2. Origins
The early history of radio is the history of technology that produce and use radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio.[1] Radio development began as "wireless telegraphy".[1] Later radio history increasingly involves matters of broadcasting.

3. Gugliemo Marconi
German scientist Heinrich Hertz proved the existence of radio waves, which occur in nature. In 1895, a young Italian named Gugliemo Marconi invented what he called “the wireless telegraph” while experimenting in his parents' attic.

4. How it works
Radio waves" transmit music, conversations, pictures and data invisibly through the air, often over millions of miles -- it happens every day in thousands of different ways! Even though radio waves are invisible and completely undetectable to humans, they have totally changed society. Whether we are talking about a cell phone, a baby monitor, a cordless phone or any one of the thousands of other wireless technologies, all of them use radio waves to communicate.
