Is it only one night? Yep.
Is it still very, very early? Of course it is.
Is NBC being propped up at the risk of tiring out the Voice too soon? Maybe.
Did NBC have the Olympics and Sunday Night Football to pummel tens and millions of people with promos? Yes, it did. But NBC could've had all that and still wound up in last place on the first night of the new TV season and nobody would've said "how could that have happened?"
Last night NBC led every single half hour in adults 18-49 except at 8:00p where it tied with How I Met Your Mother. Every. Single. Half. Hour.
On the night it bested CBS by 48% with adults 18-49, ABC by 53% and Fox by 135%. You read that right!
On opening night a year ago (9/19/11) where CBS was propped up by curiosity about Kutcher replacing Sheen, NBC was last every half hour with its line-up of The Sing Off and The Playboy Club.
It is only one night and its still early, but to go from worst to first on opening night in just one year has to feel pretty good for NBC.
