Film
A film, also called a movie, motion picture, theatrical film, or photoplay, is a series of still images that, when shown on a screen, create the illusion of moving images. (See the glossary of motion picture terms.)
History
History (from Greek ἱστορία, historia, meaning "inquiry, knowledge acquired by investigation") is the study of the past as it is described in written documents. Events occurring before written record are considered prehistory. It is an umbrella term that relates to past events as well as the memory, discovery, collection, organization, presentation, and interpretation of information about these events. Scholars who write about history are called historians.
Radio
Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.
Television
Television (TV) is a telecommunication medium used for transmitting moving images in monochrome (black and white), or in colour, and in two or three dimensions and sound. The term can refer to a television set, a television program ("TV show"), or the medium of television transmission. Television is a mass medium for advertising, entertainment and news.
History
The great historian John Hope Franklin, who helped to get this museum started, once said, “Good history is a good foundation for a better present and future.” He understood the best history doesn’t just sit behind a glass case; it helps us to understand what’s outside the case. The best history helps us recognize the mistakes that we’ve made and the dark corners of the human spirit that we need to guard against. And, yes, a clear-eyed view of history can make us uncomfortable, and shake us out of familiar narratives. But it is precisely because of that discomfort that we learn and grow and harness our collective power to make this nation more perfect.

Film
… a pastime for helots, a diversion for uneducated, wretched, worn-out creatures who are consumed by their worries, … a spectacle which requires no concentration and presupposes no intelligence,… which kindles no light in the heart and awakens no hope other than the ridiculous one of someday becoming a ‘star’ in Los Angeles.
Georges Duhamel, describing cinema, Scènes de la vie future (1930), p. 58.
Radio
Books are the friends of solitude. They develop individuality and freedom. In solitary reading a man who is seeking himself has some chance of finding himself. … Radio, on the other hand, is now the chief agent of imperialism. It does not purify the spirit of man, does not, like the book, bring him back to the sanctuary of solitude, but throws him to the lions, subtly preparing his mind for the blood and chains of public sacrifice.
Georges Duhamel, In Defense of Letters (1937), E. Bozman, trans. (1939), p. 42
