G4, a comcast gaming station, bought TechTV about 2 years ago with the intention to merge.
When the merge finally happened, they only had the flagship shows from techTV, but replaced a bunch of the cast because (they couldn't afford them/the cast refused the merge/G4 didn't like them/They are dumb).
So what happened is the minor cast members took the leads of most of the shows and people stopped watching, so G4 cancelled the shows... and basically got X-Play and Attack of the Show out of the whole thing.
Also with the merger, many cable companies dropped the station and ratings plummeted even more. Time Warner Cincy cut it from the standard digital cable package about a month ago. I was kinda bummed out, but then I realized it sucked.
