2. The Inventor of the radio was Guglielmo Marconi. He proved that his invention had worked when he proved that he could send radio communications because of the signal’s feasibility. Although Marconi was the first to invent the radio, Nicola Tesla took out patents on it first. Nicola Tesla was considered to be the first to patent the object.

3. 1899 – Marconi sent he first feasible radio waves for communication 1902 – Tesla patents on Marconi’s invention Transmitters called spark- gaps were used to send messages Alexanderson high frequency alternator and De Forest tube conquered technical problems

4.  Hertz – Built an antenna and a high voltage capacitive spark discharge. This signified the detection of radio waves.  Nicola Tesla – He used a high voltage transformer in radio wave technology, known as the Tesla Coil.  Alexander Papov – He built a radio receiver into the radio, known now as the lightning detector

5. Since the radio was put out on the market, people were always looking to buy one, and since then the radio has continued to evolve since then.

7.  The invention of the radio and continued to be remade and remodeled to fit the society.  It began from having just one station to having many stations.  The radio is still developing as time goes by.
