Shockwave is a new technology created by Macromedia, which allows us to broadcast multimedia files on the Net.
In order to view and listen to these files, you need to download the Shockwave plug-in to your hard disc. Then, install it in your browser. In most cases the instalation is done automaticaly when you download the plug-in.
To get the plug-in (for free) you can access Macromedia's website http://www.macromedia.com/shockwave/download
