    Abstract
    Der entscheidende Aspekt in Shannons mathematischer Theorie der Kommunikation ist, "daß die tatsächliche Nachricht aus einem Vorrat von möglichen Nachrichten ausgewählt wurde". Ahnlich in der binären Logik des Fernsehquiz': Hier wählen die Ratenden aus einer endlichen Zahl beruflicher Lebenswelten, die gleichsam durch sogenannte "typische Handbewegungen" in diskrete Einheiten zerhackt werden. Mathematik und Unterhaltung kommen dabei in einem überein: in der Bedeutungslosigkeit. Shannons Modell abstrahiert davon, ob Nachrichten "Bedeutung" haben, also sich "auf bestimmte physikalische oder begriffliche Größen" beziehen. Ihn interessiert nur, ob und wie die Informationen im gegebenen Kanal störungsfrei übertragen werden können. Die Unterhaltungsindustrie wiederum, deren binäre Logik auf der Unterscheidung zwischen dem Interessanten und dem Langweiligen beruht, kümmert sich nicht darum, ob sich die generierte Information auf wirtschaftliche oder politische Größen bezieht. Sie interessiert nur, ob der Fernseher eingeschaltet bleibt. Entscheidend ist für Shannon der Aspekt der Auswahl etwa aus Buchstaben eines Alphabets, weil damit die Statistik zum Zug kommen kann. Damit läßt sich beispielsweise der Informationsgehalt der deutschen Schriftsprache messen. Nimmt man an, daß alle 30 Zeichen (29 Buchstaben plus Leerzeichen) gleich verteilt sind, ergibt sich ein Informationsgehalt von 4,9 bit. In Wirklichkeit ist jedoch die Wahrscheinlichkeit für die Wahl der verschiedenen Buchstaben, Silben und Wörter in einer natürlichen Sprache in jedem Stadium des Prozesses von der vorhergegangenen Auswahl abhängig. Einen solchen Prozeß bezeichnet die Wahrscheinlichkeitstheorie als Markow-Prozeß oder Markow-Kette. Berücksichtigt man also die Wahrscheinlichkeitsverteilung von Buchstabenfolgen, so erhält man einen viel kleineren mittleren Informationsgehalt der deutschen Schriftsprache, nämlich 1,6 bit.
