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.
Research
Research comprises "creative and systematic work undertaken to increase the stock of knowledge, including knowledge of humans, culture and society, and the use of this stock of knowledge to devise new applications." It is used to establish or confirm facts, reaffirm the results of previous work, solve new or existing problems, support theorems, or develop new theories. A research project may also be an expansion on past work in the field. Research projects can be used to develop further knowledge on a topic, or in the example of a school research project, they can be used to further a student's research prowess to prepare them for future jobs or reports. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, or the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, economic, social, business, marketing, practitioner research, life, technological, etc.

First radio, then television, have assaulted and overturned the privacy of the home, the real American privacy, which permitted the development of a higher and more independent life within democratic society.
Allan Bloom, The Closing of the American Mind (New York: 1988), p. 58
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
