Introduction The twentieth century was one of the most remarkable centuries in history referring to the technology advances and scientific discoveries that it had. They are still continuing today. The advances that I believe shape our world today that occurred in the twentieth century are internet, radio and antibiotics. Like I mentioned before, there were so many advances; even inventions. Yet I feel that these three are extremely important.
Radio
The impact that the radio had on the twentieth century is not appreciated. Not only did the radio make it possible for a person to be heard thousands miles away without any use of wire. During the end of World War 2 and into the 1950’s the radio was the center of family life. The radio was the source of entertainment and news. The only time the radio lost its fame was when the television was invented, and when families were replacing the radio with a television. Sadly today the radio is mainly used in vehicles. The radio is a great tool for drivers to keep from falling asleep behind the wheel or some radios in new models of cars; they can communicate through their radio speakers.
The advances that the radio had during the twentieth century been very important and life changing. When the radio was first invented it was a great success and it did the job it entailed. During the 20th Century the radio made some very important advances, they are advances ranging from transmute radio signals to amplifier levels, and FM radio to HD radio. All these advances made the radio what it is today. Transmatic radio signals are when a wireless receiver can transmit sound from over 2000 miles; this is a new way to send Morse code. FM Radio and HD radio advances came in the late twentieth century yet they were just as important; the FM radio came to solve the static problem that the AM radio was having. Rather than increasing the strength of the radio waves, Armstrong changed the frequency on which the waves were transmitted. HD radio came to bring a clearer sound and by doing so the Federal Communications commission sets a testing schedule for all radios to have HD, never just an option.
Antibiotics
It is bazaar to imagine a world before the development of antibiotics. Penicillin was invented just 86 years ago. During the twentieth century antibiotics had some great achievements. Antibiotics serve an important role of keeping the public healthy. During the 20th century antibiotics advanced mainly because the invention of Penicillin. Antibacterials are designed to test bacterial infections. Billions of bacteria live under our skin; antibiotics are preventing the spread of the bacteria by killing it. 90% of children with bacterial meningitis died before antibiotics. The children that lived had severe lasting disabilities. The invention of Penicillin decreased the number of deaths due to bacteria illness.
Internet
In the twentieth century the internet was not what it is today. The internet is connecting a computer to any other computer in the world via dedicated routers and servers to get us information we need. When more than two computers are connected over the internet they can send and receive information, graphics, games and so much more. The internet is not owned by anyone, there are several organizations around the world that collaborate in the development and functioning but it is not owned by one person. The high speed fiber optic cables are owned by the telephone companies in the respected country. When the internet first began in 1960, it was for collaboration in military research for business and government laboratories; today everyone has access to it and can search anything they desire.
Conclusion
To conclude the twentieth century was extremely important due to technology advances. Today in the twenty first century, we would not be where we are without the advances we had a century ago. We are living in a world that is ever changing and we need to run with it and accept it.

Scientists and inventors are always on the lookout to invent something to make the average person’s daily life easier. The 20th century brought many technological advances in the world from the television to the air conditioner. Many of the technologies so fundamental to everyday life came from advancement during this time. The author of the paper will discuss three technological developments in the 20th century including: the airplane, the automobile, and the computer. The Airplane For centuries humans wanted to invent a device that would allow them to fly like birds. Kites, gliders, and air balloons were many of man’s creations to attempt to derive the privilege of flying. Two men, Wilbur Wright and Orville Wright, were the first to find some success in inventing a device that enabled flying. On December 17, 1903, the Wright brothers flew there invention for the first time. However, this was only a small start because their aircraft did not fly very high and it only stayed in the air for about a minute. Although this was a small triumph in the goal of flight it marked the beginning of the technological advances that produced the modern airplane. When the Wright brothers invented their aircraft they received immediate recognition and other inventors and aviators worked hard at inventing a better aircraft. In 1909, Louis Bleriot, a French...

Effects of Mass Media

...evolution of mass media during the 20th century? The most important development of the 20th century concerning the evolution of mass media is technology. In the beginning everyone was finding their information from the newspaper and the telegraph. That information was days old at best for some places in the United States. Then the radio was invented and information was able to be put out to the masses very fast. As technology progressed, the way people received their news went from reading a paper to listening on the radio and eventually in the 60’s to a television set so you no longer had to be anywhere but your living room couch to find out what was going on the world. Shortly after, the computer and internet was invented which led to the biggest leap in my opinion in technology of the century. With a computer everyone that had access to the internet could essentially put whatever they wanted out to the mass media instead of just being big time news stations. News became just a click away from one end of the earth to the other. A very large percentage of the United States probably can’t go 10 minutes without having the urge to look at their cell phone or update their status on a social media website. It’s as if it makes you believe that social media was developed for the sole purpose of advertising to the public. From paper to radio waves, to signals being broadcasted from space the greatest development of the 20th century would have to belong to technology. How did each......

