TV By The Numbers has the breakdown on CNN's Starting Point. They write:
CNN's new morning show Starting Point, which launched on January 2, 2012, notched the lowest monthly average total viewership (P2+) in February* for any CNN morning show in the past decade. Well below the time period numbers for February, 2011. More coffee!
A small consolation? It only had the third worst viewership in the advertiser targeted adults 25-54 demo.
