One of the most influential people in the history of the radio is Guglielmo Marconi, an Italian inventor. Over the course of a few years, starting in 1894, he built the first completed commercially successful wireless telegraph system based on airborne waves (radio transmission). Marconi demonstrated the usability of the radio for military and naval purposes and launched the company to develop and distribute radio communication services and equipment. In 1896, he conducted the first public demonstration of his equipment, achieving the transmission of radio messages over a distance of 2.5 km.
Marconi believed that electromagnetic waves could pass through soil and water without losses. This erroneous point of view had a considerable influence on the further development of radio engineering. In fact, the losses due to the passage of radio waves through the soil and water are enormous. However, short radio waves can be reflected from the ionosphere and go around the entire globe. Therefore, this hypothesis allowed Marconi to organize the first radio communication across the Atlantic Ocean.
One of the most essential stages in the existence and development of radio was its first commercial launch. This happened in 1920: the KDKA station in Pittsburgh held the first broadcast dedicated to the election. This broadcast was from a wooden shack in east Pittsburgh. The presenter discussed the election results, turned on the music, and tried to communicate with the audience. This event formed the basis of the current commercial activities of radio stations.
One of the prominent representatives of the radio industry is Michael Francesa, an American sports radio talk show host. During his career, he worked in various programs, including his own shows. Thanks to his sincere interest in sports, Michael always did his job well and won the hearts of the audience. He had a significant impact on the broadcasting industry in the field of sports, developing both the quality of radio programs and the interest of the audience. He continues to conduct various shows to this day, remaining professional and involved.
