G4techTv 

The act of buying out a innovative channel, merging it with an abysmal channel, laying off all the former channel's workers and canceling most of the shows. So that the abysmal channel's longevity is increased. So that the greedy bastard executives of the abysmal channel will be able to keep their jobs.

Random guy 1: "Dude, did you hear Viacom bought out TMC and is merging it with MTV???"

Random guy 2: "Damn, Viacom pulled off a G4techtv."
