When were radios invented?
Who invented radios?
What are their significance?
Did they help in WW1 and WW2, if so, how?
Please can you try to answer some of these questions,
I can’t find any helpful websites to find these answers.
If you do come across any good websites about radio and why it is significant then can you put it in your ’sources’ box!
Thank-you in advance

The original radio was called the ‘wireless telegraph’ and was used to send messages with dots and dashes, just like Samuel Morse’s device. An Italian named Gueliemo Marconi is/was usually credited with the invention of the radio/wireless telegraph, but he was sued for stealing Nikola Tesla’s work, and had to pay millions of dollars of damages to Tesla.

Later, voice and music was sent over radio, and that was a huge leap in entertainment technology, and, of course, military technology. Radio is the basis of both RADAR and something called the ‘proximity fuse’ which helped win WW II.
