The Internet

The internet has changed the world since 1960, when it was invented. Before this, when you wanted to search information you has to use books. But now you can do more than this, with the Internet you can search information, listening to music, to read some books...
Books, in the other hand, are old-fashioned. Nowadays nobody uses books to search information.
The Internet, however, is dangerous because you can tala with everybody bus sometimes the people who you are talking to, aren't who they seemed to be. You must to be very careful when you are surfing on the Internet.
All in all, I think that the Internet is much more useful than books.
