“The derivative information of the second-rate copyist is far from independent of what has gone before. Thus the conventional love story, the conventional detective story, the average acceptable success tale of the slicks, all are subject to the letter but not the spirit of the law of copyright. There is no form of copyright law that prevents a movie success from being followed by a stream of inferior pictures exploiting the second and third layers of the public’s interest in the same emotional situation… I repeat, the prevalence of cliches is no accident, but inherent in the nature of information.” – Norbert Wiener
