Can we watch 3D (three dimensional) TV programs without the glasses? With the development of the technology, we can make it soon.

Lately, there has been much progress of this video system by some scientists at the University of Arizona. It is said that the researchers at the University of Arizona have created the world’s first 3D video display that uses an onboard memory and can also be updated. So far the 3D displays produced in the labs can be erased and rewritten in only a few minutes. For a 3D television to be created however, the display would need to be overwritten several times in a second, something to be achieved within the next decade.

This ability to erase and rewrite a 3D projected(投射)image is considered as a huge breakthrough in this field. Indeed it gives lots of hope that even the remaining bits can be achieved. The main challenge now is to come up with methods of continuously erasing and rewriting the image. According to most researchers, an eventual 3D television will have a flat screen construction, which is similar to the modern day displays with flat panels. However, for the case of the 3D television, the display would most likely need to be placed on the floor, right in the middle of the viewing room as is presently done with the coffee table. The image would then be projected above the display screen of the “coffee table”, where it would be viewable in 360 degrees.

While it is quite easy to demonstrate the great potential of the 3D TV in a laboratory setting, it is entirely a different thing to produce in mass. Furthermore, in order to watch a 3D TV, there would be required 3D TV programs. This is no small task as creating even a very cheap 30-minute comedy in the 3D format would need a vast amount of expensive equipment as well as technical knowledge.

It would therefore call for very serious duty by the television networks to adapt to the 3D. But because the technology is there, sooner or later, be put to good use. Even though 3D TVs may not be a reality within the next decade or so, it will eventually get there.

No one knows for sure when advertising first started. It is possible that it grew out of the discovery that some people did certain kinds of work better than others did them. That led to the concept of specialization, which means that people would specialize, or focus, on doing one specific job.

Let’s take a man we'll call Mr. Fielder, for example. He did everything connected with fanning. He planted seeds, tended the fields» and harvested and sold his crops. At the same lime, he did many other jobs on the farm. However, he didn't make the bricks for his house, cut his trees into boards, make the plows (犁) , or any of the other hundreds of things a farm needs. Instead, he got them from people who specialized in doing each of those things.

Suppose there was another man we shall call Mr. Plowright. Using what he knew about fanning and working with iron, Mr. Plowright invented a plow that made fanning easier. Mr. Plowright did not really like fanning himself and wanted to specialize in making really good plows. Perhaps, he thought, other farmers will trade what they grow far one of my plows.

How did Mr. Plowright let people know what he was doing? Why, he advertised, of course. First he opened a shop and then he put up a sign outside the shop to attract customers. That sign may have been no more than a plow carved into a piece of wood and a simple arrow pointing to the $hop door. It was probably all the information people needed to find Mr, Plowright and his really good plows.

Many historians believe that the first outdoor signs were used about five thousand yean; ago. Even before most people could read, they understood such signs. Shopkeeper« would carve into stone, clay, or wood symbols for the product they had for sale.

A medium, in advertising talk, is the way you communicate your message. You might say that the first medium used in advertising was signs with symbols. The second medium was audio, or sound, although that term is not used exactly in the way we use it today. Originally, just the human voice and maybe some kind of simple instrument, such as a bell, were used to get people's attention.

A crier, in the historical sense, is not someone who weeps easily. It is someone, probably a man, with a voice loud enough to be heard over the other noises of a city. In ancient Egypt, shopkeepers might hire such b person to spread the news about their products. Often this earliest form of advertising involved a newly arrived ship loaded with goods. Perhaps the crier described the goods, explained where they came from, and praised their quality. His job was, in other words, not too different from a TV or radio commercial in today's world.