Military Power

...remains as the driving force behind the machine known as the United States. America’s military force has always been a threat, and began to emerge to the forefront during the 20th century; it wasn’t until the turn of the 21st century that its true power was exerted. This paper will discuss: America’s rise to military “glory” during the 20th century, its present state, and what must be done in order to preserve it status as a world power in the future. Rise to Military Dominance At the turn of the 21st century, the United States military was at a standstill in terms of military action; especially when compared to the 20th century. The 20th Century was the “bloodiest, costliest century of warfare in human history”; with major conflicts happening seemingly every day. World War I and II, a large number of major revolutions; along with significant social, political, and economic upheavals made the period from 1901 to 2000 of great importance in a historical and military sense. It can be said that the 20th century paved the way for the outlook of the 21st century American military. The fight was expanded from the ground and sea to the air with the invention of Aircraft. Nuclear weapons, the “crown jewel” of modern military weaponry, were first introduced to the world during the 20th century. The 20th century also saw the...

...http://www.artinthepicture.com/styles/Futurism/ Futurism was a 20th century art movement. The Futurists loved speed, noise, machines, pollution, and cities; they embraced the exciting new world that was then upon them rather than hypocritically enjoying the modern world's comforts while loudly denouncing the forces that made them possible. Fearing and attacking technology has become almost second nature to many people today; the Futurist manifestos show us an alternative philosophy. The Futurists explored every medium of art, including painting, sculpture, poetry, theatre, music, architecture and even gastronomy. The Italian poet Filippo Tommaso Marinetti was the first among them to produce a manifesto of their artistic philosophy in his Manifesto of Futurism (1909), first released in Milan and published in the French paper Le Figaro (February 20). Marinetti summed up the major principles of the Futurists, including a passionate loathing of ideas from the past, especially political and artistic traditions. He and others also espoused a love of speed, technology and violence. The car, the plane, the industrial town were all legendary for the Futurists, because they represented the technological triumph of man over nature. http://www.huntfor.com/arthistory/C20th/futurism.htm Futurism came into being with the appearance of a manifesto published by the poet Filippo Marinetti on the front page of the February 20, 1909, issue of Le Figaro.

Imagined Communities

...Katie Kavanagh 27 July 2014 The Information Age: Assignment #2 America is constantly developing as a nation along with the smaller communities that have formed within it, and information technologies have proven over time to create communities, both real and imagined. Although there are many different kinds of technology that have helped developed the nation and the world, one tool especially useful in disseminating this community-building information is the newspaper. Benedict Anderson, Professor Emeritus of International Studies, Government and Asian Studies at Cornell University first created the term “imagined community”. Originally, the phrase was mostly used when referring to nationalism, but now it can be used to describe any group of people who share a common passion or interest. There are several different types of information that newspapers distribute; therefore, there are many kinds of imagined communities that they have created in the past and have the potential to construct in the future. By definition according to Anderson, a nation is “an imagined political community”—a widespread consciousness shared by its members who may never come into contact with one another. Consequently, the first way newspapers built an imagined community was by sparking the emergence of a national identity amongst American citizens. Alexander Ziegler conducts a study on the involvement of newspapers in the development of an American national identity in which he states:...

People Magazine

...people’s lives. Fame comes in many different forms in our culture today from professional athletes to actors to Kardashians, and people in today’s culture try to escape their own lives by reading about the lifestyles of these people. The notion of fame was not the same around the late 19th and early 20th century. There were large names such as Andrew Carnegie or JP Morgan, but working and middle class people were not obsessed over how these wealthy people were living. The closest thing to a magazine like People that existed was the notion of a painted woman. Painted woman stories were in the papers that covered sensational murders of women who were often incredibly beautiful and morally virtuous but for some reason strayed off course and paid the ultimate punishment for it. People around the turn of the 20th century were fascinated with these people, but the fascination was not an envy to be like them. There was not a fixation on becoming famous and well-known back then. American culture in the late 19th and early 20th centuries was undergoing serious change. The industrial revolution led to significant economic growth and concentration of wealth during the turn of the century, and with it came a complete change in cultural norms. Class formation started to become defining with the emergence of the middle class during the latter half of the 1800’s, and it led to the creation of new leisure activities, different social codes, and a new group of consumers. New industries......

However, there are some people would prefer to have mass media than none at all. In this paper I will analyze the way mass media has changed over the generations and how it has transformed. Secondly, you will learn about how each development influenced the world. I will discuss media convergence and how it done and what my personal thoughts and opinions on this process is. In the very beginning of the century, America relied solely on newspapers and articles. The evolution of mass media has increased over the years basically by how technology has transformed. Before internet no one had the luxury of downloading an app for weather or news media. It started with a basic paper delivery. No one buys the newspaper anymore because of how far technology has come. Another major development was the radio. Radio could provide war information much faster than newspapers, and people desired to hear current events of war situations, and the situations of family overseas. Ten years later television came to dominate the media industry (“Evolution of Mass Media in the 20th Century, 2015). By now, technology started developing more and more and soon people started getting televisions and figuring out how black and white TV was really about. Then started color TV, and that created a huge uproar with media and news. It was new, it was......
