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.)
Psychology
Psychology is the science of behavior and mind, including conscious and unconscious phenomena, as well as feeling and thought. It is an academic discipline of immense scope and diverse interests that, when taken together, seek an understanding of the emergent properties of brains, and all the variety of epiphenomena they manifest. As a social science it aims to understand individuals and groups by establishing general principles and researching specific cases.
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.
Television
There is nothing wrong with your television set. Do not attempt to adjust the picture. We are controlling transmission. If we wish to make it louder, we will bring up the volume. If we wish to make it softer, we will tune it to a whisper. We will control the horizontal. We will control the vertical. We can roll the image, make it flutter. We can change the focus to a soft blur or sharpen it to crystal clarity. For the next hour, sit quietly and we will control all that you see and hear. We repeat: there is nothing wrong with your television set. You are about to participate in a great adventure. You are about to experience the awe and mystery which reaches from the inner mind to The Outer Limits.
The Outer Limits (1963 TV series) (Opening narration) created by Leslie Stevens
Television
News is not at all an easy thing to do on television. A good many of the main news items are not easily made visual — therefore we have the problem of giving news with the same standards that the corporation has built up in sound.
Sir Ian Jacob, BBC director General , c. July 1954
Radio
It is impossible to understand the American public without taking into account the tremendous psychological effect of bringing up a generation of people in a daily environment of advertising. It is impossible to escape the advertising man; his sales talk assaults us in the morning newspaper, in the street car, with billboards along the highways, and in his shameless use of the radio. This means that from morning till night, in the midst of our work as in our recreation, we live constantly in an atmosphere of intellectual shoddiness. Every popular prejudice and vulgar conceit is played upon and pandered to in the interests of salesmanship. Everywhere material interests and herd opinion are strengthened to the loss of personal independence. The tendency is to think and speak for effect rather than out of one's inner life. There is a marked decline the ability to play with ideas, or to live the spiritual life for its own sake. Hence a decline in civilization of interest, humor and urbanity. Advertising tends to make mechanized barbarians of us all.
Everett Dean Martin, The Conflict of the Individual and the Mass in the Modern World (1932), pp. 29-30
