The dip in ratings have more to do with the time of the year rather than the show itself. Just about every series on every network has been down in the ratings since the new episodes returned for May sweeps. The old broadcast standard is broken. With an earlier Daylights Savings Time, viewers get used to doing other things during an endless parade of repeats in March and April, and they just aren't returning in May. According to deadline.com, the future of the CSI spinoffs may be decided today. Bruckheimer has invited Les Moonves and Julie Chen as his guests for the Kentucky Derby, and there is no doubt that they will be discussing the budgets for each show and what is necessary in order for them to return. I know all three CSI's swept the most watch drama in the world category for the upcoming Monte Carlo TV Festival, and CBS could possibly still make a profit if they produced another season of both shows. Personally, I would love to see both of them get 13-episode final season orders, and CBS could air them in their original Monday and Wednesday timeslots during December, January, and February to help cut down on the amount of H50 and CSI repeats next season.
