Die Website TV Tropes hat sich zum Ziel gesetzt, den wiederkehrenden Elementen in Filmen und Fernsehen auf die Spur zu kommen (via clickomania.ch):
“TV Tropes is a wiki, sort of like Wikipedia but using different software and with a different purpose. We describe and collect examples of Tropes in Media. We also host reviews, liveblogs, and have forums where you can talk with other tropers.
A trope is a narrative device or convention used in storytelling or production of a creative work.”
