[2] Radio broadcasting enjoys a long and varied history in Argentina, tracing its origins to a 1910 stay in the southside Buenos Aires suburb of Bernal by Guglielmo Marconi, inventor of the wireless telegraph.
Argentine publisher José C. Paz later sponsored Marconi's radio transmission from Italy to Buenos Aires, the first transatlantic broadcast into South America.
Among the notable events broadcast live at the time was President Marcelo Torcuato de Alvear's inaugural, in 1922, and the 1923 "bout of the century" in Polo Grounds, New York City, between Jack Dempsey and Luis Ángel Firpo for the World Heavyweight title.
[4] The medium's boom and the lucrative local ad market allowed Susini to sell his station in 1930 to U.S. telecom giant ITT for US$200 million, a record at the time.
[7] The trend was not without its detractors, however, and in 1943, the newly installed dictatorship of General Pedro Ramírez banned humor which "deformed the language," leading to exile for Marshall and numerous other radio stars.
The Comité Federal de Radiodifusión (COMFER) was established in 1972 to both regulate the growing number of unlicensed stations, as well as to increase state influence over the medium.
The return of democracy in 1983 led to an unprecedented selection of news programs, and many became known for muck-raking exposés; some of the highest-rated included Magdalena Ruiz Guiñazú, Santo Biasatti, and Nelson Castro.
Football remained a perennial favorite on the Argentine radio, and some of the best-known announcers have included Fioravanti, José María Muñoz, Enrique Macaya Márquez, Horacio Pagani, Marcelo Araujo, and Víctor Hugo Morales, among many others.
