 In the years immediately after its development in the late 1890s, radio communication remained completely unregulated in the United States.On November 3, 1906, U.S. representatives meeting in Berlin signed the first International Radiotelegraph Convention, which called for national licensing of radio transmitters.This proposed treaty was brought before the U.S. Senate for ratification in early 1908, but in the face of strong opposition by the largest radio companies it was unable to gain approval.
