During the following years, radio broadcasting in Argentina saw a quick expansion. In 1921, Buenos Aires mayor Juan Barnetche introduced official broadcasting licenses. In the same year, Radio Club Argentina was founded, becoming the first such association on American soil. In October 1922, Radio Argentina broadcast live from the inauguration of president Marcelo Torcuato de Alvear, an historic first. Two months later, the first competitors arrived - Italian-owned "Corporación Argentina de Radio Sud América", "Radio Brusa" and "Radio Cultura", all three founded within an interval of three days.
