At the beginning of the 20th century, several researchers and inventors began to develop wireless communication systems. In 1901, an Italian inventor named Guglielmo Marconi successfully transmitted a radio signal across the Atlantic Ocean between England and Canada, proving that long-distance wireless communication was possible. In the same year, Marconi also conducted an experiment by sending radio signals across the English Channel.

Over the next few years, radio technology continued to grow. In 1906, a Canadian engineer named Reginald Fessenden made the first radio broadcast incorporating the human voice. He became one of the pioneers in the development of radio as a medium of broadcasting.

In the 1910s and 1920s, radio became increasingly popular as a means of communication and entertainment. Radio stations began to appear in various countries and people could listen to the radio broadcasts widely. In 1920, the first commercial radio broadcast took place in the United States.

In the 1930s, radio became one of the main world media with entertainment, news and sports programs. During World War II, radio was also used as an important military communication tool.

After World War II, the development of radio continued. In 1945, United Nations Radio began broadcasting to convey information and news about the United Nations. In the 1960s, FM (Frequency Modulation) radio technology emerged, which provided better sound quality than AM (Amplitude Modulation) technology.

In the 1970s and 1980s, developments in semiconductor and computer technology changed the face of radio. Radios started using digital technology and became smaller, more portable and had additional features such as cassette and CD players. In the 1990s and 2000s, with the advent of the Internet, radio was also accessible online through audio streaming.

So far, radio remains one of the most popular media in various countries. Even though technological developments have brought advancements such as satellite radio and internet radio, conventional radio with AM and FM broadcasts is still the choice of many listeners, even though it is slowly becoming obsolete.
