Zattoo is a fantastic free application available to various countries in Europe that allows the user to watch many of the free airing TV channels in the area without having to connect the computer to an arial or even be in an area where there is reception. It streams, via peer to peer technology, a live videofeed of a multitude of channels.

Unfortunatly it doesn't yet support the USA... but there's always the future! If you are one of the blog's european readers, be sure to check this one out.
