Top Five Best Inventions of The 20th Century
Have you ever wondered how something was invented? Have you ever wondered why they were invented? Well, I have and this is the result of that wondering.
During the twentieth century, inventions were needed to keep up with the times and be the best country we can be. Most of these inventions were used to keep up with the war, such as the radio and the airplane.
Other inventions, such as the car and television, were necessary to keep up with the automotive and technological world. Without all of these wonderful inventions, where we be today? Well, for starters, there would be no space travel, or for that matter, no travel at all.
The Radio:
Guliemo Marconi first created the radio. He invented it for navigational purposes. Marconi tried to mass-produce his idea but no bankers would lend him money because they thought there would be no money in it. After searching high and low for investors Marconi gave up. Later on in his life the U.S. government bought out his idea for navel and army uses. The government realized that they can do a lot more with it than use it as a navigational tool: They figured out that they can send voices and sounds through it and used it as a two-way communication device, then later found out that it can be used as more than a two-way. As this device was progressing, it became TV station waves (Later stated). The radio played a big part in world war I and II, not only on the battle field but on the home-front as well: People bought radios to use a listening devices to hear the news and there favorite broadcasting programs such as The Shadow, War of the Worlds, Suspense and Amos& Andy.
The Television:

This computer was not the biggest made but for its work it was the largest and heaviest. The Mark one weighed over 5 tons and it was 50 feet long by 8 feet high. "Sounds like a room full of ladies knitting," said Howard. Aiken thought that the idea of a computing device "computer" would not become useful to every day people, just experts and scientists. If only he could see us now.

People were able to directly communicate with others hundreds of miles away by way of telegraph and later, the telephone. In 1920 the first radio was invented, which in a way, united the country. Soon after the television was invented and American society and culture became one and the same in every corner of the country.

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...
Many of the inventions during the 1920s modernized America. Inventions of the 1920s include the American Hammond Organ, adhesive bandages, car radios, loudspeakers, electric shavers, and traffic signals. Household items like electric irons, toasters, refrigerators, air conditioners, radio, television, and vacuum cleaners made daily life very different from previous generations. The radio was in almost every home and provided listeners with sports, concerts, and news. Radio quickly became a national obsession. For those that could not afford a radio, the radio in public places became a gathering place and allowed people to keep up with issues and share ideas and opinions. The first movie with sound was introduced and started the movie industry. As automobiles became more affordable, movie theatres became more popular. The 1920s not only introduced sound to movies, but also Technicolor. Movies soon became America’s favorite form of entertainment. The aviation industry was also stimulated with Charles A. Lindbergh’s first flight across the Atlantic Oce...
Gunpowder, the vaccine, blood transfusion, the telescope, surgery, the submarine, the barometer, the submarine, and the microscope are all great inventions that helped change the way people live today. They are some of many scientific inventions that changed the way of life for people.

Now a lot of these inventions have helped shaped America. Such as the train and car, which have changed transportation and trade for good. Then there are the electrical inventions, such as the light bulb and the alkaline storage battery. Changing the way people live at home. Its almost impossible to live with out those two inventions, especially since love their television and computers.
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...
