I like podcasts. They're free, and I get through a lot of background media while I'm otherwise engaged in walking or drawing, or waiting for things to happen. I chew through a lot of tech news this way, absorbing it by osmosis...
This Week in Technology (TWiT), both as a producer and a show, are one of the best, supplying good quality professional audio or video, as well as professional pundits, including John C. Dvorak, Jeff Jarvis and Paul Thurrot (Who wrote the book on Windows). TWiT is hosted by the genial, velvet voiced, Léo Laporte on most of the large number of programmes, though not all. TWiT also produces themed episodes covering most topics.
For people who say "Fuck!" and talk about their dicks, Smodcast is worth a listen. Run by Kevin Smith, writer, director and fat guy (Also known as Silent Bob, the best misnomer in show biz, because this fucker will not shut up), Smodcasts offerings run the geek gamut of Hollywood gossip, movie making (Kevin acted in, wrote and directed a lot of films), comics (Kevin owns a comic book store, the staff of which had their own TV show), and Jason Mewes.
Jason, actor, ex junkie, fucked by life before birth, possible village idiot, deserves a category all of his own, because he's such a strange affable guy, and so much fun to hear bantering with Kevin on their shared podcast, "Jay and Silent Bob get old" - A comedy that's recorded on stage and popular enough to be on tour.
Finally, in my picks, Kevin and Ursula Eat Cheap - An amateur podcast by fandom darling Ursula Vernon and Man Friday, Kevin. Every week they taste test and rate cheap food so you can listen to them suffer and get drunk while MST3King the food.
All KUEC episodes are recorded in front of a live beagle to ensure quality.
