[Edited to add] I don't understand why the link does work.. it should take you to http://www.tv-tube.net/ so try typing it in directly, rather than clicking on the link, if you're interested.

Zattoo

Watch online TV. Zattoo enables you to watch real TV on your PC and it's absolutely free! It's the football game as you chat, the news as you email, and your favorite soap as you pay your bills. Zattoo is also TV when you don't have a TV - it's the channels you want, when you want, where you want. I'm assured that it's all perfectly legal, but it does require a download in order to make it work, which is why I haven't tried it myself. If you do, leave a comment!
