I think the whole thing went down the drain when G4 bought out TechTV. Let me make this clear: I hate what G4 was and I certainly hate what it is. TechTV was awesome. It was fantastic. It was the coolest channel on television. Then G4 came.
I know that a lot of people like the old G4 shows like the old version of Cheat!, Electric Playground, Cinematech, Judgement Day, and so forth, but I hated those shows. I didn't like the hosts, like the punch-pulling Victor Lucas, the tries-too-damn-hard Corey Rouse, and Tommy Tallarico (who gives Ninja Gaiden a 7.5 out of 10?!), though he redeemed himself somewhat by working on The Bard's Tale.
Nearly everything on TechTV was at least good and at most awesome. Fresh Gear, Screen Savers, Gamespot TV/Extended Play/X-Play (back when Adam and the show still had integrity), Unscrewed with Martin Sargent (how I miss that show), and Eye Drops had some nifty stuff now and again. TechTV was the real tech geek/gamer channel.
G4 was a bunch gaming shows that I found to suck, but at least they were still gaming shows. Now, it is to games what Margaret Cho is to humor: it is its antithesis.
