(十九) Characteristics of Publicity
Publicity offers several benefits. There are not costs for message time or space. An ad in prime-time television may cost $250,000 to $5000,000 or more per minute, whereas a five-minute report on a network newscast would not cost anything. However, there are costs for news releases, a publicity department, and other items. As with advertising, publicity reaches a mass audience. Within a short time, new products or company policies are widely known.
Credibility about messages is high, because they are reported in independent media. A newspaper review of a movie has more believability than an ad in the same paper, because the reader associates independence with objectivity. Similarly, people are more likely to pay attention to news reports than to ads. For example, Women's Wear Daily has both fashion reports and advertisements. Readers spend time reading the stories, but they flip through the ads. Furthermore, there may be 10 commercials during a half-hour television program or hundreds of ads in a magazine. Feature stories are much fewer in number and stand out clearly.
Publicity also has some significant limitations. A firm has little control over messages, their timing, their placement, or their coverage by a given medium. It may issue detailed news releases and find only portions cited by the media, and media have the ability to be much more critical than a company would like.
For example, in 1982, Procter & Gamble faced a substantial publicity problem over the meaning of its 123-year-old company logo. A few ministers and other private citizens believed resulted in the firm receiving 15,000 phone calls about the rumor in June alone. To combat this negative publicity, the firm issued news releases featuring prominent clergy that refuted the rumors, threatened to sue those people spreading the stories, and had a spokesperson appear on Good Morning America. The media cooperated with the company and the false rumors were temporarily put to rest. However, in 1985, negative publicity became so disruptive that Procter & Gamble decided to remove the logo from its-products.
A firm may want publicity during certain periods, such as when a new product is introduced or new store opened, but the media may not cover the introduction or opening until after the time it would aid the firm. Similarly, media determine the placement of a story; it may follow a report on crime or sports. Finally, the media ascertain whether to cover a story at all and the amount of coverage to be devoted to it. A company-sponsored fobs program might go unreported or receive three-sentence coverage in a local newspaper.

(二十) Rockets in the Sky
If someone asked you, "What color is the sky?" I expect that you would answer, "Blue." I am afraid that you would be wrong. The sky has no color. When we see blue, we are looking at blue sunlight. The sunlight is shining on little bits of dust in the air.
We know that there is air all around the world. We could not breathe without air. Airplanes could not fly without air. They need air to lift their wings. Airplanes cannot fly very high because as they go higher the air gets thinner. If we go far enough away from the earth, we find there is no air.
What is the sky? The sky is space. In this space there is nothing except the sun, the moon and all the stars.
Scientists have always wanted to know more about the other worlds in the space. They have looked at them through telescopes and in this way they have found out a great deal.
The moon is about 384,000 kilometers away from the earth. An airplane cannot fly to the moon but there is a thing that can fly even when there is no air. This is rocket.
I am sure that you are asking, "How does a rocket fly?" if you want to know, get a balloon and then blow it up until it is quite big. Do not tie up the neck o f the balloon. Let go! The balloon will fly off through the air very quickly. The air inside the balloon tries to get out. It rushes out through neck of the balloon and this pushes the balloon through the air. It does not need wings like an airplane.
This is how a rocket works. It is not made of rubber like a balloon, of course. It is made of metal. The metal must not be heavy but it must be very strong. There is gas inside the rocket which is made very hot. When it rushes out of the end of the rocket, the rocket is pushed up into the air.
Rockets can fly fat out into space. Rockets with men inside them have already reached the moon. Several rockets, without men inside them, have been sent to other worlds much farther away. One day rockets may be able to go anywhere in the space.
