The invention of radio had a powerful impact on society because it allowed wireless communication from distant locations for the first time in history. Moreover, the radio allowed information to be transmitted in multiple locations at the same time.
Before the invention of the radio, the only means of communication for long distances was the telegraph, but this was a wired system and it required people to be dependent on operators to communicate. The radio also changed the way people received their news and it became one of the first mass entertainment media in history. The precursor of television, radio offered people access to music, theater plays and daily news in a way unknown before.
