Guglielmo Marconi invented a machine in 1902 that lets us listen to music and get the daily news report. It became popular in the 1920s. It’s called the radio. How has radio influenced us today? We are able to turn on the radio anytime during the day to get updates on news events that happen in the world. We are able to listen to music to entertain us at home or while driving in our cars. How does the radio work? The radio does rely on batteries or a power source to work. In 1902 the radio uses energy that is provided to the antenna. This requires long wires for receiving signals from remote stations. This caused problems with receiving certain frequencies. Then in 1903 the inventor began to use high frequency alternators to send radio waves. Radio became popular in 1923 when they started broadcasting culture, education, information, and some entertainment. Today radio is used for many of the same things. We get to listen to the latest music, advertising for new products, news and weather updates. Without radio today we wouldn’t get much information or music while driving.
