Comcast has agreed to buy TechTV and is folding it into their own network, G4. Additionally tonight was Leo Laporte's last night as host of The Screen Savers. Sad to see Leo taking a diminished role on TSS, personally I'd rather see him give up Call for Help, but I understand that there's not really a good alternative hosting option for CFH like there is with TSS.
I can't say I've ever seen one show on G4 that I liked, so let's hope they don't mess with TechTV's shows too much. At the very least I think they need to keep Call for Help, The Screen Savers, Tech Live, Fresh Gear, and X-Play(which is a better gaming show than anything G4 has).
