In the History of Media unit, I learned that Guglielmo Marconi was an Italian inventor who proved radio communication. He also sent and received the first radio signal in Italy in 1895. By 1899, he flashed the first wireless signal across the English channel.

Radios emerged as a machine service durning WWI. Soldiers use radios to communicate with each other & it also helps them target their enemy. Radios are a very useful tool for everyone.

Radios come in handy when you're not at home & you're driving. You can hear news broadcasts through the radio if you're not able to hear it from a television.
