In the morning, the network got word from Nielsen that — after Wednesday night’s Top-5 performance show — “American Idol” had regained its throne as the No. 1-rated entertainment series among younger viewers, who are the currency of broadcast TV ad sales. To accomplish that, “Idol” had to edge past NBC’s singing competition, “The Voice.”

This season, “The Voice” had toppled “Idol,” which previously was No. 1 every season since its first in-season edition nearly a decade ago. (“Idol’s” first in-season edition was actually its second round of competition. The series, now in its 11th season, premiered as a summer show in June of 2002; the “official” TV season runs from mid-September until late May.)

Regaining its throne is an accomplishment for “Idol,” which is ancient in reality-TV years. “The Voice,” now only in its second season, debuted this season right after the Super Bowl and attracted a whopping 21 million 18- to 49-year-olds — a huge number to dump into its season average.

Through this week, “Idol’s” Wednesday performance show is now averaging 7.941 million 18- to 49-year-olds for the season. “The Voice’s” Monday performance show is averaging 7.815 million people in the age group.
