ABC/NBC

“American Idol” on ABC sunk 22 percent in TV ratings from its Sunday night premiere to Monday evening, when it first faced off against NBC’s “The Voice.”

But just how bad was the head-to-head beatdown by the NBC singing competition? Badly. Very, very badly.

“The Voice” posted a 2.3 rating among adults 18-49, which is the favorite age range for primetime advertisers. The show also hauled in 11.721 million total viewers. “Idol” had a 1.8 rating in the key demo and 8.359 million overall audience members.

Those Nielsen numbers mean that the NBC singing competition bested the ABC one by 28 percent in the main demo and a whopping 40 percent overall.

In the earlier-available overnight ratings, which count 56 key TV markets, each 15 minutes of the two-hour “Voice” received between a 7.1 and a 7.8 — “Idol” never topped a 5.8 and was as low as a 5.5 for three of the quarter-hours.

In other words, the two shows were never close at any point last night — and remember, this was just a pretty standard episode of “The Voice” versus the highly promoted Monday debut for “Idol” on ABC.

“The Voice” actually beat “American Idol” in every measured demo save one — the two shows managed to tie among men ages 18-34. ABC, which is touting time slot improvements from its pricey new property, is thanking its lucky stars for millennial dudes today.

14 Highest Selling 'American Idol' Alumni of All Time (Photos)

"American Idol" returns on March 11, and we couldn't be more excited. That's because it's the rare reality show that has actually produced some bona fide pop stars, hit-makers and even an Oscar winner.

Underwood is the only solo country music star to have a No. 1 hit on the Billboard Hot 100 and 14 No. 1 hits on Billboard's country charts. Her last album, "Storyteller," came out in 2015, so by the time her next one drops, her lead may go up yet again.
