Radio Belgrado, uno dei più antichi media elettronici d’Europa, ha iniziato a trasmettere in questo giorno 100 anni fa

The experimental broadcast of Radio Beograd-Rakovica started on September 19th, 1924, from the building in the picture (42 Knez Mihailova Street, the building built for the Belgrade office of the First Croatian Savings Bank in 1922; still in existence today). Engineers Mihailo Simić and Dobrivoje Petrović broadcast the first test concert through a transmitter in Rakovica, then a village near Belgrade, now an urban neighbourhood of the city. Ksenija Rogovska sang an aria from “Tosca,” Žika Tomić performed Stevan Hristić’s composition “Behar,” Karel Holub played Mendelssohn’s “Violin Concerto in E minor,” and pianist Velizar Gođevac played two Chopin etudes. Vitomir Bogić recited the scene “Under the Balcony” from Edmond Rostand’s Cyrano and sonnets by Jovan Dučić.

The regular broadcast started October 1st, 1924.

Radio Beograd AD replaced Radio Beograd-Rakovica on March 24th, 1929.

I think I have read that it was the radio wave that had the widest radius in WW2 for the Axis powers, so that even German soldiers in Northern Africa were listening to Radio Belgrade. The wave is also famous for popularising the song Lili Marleen.
