This is good, but it gets better. Because the messages are being routed between computers it is easy to duplicate them, ie send them to many recipients. This is often done by so called 'lists'. This is the way that group discussions can take place. If email is like a fast version of the postal service the Web is more like conventional publications.
People set up Web 'pages' which are, in effect publications.
Words, images, video and audio sequences can all be incorporated in Web pages. Whereas the email beats conventional mail in terms of speed, the Web beats conventional publishing in terms of cross referencing. A magazine may refer you to some original material in a book which you can then obtain and refer to. There are many more wonderful aspects to internet such as 'search agents' which you can set to roam the computers offering information and find just that information you have specified. But the email lists and Web pages are probably all most people need to know about.
