The Radio In 1933, E.B White denoted the radio and its influence on his rural community as "godlike presence"(Lewis 26). Radio, first modern mass medium of communication has influenced twentieth century as much as did the automobile. It transformed America into a land of entertainment, education, information exchange, and a common culture.
It came with immense power because only a single speaker had the ability to sow the seeds of entertainment, information, propaganda, political and religious fervor, culture, and even negativity everywhere (Lewis 26).This paper briefly studies the formation, evolution, and impact of radio on human life and concludes that radio is not doomed by its fleshier competitors, but it has evolved. Radio refers to the signaling or audio communication by using electromagnetic radiations. In its early days, it was developed as a "wireless telegraph", for one point to the other point links. The wireless telegraph made it possible to send messages to multiple locations at the same time, by using dots-and-dashes of telegraphic code in early days, while in full audio during later periods (White). The historical Background James Clerk Maxwell, a Scottish physicist was influenced by Michael Faraday's ideas and work on electromagnetism. Faraday's work described that electric and magnetic effects arise from the lines of force around conductors and magnets. Maxwell developed an analogy about the way lines of force behave and the liquid flow; he derived equations that represented the electric and magnetic field. Based on Faraday's ideas, Maxwell produced a paper in 1855. ...
