First base

Jeff Zucker formally arrived at the helm of CNN in late January - so it would probably be fair to set the first quarter viewing figures of 2013 as his baseline.

In total viewers, CNN was down 22% in primetime compared to Q1 2012. In the lucrative 25 to 54 year-old demographic, CNN was down 31% in primetime. "Piers Morgan Live” was down 2% in total viewers, and 18% in the demo compared to last year.

These are the key figures for Zucker to improve on - total viewers in primetime 590,000 - 174,000 of them from the 25-54 year-old group.
