     For several years, Americans have enjoyed teleshopping-watching TV and buying things by phone. Now

teleshopping is starting in Europe. In a number of European countries, people can turn on their TVs and shop

for clothes, food, toys, and many other things.

     Teleshopping is becoming popular in Sweden (瑞典).The biggest Swedish company sells different kinds of

things on TV in fifteen European countries, and in one year it made $100 million. In France there are two

teleshopping channels (频道), and the French spend about $20 million a year buying things through those

channels.

      In Germany, until last year teleshopping was only possible on one channel for one hour every day. Then

the government allowed more teleshopping. Other channels can open for telebusiness. German businesses

are hoping this new teleshopping will help them sell more things.

     Some people like teleshopping because it allows them to do shopping without leaving their homes. With all

the problems of traffic in the cities, this is an important reason. But at the same time, other Europeans do not

like this new way of shopping. They call teleshopping "junk (劣质货) on the air". Many Europeans usually

worry about the quality (质量) of the things for sale on TV.

     The need for high quality means that European teleshopping companies will have to be different from the

American companies. They will have to be more careful about the quality of the things they sell. They will

also have to work harder to sell things that the buyers cannot touch or see in person.
