+                                        Werbung dient dazu, auf bestimmte Produkte, Angebote oder den Markt im

+                                        werden, etwa das Internet, Zeitungsannoncen oder auch per TV/Radio.
+                                        Im Gegensatz zu Rabatten (die zeitabhängig am besten funktionieren) ist Werbung
+                                        stark von der Zielgruppe abhängig. Insbesondere in der Kombination mit anderen
+                                        Marketingmaßnahmen kann sie so ihre volle Wirkung entfalten.
