Since the week of March 30, Cuomo has dropped from first in his 9pm time slot among cable news hosts to bottom of the barrel, last week averaging just 440,000 daily viewers in the age demographic prized by advertisers.
Cuomo's stunning ratings nosedive came after interviews with his brother, New York Governor Andrew Cuomo, in lighthearted segments that were widely panned as ratings stunts amid the coronavirus pandemic.
Though all cable news saw something of a drop-off in viewership in May, as viewers seemingly grew weary of the pandemic coverage, Chris Cuomo's decline was sharper than his time slot competitors, MSNBC's Rachel Maddow and Fox News' Sean Hannity.
Chris Cuomo's ratings peak came the week of March 30 when he announced that he had tested positive for coronavirus and was isolating in his basement, beating out Maddow and Hannity with 862,000 daily viewers in the 25-54 age demographic.
Since then, his ratings have dropped 49 percent in the demo and 35 percent overall, while Maddow is down 17 percent in the demo and 7 percent overall. Hannity has dropped 38 percent in the demo and 12 percent overall.
Last week, Chris Cuomo dropped below Maddow in the demo for the first time since March 2. Maddow had 498,000 daily average viewers in the demo and Chris Cuomo had 355,000.
Chris Cuomo's sibling interview segment last week drew heated backlash over its lighthearted tone, coming as his brother Andrew Cuomo faced tough questions over a March order requiring nursing homes to accept patients recovering from coronavirus.
The virus has since raged through New York's nursing homes, killing more than 5,800 elderly and vulnerable residents.
