The first thing he needs to do is fix everything about the channel, which is among the bottom five in the Nielsen cable ratings. Outside of the 90 minutes of original studio programming every weeknight, Ninja Warrior and Bomb Patrol: Afghanistan, it is a complete mess of a network that still thinks it's 2005, Maxim is a relevant men's title and that should be their programming attitude.
The editorial staff of X-Play is one of the finest in gaming news and they're stuck in website and podcasting obscurity, while a Playmate (fine to look at, but I'm sure she doesn't even do a lick of research about the stories she reads) hosts the news recap on Attack of the Show. I watch only the 90 minutes of studio programming on G4, but otherwise the network has been irrelevant to me since the botched slash-and-burn of TechTV they pulled off (yes, so many people are still bitter about that years later).
The number they should be aiming at; 31,000. That was the number of viewers for the premiere of Proving Ground a few months ago, just before Ryan Dunn's death. No show on cable should have 31,000 or less viewers in primetime unless you have the words FSN prefixing your channel name on a non-game night, or are a shopping or religious network. That, along with what I mentioned above, was why UFC decided to just sign with Fox and try to rescue Fuel TV (which at least has a set programming mission in extreme sports) rather than buying G4 itself. And why DirecTV doesn't carry it any longer.
