CBS has ordered additional episodes of all three members of the CSI franchise. This brings CSI: Miami up to 24 episodes, and CSI: Crime Scene Investigation and CSI: New York now have 23 planned episodes at this point. This news comes as the network announces that they are lowering the season order for Friday night series Numb3rs from 22 to 16 episodes. There is a rumour that Flashpoint will take the 10:00pm timeslot on Fridays starting in February, but this has not been confirmed.
