2)Paper The invention of paper was necessary once a form of written communication was invented. Paper was the surface that made written communication manageable. At first, clay tablets were used for written communications but they were bulky and difficult to transport. The Egyptians came up with a woven surface from the papyrus plant and painted hieroglyphics on this paper. The Greeks used a parchment from animal hides. But it was the Chinese who invented the standard writing surface of paper that is still used today. While the Chinese were using paper around 100 B.C., it was not used widely in Europe for another thousand years. The invention of paper allowed those who could read and write to attain wealth and social status. It also made tax collecting and record keeping easier. Another way that the invention of paper had a profound influence on society was that history and journals could be written for future generations to read. Finally, the laws of the land could be recorded and developed on paper thereby establishing a posted code of civil conduct. Paper can be made from wood fiber, hemp, cotton, linen and rice

3) Print The invention of printing satisfied the huge demand for books. After the invention of paper, there was a tremendous demand for books to be written. But all books had to be written by hand and this was tremendously time consuming and expensive. If you wanted to write a book you had to hire a scribe to write it and it was costly. The Chinese developed a block printing system in 868 and then a kind of movable type made of clay and then wood. The Koreans even had a movable type in the 15th century. But it was in Germany where Johann Gutenberg developed the printing press that utilized movable type and allowed the Bible to be printed about 1453. This printing method spread throughout the continent of Europe. Suddenly books were being printed, although the rich were the only people who could afford them. The newspaper was officially created as the primary source of news for the masses.

4) The Telegraph It is impossible for those of us today to imagine life without our cell phones, but before cell phones were invented there was another huge milestone in the invention of the telegraph. The telegraph was the fastest form of communication at that time and seen as remarkable. It could travel with a message at the speed of light. Samuel Morse was one developer of the telegraph and his “Morse code” of dots and dashes is still used today. The telegraph was called “the great annihilator of time and space” in that it changed society itself through transportation in the railroads, the way war was conducted, the speed of communication between buyers and sellers and trans-Atlantic communication. Most of all, the telegraph was pivotal in the formation of news services and agencies.

5) Photography The invention of the camera was first evident in the photographs taken during the Civil War. Suddenly war was a horror in the visual sense that was never understood even in the most graphic written descriptions. Photojournalism where “a picture says a thousand words” became popular as a picture could be internalized faster than the written words. For the first time historical information could now be journalized in pictures and images.

6) Cinema The technology of the camera led to moving pictures and the video capabilities that we have today. Movie theaters and “nickelodeons” became big hits. By 1910, there were more than 10,000 such movie houses in America. Soon filmmakers began to see the power in producing films and the potential for a huge business.

Описание слайда:

8) The Television Once again the technological advancements of war paved the way for television in the 1950’s. The television in the 1950’s and 1960’s was the most wanted appliance. About 10 million Americans had a television set in the 1950’s. It soon became a huge consumer of time. People watched their news each evening as well as their various television shows. The entertainment industry now branched off from films into television. Television became a massive form of communication and generated social changes. We watched the Vietnam War and the assassination of John F. Kennedy on our televisions.

9) The Computer and Internet The digital revolution allowed computers to instantly relay information to all parts of the world. In the blink of an eye, through computers and the Internet mass communications was changed forever by bringing the people of the world together. Newspapers and magazines are now online, as well as on paper. Music-sharing sites are online for distribution both legally and illegally. Businesses can be anywhere whether in a downtown office or in a bedroom. You can buy and sell anything online. You can pay your bills and do your banking online. You can meet people in chat areas and have online relationships. Everyone has a website and politics has invaded the Internet as well. In 2004 in the United States, 1 dollar of every eight dollars was spent online. Emailing is now more popular than “snail mail.” Al Gore, the Internet’s creator?

10) Wireless Technology Wireless portable media has overtaken our society in the presence of wireless laptops, cell phones and PDAs. Everywhere we look in public places we see the huge impact of our wireless connections. It is difficult to remember life without a cell phone or a wireless connection. I often wish I had stock in a cell phone company as I scan my own monthly bill. But with the speed of technology everything we buy today will only be more advanced tomorrow. Technology quickly becomes obsolete as something new is introduced.
