There's also an international newsgroup about community TV, alt.tv.public-access which many community TV centres in the US have been reading and writing to. Also worth checking out for the technical side is the rec.video.production newsgroup. Also from Sweden is a more general colection of community TV groups. PBS in the US now have some Web pages. There are other US-based community TV and radio groups which I should probably get links onto this page for, as well.
Paper tiger looks interesting, it's a show out of New York that's pretty critical of the media.
