Their chief amusement was picking up on crude, home-made receiving sets the wireless-telephony messages, principally from ships at sea, which symbolized the quarter-century advance in communications since Marconi's experiments in the 1890's.1 Broadcasting grew out of this amateur activity. When experiments were made in putting news and music on the air, the realization grew that this new medium had startling potentialities for entertainment. They had been foreseen some four years earlier by David Sarnoff, ambitiously planning a "Radio Music Box" for every home, but apart from a few limited demonstrations it was not until 1920 that broadcasting in its modern sense became an actuality.
Among the experiments with music in that year, those of Lester Spangenberg, a former navy radio operator, have been credited with constituting the first regular broadcasting.
