HISTORY
Radio began in the 19th century. In 1894 the young Italian inventor Guglielmo Marconi began working on the idea of building a commercial wireless telegraphy system based on the use of Hertzian waves (radio waves), a line of inquiry that he noted other inventors did not seem to be pursuing. In 1895 he built a radio wave system capable of transmitting signals at long distances (1.5 mi./ 2.4 km). Marconi found from his experiments the phenomenon that transmission range is proportional to the square of antenna height, known as "Marconi's law."
Early uses were maritime, for sending telegraphic messages using Morse code between ships and land. The earliest users included the Japanese Navy scouting the Russian fleet during the Battle of Tsushima in 1905. One of the most memorable uses of marine telegraphy was during the sinking of the RMS Titanic in 1912, including communications between operators on the sinking ship and nearby vessels, and communications to shore stations listing the survivors.
Marconi's experimental apparatus proved to be the first engineering complete, commercially successful radio transmission system. In June 1912 after the RMS Titanic disaster, due to increased production Marconi opened the world's first purpose-built radio factory at New Street Works, also in Chelmsford, England.
Radio was used to pass on orders and communications between armies and navies on both sides in World War I; Germany used radio communications for diplomatic messages once it discovered that its submarine cables had been tapped by the British. The United States passed on President Woodrow Wilson's Fourteen Points to Germany via radio during the war.
Broadcasting began from San Jose, California in 1909, and became feasible in the 1920s, with the widespread introduction of radio receivers, particularly in Europe and the United States. Besides broadcasting, point-to-point broadcasting, including telephone messages and relays of radio programs, became widespread in the 1920s and 1930s. Another use of radio in the pre-war years was the development of detection and locating of aircraft and ships by the use of radar (RAdio Detection And Ranging).

This was, for all intents and purposes, the first transmission of what is now known as amplitude modulation or AM radio. The first radio news program was broadcast August 31, 1920 by station 8MK in Detroit, Michigan, which survives today as all-news format station WWJ under ownership of the CBS network. The first college radio station began broadcasting on October 14, 1920 from Union College, Schenectady, New York under the personal call letters of Wendell King, an African-American student at the school.
That month 2ADD (renamed WRUC in 1947), aired what is believed to be the first public entertainment broadcast in the United States, a series of Thursday night concerts initially heard within a 100-mile radius and later for a 1,000-mile (radius. In November 1920, it aired the first broadcast of a sporting event. At 9 pm on August 27, 1920, Sociedad Radio Argentina aired a live performance of Richard Wagner's opera Parsifalfrom the Coliseo Theater in downtown Buenos Aires. Only about twenty homes in the city had receivers to tune in this radio program. Meanwhile, regular entertainment broadcasts commenced in 1922 from the Marconi Research Centre at Writtle, England.
Sports broadcasting began at this time as well, including the college football on radio broadcast of a 1921 West Virginia vs. Pittsburgh football game
Today, radio takes many forms, including wireless networks and mobile communications of all types, as well as radio broadcasting. Before the advent of television, commercial radio broadcasts included not only news and music, but dramas, comedies, variety shows, and many other forms of entertainment (the era from the late 1920s to the mid-1950s is commonly called radio's "Golden Age"). Radio was unique among methods of dramatic presentation in that it used only sound.

IMPACTS ON SOCIETY AND PEOPLE
People thought that family and society would be ruined by phones, radio and TV. By 1930, 40% of households had radios.
Radios brought the family together in a way that no other news medium could. For the first time the family could listen to the news at the same time.
The radio also brought things that were previously out of the families reach into their homes. Never before had the voice of the president been heard until FDR began his "Fireside Chats". They were a series of thirty evening radio addresses given by United States President Franklin D. Roosevelt between 1933 and 1944. These brought the president into the private homes of the American citizens.

The War of the Worlds is an episode of the American radio drama anthology series The Mercury Theatre on the Air. It was performed as a Halloween episode of the series on October 30, 1938, and aired over the Columbia Broadcasting System radio network. Directed and narrated by actor and future filmmaker Orson Welles, the episode was an adaptation of H. G. Wells's novel The War of the Worlds (1898).
The first two thirds of the 62-minute broadcast were presented as a series of simulated news bulletins, which suggested to many listeners that an actual alien invasion by Martians was currently in progress. Compounding the issue was the fact that the Mercury Theatre on the Air was a sustaining show (it ran without commercial breaks), adding to the program's realism. Although there were sensationalist accounts in the press about a supposed panic in response to the broadcast, the precise extent of listener response has been debated, particularly since the show was not drawing a large share of the radio audience. Many more Americans were listening to Edgar Bergen; however, when Bergen's opening comedy routine ended and gave way to a musical interlude, many people may have started turning the radio dial to see what else was on. Those people found a radio show that sounded like a real account of an alien attack. The show did issue a disclaimer at the beginning of the show, but the people tuning in late did not hear that announcement and so a small panic did occur.
In the beginning of radio it was used for information to the masses it has sense moved to a medium of entertainment.
