Many inventions have impacted the world throughout history but in my opinion one of the most impactful one’s was the invention of the radio . This invention provided society with many things which include entertainment, communication, and easier access to information. Radio is still a central part of the society today but just like any other invention radio has an interesting history of how it progressed through time.
Every invention ever known to man had pioneers or people who contributed to the creation of the product. Radio had many pioneers that allowed for its creation and their names are Heinrich Hertz, Nikola Tesla, Ernst Alexander, Edwin Armstrong, Guglielmo Marconi, Lee DeForest, Frank Conrad, Reginald Fessenden, and Edward Armstrong. It all started with a German physicist named Heinrich Hertz who in 1884 proved that you could transmit and receive electric waves wirelessly. Hertz thought that the work he had done had no use whatsoever but little did he know that what he done is considered the fundamental building block of radio, and that is the reason why every frequency measurement is named after him (Short). In that same year a Serbian-American inventor named Nikola Tesla came to the U.S and sold patents to his inventions to a man named George Westinghouse. After that Tesla established his own lab which is where he built the tesla coil , an induction coil that is still used in radio today (Short). The next progression of radio focused on more than just the transmission of waves, the new focus was transmission of speech. The first to begin to add speech into the radio mix was Ernst Alexander, a Sweden born inventor who developed the first alternator to make speech transmission possible (Short). This was so new to the s...

Wireless begins with a brief discussion of the 1995 centennial of the invention of radio by Marconi and a rebuttal by the British historians who oppose this claim. Using underused or previously overlooked or perhaps ignored resources the author disproves the claims against the originality and ingenuity of Marconi's 1897 patent on wireless telegraphy. While credit is given to several British scientists and engineers and their scientific discoveries and inventions, it was Marconi, a practitioner, who made the first significant breakthrough in practical wireless telegraphy when he "connected one end of the plate of the receiver, and one end of the transmitter, to the earth" (p. 20). Marconi transformed these scientific effects into wireless technologies and then exploited them for commercial purposes. The focus of British scientists and engineers on optical analogies, scientific experimentation and demonstration, and the fear of British national interests becoming monopolized (particularly by a foreigner) are the primary reasons for the dispute surrounding Marconi's patent. (By 1897 it was clear how wireless telegraphy would impact military interests.) The author shows in great detail how British scientists and engineers, namely physicist Oliver Lodge, J. J. Thomson, Minchin, Rollo Appleyard, and Campbell Swinton, deliberately constructed false scientific and social claims to discredit the originality of Marconi's patent.
Radio waves were first discovered in 1887, but radio itself was initially invented by Italian Guglielmo Marconi in 1895 (1). His biggest mentioned success was in 1901, when he managed to broadcast the letter “S” across the Atlantic Ocean (1). However, he focused primarily on point-to-point transmissions, not large scale broadcasts from one point (F). As such, three American inventors - Lee De Forest, Edwin Howard Armstrong, and David Sarnoff - took credit for making radio as it is today a success (F). De Forest was born and raised in Alabama and he thought of everything in terms of patents and eventually held more than 300, but many claimed that he simply stole the inventions of others (2). In 1900, he patented a device to enhance weak signals and in 1902, he formed the De Forest Wireless Telegraph Company (1). In the same year. Reginald Fessenden, a Canadian, invented the “electrolytic detector”, which later became the spade detector that brought De Forest so much fame (F). In 1904, John Fleming invented the oscillation valve, which later became De Forest’s audion, and De Forest won the gold medal at the St. Louis World’s Fair for his “spade detector” (F). De Forest gained quite a bit of fame by broadcasting music live from the Eiffel Tower and from the Metropolitan Opera; however, many believed that this was a scam and that he had actually had the device broadcasting the signal only a few blocks away (F). In 1906, he envisioned bringing music and voices to all American households, but as it turns out Canadian inventor Fessenden had already broadcasted a Christmas greeting and music to the crew of a ship off the coast of Canada on Christmas Eve a year earlier (F). In 1912, Armstrong became prominent by inventing regeneration, wh...
The 1920's brought many advancements in technology which allowed Americans to entertain themselves at home; the radio was one of them. The radio was actually developed before the 1920's; however, it was banned during World War I and allowed to reappear after the Prohibition ended in 1919 (Events 72). After the Prohibition ended, and radio broadcasting was being brought back to life, many people started up their first stations, like Frank Conrad (Events 72). Frank Conrad's first broadcast consisted of the Presidential Election results (Events 72). As Conrad was one of the first people to broadcast, KDKA was one of the first radio stations to appear in the Unite...
The radio has had a huge impact on bringing information to the public about war and other government issues. Advertising and broadcasting on the airwaves was a major step in bringing war propaganda to a level where people could be easily touched nationally. Broadcasting around the clock was being offered everywhere. Before there was television people relied on the radio as a way to be entertained, the means of finding out what was going on in the world, and much more. During the World War II time period, 90 percent of American families owned a radio, and it was a part of daily life. So it was an obvious means of spreading war propaganda. During this time period, propaganda was spread throughout the radio by means of news programs, public affairs broadcasts, as well as through Hollywood and the mainstream. The average person had not even graduated high school at the time, and the average reading level of the American was somewhat low. The radio made it possible for stories and news to be delivered to everyone in plain simple English. The radio served as a medium that provided a sense of national community. Although it took time, the radio eventually rallied people together to back up the American war effort.
Before 1923 the only means of reaching a immense audience was through newspapers or word-of-mouth. With the new technology of radio broadcasting in 1923, it was possible to reach the vast majority of the United States’ population. On July 1, 1923 AT&T established the first permanent radio network, WEAF NY and WMAF Mass, that linked broadcasting stations (White). The first radio station to air was 3AR and it started transmitting music, news, and race results. In December of 1923 President Calvin Coolidge made the first presidential address on radio.
Wireless communication across the country was something no one ever imagined. The creating of the commercial radio in 1920, created a feeling of belonging to many citizens of the United States. Starting off as a hobby for amateurs, radio quickly expanded. With the creation of NBC, and emerging radio stars like Ernie Hare and Billy Jones radio, families tuned in on a daily basis. Music was brought to lower income families who couldn’t afford to buy a piano. As well as streaming music, radio provided advertising outlets. Promotions regarding cigarettes, automobiles, and soap

