Slightly more than 100 years ago, on Feb. 17, 1919, station 9XM at the University of Wisconsin in Madison broadcast human speech to the public at large.
The cover page of the book “9XM Talking” by Randall Davidson.
9XM was first experimentally licensed in 1914, began regular Morse Code transmissions in 1916, and its first music broadcast in 1917. Regularly scheduled broadcasts of voice and music began in January 1921. That station is still on the air today as WHA.
