The world's first radio Radio

"Warren Harding defeated James Cox by an overwhelming advantage and was elected the 29th President of the United States."

This news comes from the world's first radio broadcast station-KDKA Radio.

This was an amazing success. The establishment of wireless radio stations enabled people in Pennsylvania, Ohio, and West Virginia to listen to the news at the same time. The mass communication of mankind also opened a new chapter.

"The medium is a huge social symbol that not only conveys information, but also tells people what kind of world exists. It changes our personality by changing the proportion of our use of sensor systems."

Since the KDKA radio station in Pittsburgh, USA officially started broadcasting in 1920, radio broadcasting around the world began to emerge. However, at that time, the frequencies of radio broadcasting in various countries were in the medium wave and long wave bands. After amateur radio enthusiasts discovered that shortwaves below 200 meters have long-distance transmission characteristics in 1921, radio broadcasting soon opened up the shortwave band. In 1933, American scientist Armstrong invented frequency modulation technology. Commercial FM broadcasting was first started in the United States in 1941. Since 1962, FM stereo broadcasting has emerged in the world. Since then, people have ushered in a new era of radio broadcasting with high fidelity that is free from the interference of sky and electricity noise.

"The most fundamental thing about electronic media is not to influence us through content, but to influence the "scene geography of social life." 

The advancement of science and technology and the pursuit of higher quality of life have made human beings no longer satisfied with the enjoyment of hearing. Media such as television and the Internet have emerged one after another, and the meaning of media has been redefined time and time again.

Mass media has the power of information environment, and it restricts people's behavior through people's environmental cognition activities. This is the main mechanism for mass media to exert its social influence. With the continuous development of media and the continuous improvement of technology, mass media has an increasingly profound impact on people's lives in contemporary society. In the economic, political and social fields, mass media also plays a more important role. At the same time, the development of mass media also promotes the transformation of society and the progress of urban economy.

"The media plays an indispensable role in enhancing the competitiveness and influence of a city"

The emergence of a new medium will lead to the birth of a new civilization. The development of the media industry not only drives the growth of the city's economy, but also shows the rich connotation and broad extension of a city. In addition, the "marriage" between cities and mass media is also a new starting point for the development of mass media. As the integration of mass media resources continues to deepen and optimize, various media are increasingly integrated. While achieving complementary advantages and resource sharing, it has also promoted the upgrading of the mass media industry.

Nowadays, the mass media has become one of the drivers of the urbanization process, and its rapid development has also accelerated the development of the city to a more scientific and civilized field.
