       For several years, Americans have enjoyed teleshopping-watching TV and buying thing by

phone. Now, teleshopping is starting in Europe. In a number of European countries, people can

turn on their TVs and shop for clothes, jewelry, food, toys and many other thing.

      Teleshopping is becoming popular in Sweden. For example, the biggest Swedish teleshopping

company sells different kinds of things on TV in 15 European countries, and in one year it made $

100 million. In France, there are two teleshopping channels (频道), and the French spend $ 20

million a year buying things through those channels.

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

the government allowed more teleshopping.  Other channels can now open for telebusiness,

including teleshoping, because it allows people to do their shopping without leaving their homes.

With all the problems of traffic in the cities, this is an important reason to allow more teleshopping.

But at the same time, other Europeans do not like this new way of shopping. They call teleshopping

" junk on the air". Many Europeans worry about the quality of the things for sale on TV. Good quality

is important to them, and they believe they can't be sure about the quality of the things they see on TV.

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

from 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 can't touch or see in person.
