Riepl's law is a hypothesis formulated by Wolfgang Riepl in 1913. It is frequently cited in discussions about newly emerging forms of media in the scientific community in German-speaking countries.
Riepl, the chief editor of Nuremberg's biggest newspaper at the time, stated in his dissertation about ancient modes of news communications (original title: "Das Nachrichtenwesen des Altertums mit besonderer Rücksicht auf die Römer") that new, further developed types of media never replace the existing modes of media and their usage patterns. Instead, a convergence takes place in their field, leading to a different way and field of use for these older forms.
This hypothesis is still considered to be relevant, explaining the fact that new media never make the "old" media disappear.
"I believe in Riepl's law...Books have not replaced storytelling. Newspapers have not replaced books; radio has not replaced newspapers; and television has not replaced radio. It follows that the Internet will not replace television or newspapers"
