Recommended: Inventions from 1920 to 1930
Numerous inventions were developed in the 1920’s. Some are still used today, but others have become obsolete. Many modern-day household appliances, weapons, medications, and prepared food items had their basis in designs from this era. This technology contributed to economic prosperity and improved American lives in every conceivable way.
The first major invention was the commercial radio channel. In 1920, the Pittsburgh company KDKA broadcast that Warren G. Harding had won the presidential election against James M. Cox. This broadcast caused radios to increase in popularity. This improvement in radio was the only major development in sound technology; most people were working on visual transmissions at this time.
The first half-tone photograph sent in an electronic manner was transmitted by Western Union in 1921. The concept of a photograph being sent in this manner was conceived by Alexander Bain, a Scottish clockmaker, in 1843, but this was the first physical manifestation of his concept.
In the 1920s, multiple different people developed televisions. Unlike the electrical television we have today, these televisions were mechanical. The major model in America, invented by Philio Farnsworth, worked by utilizing radio transmissions and a spinning motor to display an image made of 60 horizontal lines. This model was perceived as a threat by the head of the Radio Corporation of America, and the resulting lawsuits eventually pushed its creator into committing suicide.
Another main version of the television was patented in 1929. This was Vladimir K. Zworykin’s kinescope, which was a cathode-ray tube. The storage principle it used is one of the main components of modern-day televisions.

...iple treatments to regain their own ability to breathe. In building the device, the inventors examined other methods of treatment for people who were unable to breathe. The doctors discovered that manually attempting to force the patient into breathing did not provide enough air, but all mechanical methods until this point forced too much air in too quickly, causing damage to other important organs. One of the goals for the design was to be able to put almost any person in it successfully.
Technology and human innovation led to some of the greatest economic prosperity that the United States had experienced to that point. New advancements, discoveries, and inventions improved American lives in ways that were never even considered possible before this point. In addition, these new developments inspired future inventors to improve upon the ideas of the predecessors.
The 1920's were a time where North America became modernized. Whether it was the music, the culture or the growth in technology, this time era is known to most people as the point where America advanced itself to become a world renowned country. An advancement that will be focused on is the Ford Model T. During this time owning a car was a symbol of wealth. Henry Ford, the creator of the Model T, made a system that revolutionized the automobile industry as we know it today. Henry Ford made it possible for people with an average income to own a motor vehicle by creating the assembly line and the theory of mass production. "The horse, which had been the chief means of land transportation for 3,500 years, had given way to the automobile, and the country's largest industry had been born." (Gordon)
The radio revolutionised the way families spent time together and receive information. The movie theaters had an impact on how people forgot about the depression and made life seem better. Many homes in the 1920s also just got access to electricity while many homes were still lit by candle light, but became more prominent as the time period continued. Labor saving appliances of the 1920s made the household chores easy to accomplish than it used to be. The 1920s was enriched by many technological achievements that helped changed the way americans communicated, managed their health, and partook in leisurely activities.
The technology in the 1920’s was the start of everything we have now. Many things were being made like helicopters, penicillin, radios, and refrigerators. This made people feel innovative and relaxed because they were letting robots/machines do their jobs for them making life easier.
In the 1920's, corporations started to take better care of their workers than they had in the past. Workers were paid higher wages and worked shorter hours. With more time and money on their hands, workers turned into consumers, which caused an increase in the production of consumer goods. One of the most popular consumer goods is the automobile. To keep up with the high demand, the automobile industry had to create a way to make a lot of cars in a short amount of time, at a low price.
Through out the 1920’s many inventions were created that altered human civilization. Transportation was successfully mastered. Radio communication was becoming more common and medicine was saving more and more lives every day.

Throughout the 1930s, the American people were financially struggling because of several nation wide crisis, like the Great Depression, for example. The Great Depression was a dramatic incline in unemployment and poverty, caused by the Stock Market crash of 1929 (History.com). American people during the Great Depression were not only losing all of their money, but they also were losing the ability to afford enough food to survive. Approximately seven million American citizens had starved to death before the end of the Great Depression (History.com). At its peak, the Great Depression had left about 25% of the American population unemployed (Great Depression). Although the Great Depression was extremely depriving of America's economy and people, it lead to many technological advances.
It all started with a guy named Philo Farnsworth in 1927,when the television was first invented. In a book called Television: Technology and Cultural Form by Raymond Williams, who was a Welch academic, novelist and critic, noted, “Television was invented as a result of scientific and technological research. It powers as a medium of news and entertainment was then so great that it altered all preceding media of news and entertainment.” Many speak and say the television has altered this world. Television was invented as a technological research and then became so popular amongst the people as entertainment. Beyond any doubt, this source of mass media has and is changing our lifestyles. Television is with us wherever we are, it eventually becomes a part of us. We watch TV as we eat breakfast, eat lunch, and eat dinner. Television wakes up with us and goes to sleep with us. It gives us pleasure, it is sometimes boring us, and most definitely challenges us.
In this paper, I will be explaining the life of John Logie Baird. He was the first man to invent the wonderful television in the mid-1990s. Although he wasn’t the very first to ticker with technology into making television, he just added onto the little knowledge from a big role model named Paul Nipkow. I’m going to educate you on his early life, how he invented the television, and many other facts.
Even with the ever-changing demands of technology around the world, the United States has continued to place emphasis on research and development; Americans have never ceased to make our everyday lives better with innovations and world-changing inventions. The endless number of American inventions, their complexity, as well as the dedication of intellectuals to improve the lives of others make innovation a good thing about America.
Technology has really changed in a massive amount from 1970 to 2016. The first mobile telephone call was 40 years ago on the day of April 3, 1973. In 1970 nobody had wondered or even thought that technology would come to be what it is today. There is something called “Moore’s Law” the definition of it is that it’s the doubling of internet speed every 18 months. At today’s rate, according to Ray Kurzweil, a human will experience up to 20,000 years of progress in their lifetime, rather than 100 years which was about the measurement in 1970. Kurzweil wrote this or said this in 2001 so i suspect the number is way greater now. Kurzweil also says this “Just think about how much things have changed in the past 10 years—wireless internet, smart phones, Facebook and Twitter—and then try to imagine how vastly different things will be in 2021, or even 2100.” In the year 2016 we have bluetooth and iphones
Over the years since the first television was invented in 1884 the television has changed an unbelievable amount from it being a very large made out of wood box with a small screen with black and white pictures, to it being a thin high quality product which is made from a variety of materials such as plastic, stainless steel and even wood.
The miracle of the television is credited to Philo Taylor Farnsworth, who invented the existing system of the television transmission and reception at his 202 Green Street Laboratory in San Francisco, California in 1927. (Philo Farnsworth, 2002: 1). Though, visionary inventors first imagined ideas of television?s potentials as the 19th century ended. George Carey of Boston first hinted transmitting every component of a picture over numerous circuits in 1875, but others like W.E. Sawyer introduced converting of images over a single wire or channel by quickly scrutinizing picture components in progressio...
Since it’s start television has grown in availability and reached the living rooms of many. Television’s expansion started off slow due to the Depression and World War II. By the end of World War II, TV was certain to grow as fast as the radio had twenty years prior (Jost 1139). Television has also developed better technology as it is now shown in color with digital picturing. This started towards the late 1930's, when new technology was being used to show baseball games and special events (Jost 1138).
To start off, John Logie Baird invented the mechanical television in 1926. The soul purpose of the mechanical television was to be able to see images at home from current events from around the world right in your very own home. But what Baird did not know was that in the future much controversy would come from what was viewed and played on the television set that he had created.
