As technology advances and new ways of performing tasks and new equipment are developed, they are applied to other mechanisms to make things easier. Technological change applies to almost everything in our lives. Of course we have made a big leap from riding in horse carriages to riding in cars or from switching tapes in cassette players to downloading applications on our iPod Touch. All these changes make an impact on society. Technological change is the cause of many progressions on the modern world as well as in the media.
In 1896 Marconi developed a radio transmitter that allowed radio waves to carry Morse code to other places. Ten years later, De Forest invented the vacuum tube that amplified and carried voice, sounds and music to be broadcasted. These technological changes ultimately led to major broadcasts and thus started the evolution of radio broadcasting. In the early 1920s broadcasting stations like NBC were created and the rise of radio began. The technology of radio emerged and merchants began advertising on the radio, shows were created for entertainment and news was available to all with a radio. Without technological change, we would still be listening to a radio instead of surfing the internet, or watching broadcasting on TV.
