    The first radio: Disadvantage
    This was the very first radio ever invented in 1893 by Nikola Tesla & was a huge step up from anything yet made. The radio refers to either the electronic appliance that we listen with or the content listened to. However, it all started with the discovery of "radio waves". This is a disandantage beacuse the more time people will be spending listing to the radio, the less time they will be spending with their family. http://www.electronics-radio.com/articles/history/radio-receivers/radio-histor

  • First FM radio: Advantage

    First FM radio: Advantage
    Edwin Howard Armstrong develops frequency modulation, or FM, radio as a solution to the static interference problem that plagues AM radio transmission, especially in summer when electrical storms are prevalent. Rather than increasing the strength or amplitude of his radio waves, Armstrong changes only the frequency on which they are transmitted. The new FM radio is less prone to interference than AM radio. But AM radio doesn't have any sound barriers like FM. http://www.diffen.com/difference/AM
