(0.8pt) Guglielmo Marconi is the person who generally gets the credit for inventing the radio. He began experimenting with wireless communication in the attic of his father's villa in Italy. In 1895, he sent a wireless signal one and one half miles. Marconi found that England was interested in his discovery. They hoped to use it for communication with ships at sea. So, in 1896, Marconi moved to England and began his Wireless Communication and Signal Company. By 1899, he was able to send a signal across the English Channel, a distance of 31 miles. At the same time, an inventor in the United States, Nikola Tesla, was also experimenting with wireless communication. As early as 1893, he had experimented with the technology and conducted demonstrations and lectures on the subject. Unfortunately, his progress was slowed when a fire destroyed his laboratory.
