(MEDIABISTRO) — Monday’s 9pmET timeslot on CNN drew 181,000 total viewers, the lowest for the time period since at least Oct. 1, 1991, as far back as Nielsen electronic records go. Anderson Cooper anchored a second live hour of AC360 at 9pm.
It was also the lowest rated hour of CNN’s entire day. Cooper finished fourth in the hour behind Megyn Kelly on Fox News, Rachel Maddow on MSNBC and Dr. Drew Pinsky on HLN, in both total viewers and the demo.

CNN’s 9pmET hour was the longtime home of Larry King and, until earlier this year, Piers Morgan. Most nights, CNN’s new non-fiction shows from Lisa Ling, Mike Rowe and John Walsh fill the timeslot. But Mondays have included a second live hour of Cooper.
