informationsanbietern von denen nicht-digitaler Güter. Zu beachten ist zudem der "illegale" Informationsmarkt (Schwarzkopien). Im Zentrum des Buches steht zwar eine ökonomische Analyse des Informationsmarktes, behandelt werden aber auch Informationssoziologie und -politologie, Informationsrecht sowie Informationsethik.
