Full Answer

Marconi went on to establish three companies named American Marconi, British Marconi and Canadian Marconi; these companies imposed a ban on using his invention to communicate with rival technologies.

Orders for his radio rose in the aftermath of a preventable boat tragedy. This led Marconi to open a factory dedicated to building radios in Chelmsford in 1912. During this time, amateurs and hobbyists started broadcasting using improvised equipment. When the United States joined World War II, it imposed a ban on all amateur radio stations and recruited the operators into the army.
