My favorite show used to be "The Screen Savers" that was on a channel called "Tech TV". They got bought out and the new owners ruined the show and the entire network. Fortunately, most of the ones I liked best from that show have gone on to other web- based things.
The originator of the show has several podcasts that I listen to.
Two of them are working at pcmag.com and putting out a twice-weekly tech show that is download only at http://dl.tv
Another of them went on to create a very popular news site called http://digg.com
I really miss that show, but now I actually get more hours of entertainment from all the things they went off do to after the breakup.
