In short
On December 24, 1906, Reginald Fessenden broadcast the first radio transmission of music and voice from Brant Rock, Massachusetts—a moment that transformed radio from a curiosity into a medium for mass communication. The broadcast reached ships at sea and a handful of listeners with crystal radio receivers, proving that wireless transmission could carry entertainment, not just telegraph signals. This single transmission sketched the blueprint for commercial radio as we know it.
How it unfolded.
The five-minute version
What actually happened.
The history of radio had many contributors, beginning with the scientific discovery of electromagnetic radiation in the late 1800s, followed by technological development of improved devices for producing and receiving transmissions.

"Wireless Telephone Transmits Music Across the Ether"
Synthesized from period reporting - A remarkable demonstration of wireless telegraphy took place last week when musical selections were successfully transmitted without wires, marking a stunning advance in electrical science. The feat suggests that the human voice and instrumental music may soon travel through space as readily as telegraph signals.

"American Experimenters Achieve Wireless Music Transmission"
Synthesized from period reporting - Despatches from across the Atlantic report that American inventors have succeeded where European scientists have merely theorized, broadcasting musical performances via wireless apparatus. The development represents a bold step toward commercial wireless telephony.
