CNN’s April ratings hit the network’s lowest levels in more than a decade, with the show "Anderson Cooper 360" especially hard-hit, reports the Los Angeles Times’ Show Tracker.

Ratings for "360" slid 26% compared with the same period a year earlier, with only 522,000 total viewers tuning in on average, the story notes. CNN’s total-day viewership slumped 21% to 357,000 viewers, the worst performance for CNN since August 2001.

The cable news leader continues to be Fox News, which was up 2% with a total-day average of 1.1 million, well ahead of second-place MSNBC, which was even with 425,000.

Asked for comment, a CNN representative said, "News ratings are cyclical," the story notes.

Other CNN shows were also hit, with "Starting Point" down 26%, "Erin Burnett Outfront" down 22% and "John King USA" down 24%.
