Entertainment in the 1920s
In the mid-1920s, there were two technology that changed everyone's livestyle: radio and television.
The radio broadcasting began in 1920 with historic broadcast of KDKA. Few people actually heard music and voices in the radio. Between 1920 and 1930, 60 percent of American families purchased radio. Families gathered around their radio for night-time entertainment. In 1920, the KDKA was not the only operating radio station, but it remains a benchmark in most accounts. And by 1922, 60 radio stations had sprung in the United States. In the mid-1920, the radio stations began broadcasting things such as popular and classical music, sport events, lectures weather reports, stock market updates, and political commentary.
Scientists from around the world worked to perfect television for decades. American inventor named Charles Francis Jenkins transmitted an image of Herbert Hoover, the Secretary of Commerce, from Washington to Philadelphia by radio in 1923, and he demonstrated a mechanical television scanning system by using a revolving disk in 1925. He called it "radiotelevision." However, Jenkin's invention was very slow and its images were murky. In the mid-20s, Denes von Mihaly of Germany,Kenjiro Takayanagi of Japan, and John Logie Baird of Scotland designed various system, but none of them is seen as the "inventor" of TV. However in 1927, a 21-year-old named Philo Taylor Farnsworth invented what is called the "image dissector." As a youngster growing up in Utah and Idaho, he read magazines about the idea of broadcasting the image and sound, becoming fasinated that he studied molecular theory and electricity. His work led him to invent the first electronic television system.