Usually, when people think about the inventor and founder radio, people tend to say it was Guillermo Marconi. However, after watching this documentary, I believe the inventor and founder of radio has to be the combination of the three men profiled in this documentary; Lee De Forest, Edward Howard Armstrong, and David Sarnoff. Lee De Forest is also sometimes considered the Father of Radio, and even the Grandfather of Television, however, there was always a lot of controversy over his work. Under multiple circumstances, his inventions and discoverers were previously discovered by other inventors earlier in time, leading to multiple lawsuits. Even though there was a lot of controversy over his ideas, he did however come up with one of the
After the First World War, many people were looking forward to good times. The 1920’s presented people with this time of fast-paced fun and adventure. Entertainment was the foremost part of everyday life during the 1920’s. Radio introduced a whole new practice of entertainment to people’s everyday lives. Likewise, through the utilization of the radio, people were able to experience a new medium to entertain themselves. Furthermore, the radio changed the face of society’s culture through its widespread use. In addition, radios provided people with a new, effective and efficient means of communication. Radio was a fundamental aspect in people’s lives during the 1920’s as it provided many people with news and entertainment in their day-to-day lives.
For centuries, governments have tried to regulate information thought to be inappropriate or offensive. Today’s technology has given the government an excuse to interfere with free speech. By claiming that radio frequencies are a limited resource, the government tells broadcasters what to say and what not to say. The FCC (Federal Communications Commission) carefully monitors news, public, and local programming for what they consider obscenity (Hyland).

By the time the 20th century arrived, vacuum tubes were invented that could transmit weak electrical signals which led to the formation of electromagnetic waves that led to the invention of the radio broadcast system (750). These vacuum tubes were discovered to be able to transmit currents through solid material, which led to the creation of transistors in the 1960’s (750).
Many inventions revolutionized society and one example is the telephone, which was introduced to society in 1876. The inventor, Alexander Graham Bell developed this idea and the telephone made him famous because communication would never be the same after the development of the telephone. The telephone made an incredible impact on society. The impact could be seen through the quickness of communication, business, easier communication in wars, and some negative effects too.

Radio broadcasting was introduced to the public in the early 1920s (Potter 226). There was only one type of broadcast protocol in the 1920’s and 30’s being AM radio(The Early Years). In 1921 there were only five AM radio stations, and only about 1% of all households in this country had a receiver (Potter 226). A receiver was basically another name for a radio because at this time radios were very expensive and there were not enough radio stations to make the system work. However, in 1923 there were over 500 stations to pop up which in turn led to increased sales of receivers to the general public (Potter 226). With the popping up of more radio stations the more receivers were being bought which meant that many people in the public were tuning into these various radio stations for information and entertainment. Radio was on the rise and it seemed that there was nothing slowing it down.
