4 March – The Courier, the first seagoing radio station, is dedicated by United States president Harry Truman.
21 March – The Moondog Coronation Ball is hosted by star deejay Alan Freed and WJW (AM) in Cleveland, Ohio (modern-day WKNR) at the Cleveland Arena. Among those scheduled to perform at the event were Paul Williams and the Hucklebuckers, The Dominoes, Varetta Dillard and Tiny Grimes, but only the Hucklebuckers are able to perform before the concert is shut down by officials. So many tickets were counterfeited that the 12,500 seat Arena now had 25,000 people in attendance, alarming Cleveland Police Capt. William Zimmerman, who stopped the show. A near riot ensues when close to 7,000 additional fans, unable to buy tickets, rush the gates and storm into the arena. Freed and WJW gain national attention and prestige, and the event is now universally recognized as the first rock 'n roll concert.
28 August – DXCC in Cagayan de Oro, Philippines officially signs on the air, and becomes the first radio station of what becomes known as Radio Mindanao Network.
