August 20, 1920 –
The first commercial radio station begins operating in Detroit, Michigan with call sign 8MK (Now WWJ (Newsradio 950) ).
The radio station was started by The Detroit News newspaper and is now owned and run by CBS.
To celebrate the event, National Radio Day, UNESCO formally announced the formation of International Radio Day in February of 2012 (celebrated February 13th), after a suggestion put forward by Spain to celebrate this important means of communication. In some parts of the world, radio still remains an important lifeline to the outside world.
And so it goes
