     London has a new magazine . But it is not printed on paper . Everyone who has a television can receive
  it because it in on TV.
     If you want to read the magazine, you have to have a decoder (解码器) . Each page of it  is numbered,
 so you only have to dial the number to choose which subject you want to read about . There is a wide
 choice-everything is included from cooking to the latest sports news .
     If you want to read the news , the first thing you have to do is to turn to the index (索引) page which
 has an easy-to-temember page number, 100 for example. The news is on pages 101 to 109 so you push
  out the numbers and the news appears written across your screen .Perhaps you want to go out in the
 afternoon , so you press 181, and a brightly colored weather map appears on the screen. But the weather
  is terrible so you decide to go shopping and dial 162 for a list of the week's best bargains . But should
 you drive or take the train? To answer that question you only have to press 189 for the traffic report . It is
  very simple to use . But probably the best thing about the service is that it is being updated all the time .
 Journalists type new material directly onto the screen and whole pages of the magazine can be replaced in
  minutes .
