Foreword: In 1906, radio allowed mankind to communicate across the boundaries of time and space for the first time, and it was possible to broadcast the fireside chat of US President Roosevelt, and in 1949, the founding ceremony of the People's Republic of China was spread all over the land of China through broadcasting. Who still listens to the radio? You're wrong! Broadcasting in the car is the friend who knows you best, broadcasting at night is the most faithful companion, and broadcasting is the bravest witness in the face of emergencies. Want to replace radio? It's not that easy!

The birth of radio

On Christmas Eve 1906, Freisendon and Alexanderson in the United States set up a radio station near New York and broadcast for the first time ever. The broadcast consisted of two jokes, a song and a solo violin piece. The radio program was clearly heard by the people who were scattered around at the time with receivers.

In 1908, Forrester of the United States made another broadcast on the Eiffel Tower in Paris, which was heard by all the military radio stations in the area and by an engineer in Marseille.

In 1916, Forrester broadcast news about the presidential election at an experimental radio station in the Bronx Press Bureau, but only a handful of people at the time were able to listen to these early broadcasts.

Real radio was born in the 20s of the 20th century.

The world's first licensed radio station was the KDKA radio station in Pittsburgh, USA, which was officially launched on November 2, 1920.

China's first radio station was established in January 1923 by Osbon in the United States, which belonged to the China Radio Broadcasting Corporation, and was first broadcast in Shanghai.

In 1926, China's first self-run radio station, Harbin Radio, was founded by Liu Han.

In December 1940, the Chinese People's Broadcasting Industry was established, that is, the predecessor of the Central People's Radio, Yan'an Xinhua Radio.

Advantages of broadcasting

Auditory information

Radio is transmitted by sound. The charm of sound lies in the fact that it not only disseminates information, but also integrates this information into the understanding of the communicator, so as to help people understand and receive information, and guide them. The host's style of hosting the program and his grasp of the program can greatly enhance the attractiveness of the program. Their re-creation and improvement of manuscripts can have a great impact on the audience's knowledge, understanding and acceptance of information.

The charm of using sound as a communication feature also lies in the fact that radio is suitable for everyone, regardless of the age or level of education of the audience. Broadcasting is also mobile and portable. People can keep up to date with the latest information from the radio at any time, anywhere, and conveniently.

It's fast

First of all, the speed at which broadcasts travel is fast. Speed is one of the great advantages of the Internet, which is faster than broadcasting for general information processing. However, for major events and important news, radio spreads faster than the Internet. In other words, the speed at which news is targeted by a broadcast reporter can be almost equal to the speed at which the event progresses.

The popularity of mobile phones has greatly improved the timeliness of radio programs. At the scene of news events, broadcast reporters only need to have a telephone, they can see six channels, listen to all directions, observe, interview, think, and broadcast orally, send the signal directly into the live broadcast room, and report the progress of the news event to the audience in real time; At the same time, it can also make all kinds of sound on the scene, such as the conversation of characters and natural sound, directly into the sky. Broadcasts can also be broadcast live, from which listeners can follow the progress of news events in real-time.

Trends

The 21st century is the century of the web. In the last few years of the 20th century, as soon as the Internet landed in China, it appeared as a powerful media, with rapid development momentum and wide social influence. In May 1998, the United Nations Committee on Information formally proposed that the Internet should become the fourth media after newspapers, radio and television. By the year 2000, the media with a certain influence in China had "touched the Internet" one after another, so much so that this year was called the "Internet Year" of the news media.

The application of the three major technologies in the information age, digital technology, network technology, and satellite technology in the media has made the broadcast media the biggest beneficiary, and has also enabled the broadcast to achieve "wide dissemination" in the true sense.

If radio wants to get rid of the disadvantageous situation of today's weak media and seek great development, it is obviously not possible to make small troubles, make partial adjustments, talk about programs on programs, and talk about radio broadcasts. Digital technology, network technology and satellite technology have provided sufficient technical support for the rebirth of broadcasting. At present, the time is ripe for a comprehensive reform of radio in the areas of interviewing, editing, transmission, production, broadcasting, listening, and storage, and the conditions are already in place.

The sound quality of digital audio broadcasting is as pure as a laser turntable, which makes the entertainment function of broadcasting more perfect; Moreover, digital audio broadcasting is very anti-interference, and there is no noise when listening on the move, which meets the new needs of people listening on the move. Digital tools and equipment are constantly emerging in the interviewing, editing, production, and broadcasting of broadcasts. In March 2000, the World Broadcasting Satellite "Asia Star" was successfully launched, and one beam of Asia Star covers an area of 140 million kilometers, which can cover the entire territory of China. People in the service area of the World Radio Satellite can listen to the radio directly from the satellite with only a small receiver. The "wide reach" of radio is no longer a difficult task.

Network technology has created a new transmission method for broadcasting - network broadcasting, and built a solid platform. The convergence of broadcasting and the web has become a trend.

Broadcasting on the Internet has expanded the reach of broadcasting and compensated for the inherent shortcomings of broadcasting: linear, fleeting, unpreservable, unsearchable, and invisible. Network broadcasting combines the advantages of the Internet and audio broadcasting, so that radio programs can be saved, textual, on-demand, retrievable and downloaded at will, and greatly increase the amount of information. With the development of broadcasting technology, network radio will truly highlight the characteristics of personalized services, provide specific services for specific audiences, and realize interactive and interactive broadcasting with listeners.
