　　London has a magazine which you can receive on TV, because it is not printed on paper．

　　If you want to read this magazine, you have to get a decoder(译码)．Each page of it is numbered, so you only have to dial(拨)the number to choose what you want to read about．You can choose anything you want, from cooking to the latest news．

　　If you want to read the news, the first thing you have to do is to turn to the index(　　)page which has an easy-to-remember page number, 100．Then you choose what you want to read．The news is on pages 101 to 109, so when you push the numbers you can see the news written across your screen．Perhaps you want to go out in the afternoon, if so you can press 181, and you can see a brightly colored weather map on the screen．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 and the best thing about the service is that it is being updated(更新)all the time．Whole pages of the magazine can be replaced(取代)in minutes．

　　London already has three such services．One, transmitted(传送)by TV, is called ORSCLE．The other two, on BBC, are called CEEFAX and ORACLE because they let you see facts．Though CEEFAX and ORACLE have been in use for some time, they have not been publicized(公布，宣传)．BBC engineers don’t think that their idea will ever replace books and newspapers because they can be taken with a person everywhere．However, many people would agree that this is a breakthrough as great as the invention of printing, which could change not just our reading habits but our whole way of life．
