Thelen1 ABSTRACT The invention of radio broadcasting has had the most significant impact on society in the  last 100 years. The invention of radio broadcasting has led to better communication of orders to  troops on the battle field. Radio broadcasting has led to a new way to bring entertainment and  news to the general public. The invention of radio broadcasting gave birth to the field of  engineering by leading the way to innovations that lead to further advancements of broadcasting. Leading to better communication, broadcasting entertainment and news, all while giving birth to  engineering are all reasons that the invention of radio broadcasting has had the most significant  impact on society in the last 100 years. Thelen2 INTRODUCTION The invention of radio broadcasting has had the most significant impact on society. Radio broadcasting has created a new medium for entertainment and advertising to reach consumers.  Before, music was spread through word of mouth and sold on records, now they could be sent  across the airwaves and anyone could listen. Along with music, now businesses could essentially sell their products by broadcasting their company and the information about their product. Radio  Broadcasting has also made it easier for military leaders to contact and give orders to troops on  the ground. Furthermore, radio broadcasting essentially gave birth to electronics. The history of broadcasting has deep roots in early communication. The radio was  developed after the telegraph. Also the impact of radio broadcasting on the world as a whole is  greatly significant. The invention impacted the general public in the sense of receiving  entertainment and news in the home. The invention of radio broadcasting also impacted the  world with its military capabilities of allowing troops to communicate with superior officers. HISTORY OF BROADCASTING The history of the radio, and therefore, broadcasting begins with the telegraph. An  invention in the early 1800s that used short electrical signals and a closed wired system to  communicate across circuits across the United States. The discovery of radio waves allowed the  telegraph to come off the wired system so it could communicate with ships and planes. Soon  enough it was discovered that using radio waves, one could send vocal communications. This  was seen as invaluable during World War I, especially in espionage and propaganda.  In 1904 the United Fruit Company hired Lee De Frost to build radio stations in order for  shipping companies to better communicate in order to transfer nonperishable goods to the United Thelen3 States. In 1907 Lee patented an arc radiotelephone transmitter and an audion receiver. Lee would later improve on his design and create the Radio. (Marc, 2000) During World War II so many people were using the radio to broadcast their own music.  The government banned all public broadcasting for fear of the enemy intercepting  communication. After the radio gained much popularity, investors began imagining the potential  of broadcasting and put their money in advancing the technology. SIGNIFICANCE The invention of radio broadcasting can be discovered in different branches of its  applications and uses. Most importantly, radio broadcasting found a large home in military  applications in the field. Along with military applications, radio broadcasting also found major  significance in reporting news and entertainment, it’s also the birthplace of electronics. Military Applications The Invention of radio broadcasting has led to better communication between troops,  naval vessels, and air craft. Before radio broadcasting, before even the telegraph, army generals  had to use couriers to send messages to leaders of different groups of soldiers. These commands  could take days. With the invention of radio broadcasting. Orders could be sent directly to  leaders and even soldiers on the ground instantaneously. This lead to wars being won because  orders could be received and carried out in a matter of seconds. Not only did ground troops benefit from broadcasting, but aircraft could be given orders  as well and also be notified of any incoming aircraft. Broadcasting was used to notify aircraft  bombers of targets that they were to bomb and were to leave alone. Along with being given  Thelen4 orders, broadcasting allowed officials to be notified when an aircraft was shot down. This was  also a benefit on naval vessels. A radio broadcast could send the message and location that a ship was sinking or was in danger. Radio at Home Radio Broadcasting led to a new wave of introducing entertainment and news to the  general public. During world war II, news about how the troops were doing the movements of  the Nazi party was broadcast to the united states. June 14 it was broadcast on German radio that  the Nazi party had invaded Paris and the city was theirs (Gordon and Falk, 1967). Along with  this news, war propaganda was spread. War propaganda promoted goodwill to whoever was  broadcasting it and ill will towards whoever the enemy was. This kept up moral in the people of  the occupying state as well as the troops to hear how evil the enemy is and how good their cause  was (Marc, 2000). Along with spreading news and propaganda in a whole new way, radio broadcasting also  sprung a new way for artists to spread their music. When radio first came to be and thousands of  homeowners had a radio station that they used to spread their voice across the airwaves. Some  began realizing that they could play music. When this trend began the FCC (Federal  Communications Commission) was formed and began delegating bands of airwave frequencies  to big corporations. It then became a common goal for radio to entertain the  masses( These radio stations would broadcast everything; news, sports, music, radio shows, anything that could be described. The aspect of music became a big focal  point for most radio stations. Bands came sprinting to radio stations to get their music out to the  public. Thelen5 The Grandfather of Electronics Radio gave birth to the electronic age. After the radio was invented and began broadcasting  across the nation, big investors wanted to innovate the technology further. The big push was  when a scientist successfully televised an image of the US dollar to London. Two big companies  chopped at the bit to perfect this new system, General Electric and Westinghouse. At first, the  technology to transmit images to a television was a revolving disk but the technology  implemented in the radio, the electronic tube system, turned their attention away from the disk. ENGINEERING SIGNIFICANCE In order for the invention of radio broadcasting to come to fruition, scientists first had to  discover radio waves that carry the signals. Scientists, such as Guglielmo Marconi, had to deduce how to send signals wirelessly. As well as scientists, the radio needed to have electrical  engineers and physicists, such as Lee De Forest, in order to create the actual device to be able to  receive and send radio waves. Lee De Forest invented a device called the audion which detected  sound waves. Later on in the development of radio broadcasting, psychologists were needed in  order for businesses to create better advertisements to send out to the general public. CONCLUSION The invention of radio broadcasting is the most significant invention in the last one  hundred years. This is because the radio created a revolutionary method of communication. The  radio also gave birth to electronics by leading scientists to create the television. Radio has  furthermore created a new way for information and entertainment to reach the general public and Thelen6 for these reasons, radio broadcasting is the most important invention in the last one hundred  years.
