A note about the importance of mouth-to-mouth advertising, with blogs being one of its incarnations on the Internet:
NOTRE DAME USA — Ob ein Kinofilm zum Kassenschlager wird, hängt davon ab, was die Besucher der ersten Vorstellungen darüber erzählen. Das zeigte ein US-Physiker anhand eines mathematischen Modells, mit dem er den Erfolg von 44 Kinostreifen untersuchte. Demnach kann die Mundpropaganda die Besucherzahlen langfristig stärker beeinflussen als das Marketing oder die Grösse des Publikums, das ursprünglich mit dem Film angesprochen werden sollte.
