Mistake for BB12 launch plan
 

To get more/new viewers, BB12 should launch the same night as CBB finishes. As impractical as it seems, a lot of celebrity big brother viewers don't bother with the regular show, and if it ran over in the same night many would watch just to see the new housemates and possibly get sucked in by first-night plots.

I know a lot of people who watch CBB but not BB; this would be an excellent opportunity for new recruits.

I agree, but you have to think weather people will want to watch that much in one day
