2 janv. 1920 - Invention of AM Radio

Description:

While radio transmissions began in the early 1900s for military purposes. However, in 1920 KDKA in Pittsburgh and WWJ in Detroit went on air blending news and live music. This was the first time people with a radio signal could listen to music that they never had access to before.
