When Was the Radio Invented?
Tesla applied for his first patents in radio work in 1897 in America. He also built and demonstrated a radio-controlled boat at Madison Square Garden in 1898.
Here's where things get sticky in the world of wireless communication.
In 1900, the U.S. Patent Office granted Tesla patents 645,576 and 649,621 (the fundamental design of the Tesla coils) on March 20 and May 15, respectively.
Tesla's radio patents gave him ownership over one of the key necessities in radio communications.
Who invented television
That same year, on Nov. 10, Marconi filed patent No. 7777, for tuned telegraphy.
At first the patent office denied Marconi's applications on the grounds that his work relied on the use of Tesla coils [source: PBS]. Unfazed, Marconi used his father's connections and wealth to spearhead a profitable business based on his telegraph technology while continuing to pursue his radio patents.
In 1901, he transmitted the first transatlantic telegraph.
Marconi reapplied for three years while he gained financial support from company investors Andrew Carnegie and Thomas Edison. Finally
