     For several years, Americans have enjoyed teleshopping, watching TV and buying things by phone.    1   In a number of European countries, people can turn on their TVs and shop for clothes, jewelry,

food, toys, and many other things.

       2    For example, the biggest Swedish 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, and the

French spend about $20 million a year to buy things through those channels.

     In Germany, until last year teleshopping was only possible on one channel for 1 hour every day. Then

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

largest American teleshopping company and a 24hour teleshopping company. 

       3  

     Some people like teleshopping because it allows them to do their 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.    4    Many Europeans usually worry about the

quality of the things for sale on TV. Good quality is important to them, and they believe they cannot be

sure about the quality of the things on TV.

       5   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.

A. Now teleshopping is starting in Europe.

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

the American companies.

G. German teleshopping business is controlled by America.
