Evidence

Yet even now, times were changing; and in the next fifty years, for the first time since Gutenberg, cultural commentators began to doubt whether books could hold their own. … The twentieth century, it soon became clear, would be different. From the first days of radio and then cinema these were real competitors, not just for much-valued leisure time, but also for possession of the imaginative world once shaped primarily by print. — Andrew Pettegree, Arthur der Weduwen, The Library- A Fragile History, 798
