Today in 1915, David Sarnoff, Chief Inspector for The Marconi Wireless Telegraph Company of America (and later CEO of RCA and NBC), suggested to his superiors music broadcasting by radio.
Sarnoff:
I have in mind a plan of development which will make radio a ‘household utility’ in the same sense as the piano or phonograph. The idea is to bring music into the home by wireless. The receiver can be designed in the form of a simple “Radio Music Box,” placed on a table in the parlor or living room.
Sarnoff may have actually written this memo in 1920, but later claimed it was written before 1916, the year Lee De Forest and others started broadcasting news and transmitting music over the wireless to multiple recipients.
