Mike Butcher at Techcrunch UK has a[ great round up of UK efforts at webcasting:](http://uk.techcrunch.com/2008/03/11/home-grown-video-shows-on-tech-are-almost-there-but-not-quite/)

Without access to a potential audience of millions in the US and the subsequent advertising revenues, video webcasts on this side of the pond have been patchy affairs. And especially in the realm of tech business news the content tends to be thin on the ground.

A great round up with some great examples.  Well worth a visit.
