About 10.3 million watched Sunday's two-hour Idol premiere, which is on par with The Voice's debut weeks earlier and bigger than anything ABC aired last week, including The Bachelor finale and Grey's Anatomy. The last Fox season of Idol premiered to nearly 11 million viewers in 2016. Meanwhile, only 4.4 million watched the two-hour O.J. Simpson: The Lost Confession? Still, Sunday's launch had the lowest demo rating for an American Idol debut, about 20% below the previous low in 2016.
