I'll throw a shout out for Brewing Network. If you are easily offended by locker room humor disregard. But if you can tolerate that, there is a ton of good info as well as entertainment. Caviat, no matter where you look you will find info and techniques that are questionable or outdated. For example the latest issue of Zymurgy is still suggesting olive oil in yeast starters. Awesome magazine, but you need to learn what is good info and what isnt. The BN is no exception. IE its not perfect, and shouldn't be taken as a fountain of irrefutable truth.
Having said that, there are shows on technique and technology (brew strong). Shows on all of the classic styles (brewing with style). Shows on sour beer, and The Session which is the flagship show. Also, Dr Homebrew where you send in a beer and two master judges give you feedback on the air. I submitted a couple lately and got great feedback, plus a couple 2L Erlenmyer flasks, some Starsan and PBW, and two full cases worth of reusable custom made beer bottle labels. Pretty awesome deal.
A few people hate the BN, but in my opinion they are awesome. Worth a listen.
