In February 1896, Guglielmo Marconi developed the path for operational wireless technology. It all started with the existence of electromagnetic waves predicted by James C. Maxwell in 1860. By 1888, the existence of electromagnetic waves was experimentally proven by Heinrich R. Hertz.
The first experiment was held with a spark-gap transmitter with a receiver 2.4 km away, and it was successful. In the early days, wireless communication was advanced for military use only after various wireless technologies were developed and improved. These technologies were later expanded to broadcasting. With the rise of technological firms, radio broadcasting started in the first half of the 20th century. TV broadcasting was initiated in the second half of the same century.
