History creation: 100th anniversary of public broadcasting
In many parts of the world, broadcasting is still the most important information channel for local people. On January 13, 1910, De Freest rotated the button to send kaluso's voice to the air on March 12, 1933, during World War II, the American family listened to the war news explorer In front of the huge radio- Depth Weekly reports in depth that the vast majority of people born before 1980s may have unforgettable memories of broadcasting. Before the TV era entered this ancient land in the 1980s S, broadcasting became the most important medium for hundreds of millions of people from cities to villages to obtain information and entertainment. The model drama of the Cultural Revolution era, the long commentary of the era of reform and opening up, and the 'weekly song' and other programs have profoundly defined the experience of our lives and the characteristics of the times. However, in just over 20 years, it took us a hundred years to finish broadcasting rapidly. The TV era swept through like a tsunami and has not yet waited for us to return to our senses, the Internet has occupied our lives again. This year marks the 100th anniversary of the birth of radio. We stand in a world where new information and images spread at the speed of light and look back on the world we lost. This may give us a little nostalgic homesickness in today's fast-changing era that is difficult to breathe. During the birth period, doubters questioned the obstruction of cow milk production. On January 13, 1910, Tano karuso was preparing to perform a new event: singing opera through radio waves and broadcasting his voice from the Metropolitan Opera House to every place in New York City. Inventor defrester has hung a microphone on the stage and side of the Opera House, installed a wireless transmitter and antenna, and turned the switch to make a magical sound. This evening opens an era where Radio Communications will provide instant long-distance wireless transmission for humans. The public's interest in broadcasting technology has increased day by day in the decade since De Freest broadcast. Amateurs become 'fans' of this new technology, not simply 'listeners '. 'Fans' means they not only receive broadcasts, but also transmit broadcast signals. Broadcasting has become a highly technical entertainment activity. Fans make receivers and transmitters at home with coils and spark plugs. Early broadcasts require very complicated dial adjustments, and not everyone likes to broadcast or knows how to use it. Doubters accused the broadcast of causing the spring bed to vibrate, the floor to creak and even the child to spit milk. In Wisconsin, people think that broadcasting can prevent cows from producing milk. In the glorious period, American family life, it is the absolute center, but the criticism did not stop the spirit of the radio fanatics. Although the U. S. government banned amateur broadcasting signals during the First World War, this new medium flourished after a short interruption. In 1922, the United States issued a business license to broadcasting companies and hundreds of radio stations were established. In the 1920 s, listeners found that Radio received information much faster than newspapers. The experimental Detroit 8MK radio announced the results of the presidential election to about 500 locals with receiving devices. As more and more events are reported on the radio, more fans build and buy radio devices. From January 1922 to January 1923, the number of radio devices in the United States increased from 60 thousand to 1. 5 million. In 1922, there were 28 operating radio stations, which increased to 1924 by 1400. The largest commercial radio stations are the National Broadcasting Corporation and the Colombian broadcasting system, which were established in 1926 and 1927 respectively, similar to today's TV network 'National Broadcasting Corporation '(NBC)And 'CBS '(CBS). The pioneer of non-commercial radio stations is what we call public broadcasting companies today. In the 1920 s, more than 200 colleges, universities and other educational institutions applied for broadcasting licenses, but 75% to 1933 of these radio stations were suspended. Although the huge economic crisis in 1929 temporarily suspended the development of broadcasting, the golden age of broadcasting had already begun by 1931. Half of American families have radios. The mother listens in the morning, the child listens after school, and the father and the whole family listen to the prime-time broadcast. Remote rural residents hear Buddhism and gospel music from their own kitchens. On 1932, the whole country stood by the Radio waiting for the latest progress in the kidnapping of American flying hero Charles Linbai. From March 12, 1933, every family listened from the kitchen to President Roosevelt's 'fireside talk' on Sunday night '. During the development period, there was no risk of passing through the media revolution. During World War II, 90% of families in the United States had Radios. They listened to the program for an average of 3 to 4 hours a day, making it their main source of news. By 1940, 1/4 of U. S. cars were equipped with radio. When the broadcast reached its peak, a new industry was born. In 1950s, people began to worry that with the arrival of television, the broadcasting era was over. The first crisis was education and non-commercial radio stations, and the donations they relied on now turned to TV. In 1964, Ford Foundation, the former major donor of education Radio, completely cut off its financial support. But the broadcast is not over and continues to prosper. The rise of rock music and the emergence of youth culture in 1960s made radio waves popular with listeners under the age of 21. In 1969, the national public broadcasting station funded by the federal government's public finance (NPR)Established. Over the next 40 years, NPR's radio station has expanded to the whole of the United States. Today, Defreest's experiment has passed in 100, and the Metropolitan Opera House will present our modern wireless miracle--- The Internet, but listeners and fans can still hear information and entertainment from the radio.
