Back in its regular Tuesday slot, American Idol was the big winner on Tuesday night, beating last Thursday’s results show by 5 million viewers in its second hour. Meanwhile, The Biggest Loser: Couples lost 14 percent of its 8-9 p.m. viewers from last week’s new episode — no doubt because it had to compete with Idol this week. And part 2 of The Bachelor: After the Final Rose lost almost 40 percent of its Monday night audience, but still won the coveted 18-49 age group for its time slot.
