Inventors: Gulieimo Marconi; Reginald Fessenden; Lee de Forest
Invented: Developed between 1899-1909.
The radio was not invented at one time, but was developed over time by several experimenters. The radio started as a wireless telegraph in 1899 when Irish-Italian Inventor, Guglieimo Marconi, wanted to send "Morse code messages without wires"(History.com). The purpose of the invention was to provide fast mobile communication service for corporate clients. The wireless telegraph was experimented with by other men in hopes of transmitting music. In 1906, Reginald Fessenden made a sophisticated radio transmitter, the high-frequency alternator, according to History.com. Not long after, between 1907 and 1909, Lee de Forest created the radio tube.
It wasn't until after World War I that the radio became popular. The number of radio stations increased from "30 in 1922 to 556 in 1923" according to History.com. Do to the popularity of the radio, advertisers want to take part of this new media. "What made radio so attractive to advertisers was the formation of networks: NBC (National Broadcasting Company, 1926), CBS (Columbia Broadcasting System, 1927), and MBS (Mutual Broadcasting System, 1934) offered advertisers instant access to a national audience" (history.com). The 1920's became known as the Golden Age of the Radio.
Before the invention, people would receive their news through newspapers and word of mouth. They also read the paper for entertainment. When the radio started coming into homes, the culture changed. For the first time people could hear music (without having to play an instrument), listen to talk shows and speeches. By 1933, 2/3 of households in America had a radio (history.com).
Some of the most famous speeches over the radio were given by the United States President Franklin D. Roosevelt. These speeches were called fireside chats and used by the President to speak to the nation during America's two hardships, the Great Depression and World War II. The radio is now in cars and used a lot for music. Today, the radio provides news and music to people around the world.
