The ratings struggles continue for CNN, where “Anderson Cooper 360” recently notched an unhappy milestone. TVNewser reports that the show posted its lowest ratings since it moved to the 8 p.m. time slot in August 2011.

The CNN show’s decline comes amid a wider loss of viewers for the network. As previously reported, CNN’s shakeup by new chief Jeff Zucker has failed to produce positive results, as the cable news channel’s ratings appear to keep falling.

“Anderson Cooper 360” drew 255,000 total viewers on Friday and 58,000 in the 25-54 demographic, a low since August 2011. Fox News’ “The O’Reilly Factor,” meanwhile, averaged 2.42 million total viewers and 447,000 in the 25-54 demo, the piece adds.

“Compared to the same day last year, Cooper’s program was down -60% in total viewers and -67% in the demo,” the article notes.

TVWeek Open Mic writer Chuck Ross blogged last week about Zucker’s efforts to resuscitate CNN’s ratings by transforming the news network.
