Around this time, telephones also transmitted opera performances from Paris to London.

In 1909, this innovation emerged in the United States as a pay-per-play phonograph service in Wilmington, Delaware.

The technology needed to build a radio transmitter and receiver was relatively simple, and the knowledge to build such devices soon reached the public.

Amateur radio operators quickly crowded the airwaves, broadcasting messages to anyone within range and, by 1912, incurred government regulatory measures that required licenses and limited broadcast ranges for radio operation.

By the 1870s, telegraph technology had been used to develop the telephone, which could transmit an individual’s voice over the same cables used by its predecessor.

When Marconi popularized wireless technology, contemporaries initially viewed it as a way to allow the telegraph to function in places that could not be connected by cables.Early radios acted as devices for naval ships to communicate with other ships and with land stations; the focus was on person-to-person communication.However, the potential for broadcasting—sending messages to a large group of potential listeners—wasn’t realized until later in the development of the medium. This includes radio used for person-to-person communication as well as radio used for mass communication. Although most people associate the term Guglielmo Marconi is often credited as the inventor of radio.As a young man living in Italy, Marconi read a biography of Hienrich Hertz, who had written and experimented with early forms of wireless transmission.At first, ads ran only during the day, but as economic pressure mounted during the Great Depression in the 1930s, local stations began looking for new sources of revenue, and advertising became a normal part of the radio soundscape..In 1926, RCA started the National Broadcasting Network (NBC).This regulation also gave the president the power to shut down all stations, a power notably exercised in 1917 upon the United States’ entry into World War I to keep amateur radio operators from interfering with military use of radio waves for the duration of the war.Wireless technology made radio as it is known today possible, but its modern, practical function as a mass communication medium had been the domain of other technologies for some time.After the World War I radio ban lifted with the close of the conflict in 1919, a number of small stations began operating using technologies that had developed during the war.Many of these stations developed regular programming that included religious sermons, sports, and news.
