TV audiences had no shortage of Jennifer Lopez audiences on Thursday night. And while they seem to have favored the familiar (American Idol), the multihyphenate's new NBC vehicle didn't do half bad.

After new episodes of Heroes Reborn and The Blacklist, Shades of Blue managed to build an audience at 10 p.m. — no easy feat. The cop drama averaged a 1.8 rating among adults 18-49, up two-tenths of a point from its Blacklist lead-in, and 8.6 million viewers. To say that's NBC's biggest debut in the hour for some time would be an understatement. The network has struggled in recent years to bring a crowd.

The second night of American Idol, again airing two hours, averaged a 2.7 rating among adults and 10 million viewers, was only slightly down from Wednesday's opener. It gave Fox a win for the night, though the show was obviously no match for The Big Bang Theory.

CBS' own Thursday premiere, comedy Angel From Hell, did not pull quite as much of a crowd as Shades of Blue. The sitcom nabbed a 1.6 rating among adults 18-49 and 8 million viewers, in line with what 2 Broke Girls has been bringing to the 9:30 p.m. slot. Its lead-ins were largely unmoved. The Big Bang Theory, Thursday's de facto winner, pulled a 3.8 rating among adults 18-49. Steady Life In Pieces (2.2 adults) and Mom (1.8 adults) followed.

Elementary jumped to a season high in the key demo, rising 20 percent to a 1.2 rating among adults 18-49.

Over on ABC, a Thursday outing of Beyond the Tank was steady with a 1.0 rating among adults 18-49. The debut of My Diet is Better Than Yours, however, was a clunker. The two-hour premiere only pulled 2.4 million viewers and a 0.7 rating among adults 18-49.
