Today in 1919, the first transmission of music by radio waves.
“The radio department of Rockwell field at San Diego gave a treat to music lovers February 2 [1919] which, so far as is known, was never tried in the world before. The treat was entitled ‘Moonlight Witches Dance,’ the music coming from the battleship Marblehead transmitted by wireless telephone… The apparatus was tuned so as to sound as if the music was in the house, and not miles away… A perfect reproduction was made of tones from the Victrola aboard the Marblehead, the volume of tone being greater than the musical instrument itself”–Music by Wireless, Telephone Engineer, March 1919
In the second quarter of 2022, the number of music streaming subscribers worldwide reached 616.2 million.
