It was invented by Guglielmo Marconi in the 1890s. Before the radio was invented, news travelled very slowly. Long-distance messages could not be sent quickly. In 1901, a radio message was sent across the Atlantic Ocean for the first time. After that, news can be spread all over the world in seconds. Besides, many other inventions were developed because of the radio, such as televisions. It also changed music: works of artists from different countries can be enjoyed by everyone easily. The radio breaks the limit of distance and connects people closely. It shows how powerful creative ideas are. Without it, we would never get information so quickly. It is truly a life-changing invention for human beings.
