I’ve learned that CBS is finalizing deals for back orders to rookies Person Of Interest and Unforgettable. Neither of them has been the breakout hit that CBS’ new comedy 2 Broke Girls has been (that series was given an early full-season order a couple of weeks ago), but they have both performed solidly in their time slots and are coming off ratings upticks. Unforgettable (2.5/5) on Tuesday was up two tenths from last week, while Person Of Interest last Thursday drew a 2.7/7 in 18-49 and 12.6 million viewers, up two tenths from the previous week in the demo. It benefited from a Big Bang Theory repeat as a lead-in vs. How To Be A Gentleman the week before.
