Starting in 1896, when Guglielmo Marconi invented the “wireless telegraph” that used radio waves to carry messages, the radio industry has been an essential part of the media, constantly progressing as a result of technological change. In fact technological change is the main force that shaped the evolving radio industry in the 1920s. Technological changes in the 1920s and the years that followed strengthened the radio industry, allowing it to become a phenomenon that is still a part of our everyday lives.
Technological progress is an important factor of every potential industry. Improvements and changes in technology allow for an industry to grow in any circumstance. From less costly and faster ways of production, to a more improved resulting product, technological change is necessary for any industry's success.
Marconi’s invention kicked off the radio industry’s intensive play in media. Starting as a form of communication between radio stations and oceangoing ships, the radio soon became a part of everyday life. Lee de Forest speeded this process by inventing the vacuum tube, which allowed for radio transmission and reception of sound, voice, and music. Soon many more technological improvements would make the radio as David Sarnoff once saw it: “a household utility” that would bring music into the house by wireless. However it wasn’t only music that dominated the radio, it also included news, variety shows, soap operas, dramas, and sports. The radio progressed even further through the FM, which has high-fidelity sound, that allows for more stations in each market. As music diversified, more FM stations were developed in order to satisfy the many different tastes. As a result, marketers were able to target different subcultures through specific radio formats. This is yet another example of radio progress through the technological developments; these developments reduced the price of recordings and the cost establishing radio stations. This pattern of progress continued with the development of satellite radio, which offers hundreds more channels, and Internet radio, which list thousands of radio stations for listening. Furthermore, podcasting allows individuals to create audio programs that can be downloaded. High definition radio further improved the quality of broadcasting, making the whole listening process more enjoyable.
Although the radio industry has to compete with other technologically developed industries like television and the Internet, it is still a prominent aspect of media and a part of many people’s lives.
