"With more than 3,000 episodes aired between them, we have more than enough great material to honor these innovators and their amazing contributions as we bring both shows to a close."TVGuide.com says there is talk that G4 may be looking to partner with Esquire or another men’s magazine like GQ as it moves forward into “more upscale, sophisticated guy TV space.” The network may be renamed G4Men, among other possibilities.
