Who invented the FM radio?

Big debate over this one. It was either a fella named Marconi, or another fella named Teslsa (not the sucky band named Tesla). Before you can answer "How", you have to decide "who", because the 2 camps believe very different things. Nikkoli Telsa was a genius, with several unique inventions to his name, some of which have been tied to military use (rainmaking). Marconi, on the other hand, was slow to get to the patents office with his invention, which consisted of a device had only a two-circuit system, which some said could not transmit "across a pond." Later Marconi set up long-distance demonstrations, using a Tesla oscillator to transmit the signals across the English Channel. Tesla was embroiled in other problems when Marconi won the Nobel Prize in 1911, Tesla was furious. He sued the Marconi Company for infringement in 1915, but was in no financial condition to litigate a case against a major corporation. It wasn't until 1943
