How to use the urbanized society to develop the radio advertising business?

Driven by two major historical events, the broadcasting industry has developed significantly. These two events were World War I and World War II, and the War of Liberation in China.

1.World War I and World War II:

During the interwar period, radio, as a new form of media, developed enormously. During World War I, the Canadian Phisington and the American Devstrray were among the best examples of the early experimental radio stations, and during the Second World War, radio became an important source of information, comfort and entertainment. Broadcasting during this period not only made a breakthrough in technology, but also reached new heights in terms of influence.

2.China's War of Liberation:

During China's War of Liberation, the broadcasting industry also underwent tremendous changes. The main part of the radio stations in New China was renamed from the Xinhua Radio stations in the revolutionary base areas, for example, the People's Radio Station was renamed from the "Xinhua Radio Station in Beiping" on December 5, 1949. In addition, during the Liberation War, Yan'an Station was also renamed "Xinhua Radio Station in Northern Shaanxi", and followed the *** to fight in various places, becoming a sharp weapon in the struggle against the enemy.

In general, these two major historical events have played an important role in promoting the development of broadcasting, not only in terms of technology and scale, but also in terms of influence and social status of broadcasting.

On Christmas Eve 1906, Fresenden 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, the American Forrester 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 1926, China's first self-run radio station, Harbin Radio, was founded by Liu Han.

In 1928, the Chinese Kuomintang succeeded in the Northern Expedition and established the "Chinese National Executive Committee Radio Station" in Nanjing, with the call sign XKM.

Radio broadcasting refers to the news transmission tool that transmits sound through radio waves or wires, and was born in the 20s of the 20th century.

Among them, the transmission of programs through radio waves is called wireless broadcasting, and the transmission of programs through wires is called cable broadcasting. The advantages of broadcasting are that it has a wide range of objects, rapid dissemination, diverse functions, and strong appeal; The disadvantage is that it is fleeting, listening sequentially, you can't choose, and it is difficult to listen if you don't understand the language.

Now, broadcasting has achieved the strategic goal of focusing on frequency modulation, medium wave, and supplemented by short wave, which is a major change in the history of international broadcasting.

Domestic, you can take a look at Zhao Yuming's general history of Chinese radio and television. I'm sorry, but I haven't seen a very complete book abroad.
