A winner emerges on the two-hour finale of “The Voice” (8 p.m., NBC). For a moment, it looked like this series might just overtake “American Idol” as America’s favorite singing competition, but its audience dwindled as the season progressed.

Talent shows are all about finding the next new star — until their finales, when it’s time for well-established stars to crowd the stage. Look out for Justin Bieber, Flo Rida, Lady Antebellum, and Daryl Hall and John Oates. I guess the name Hall & Oates was taken.

• “New Girl” (8 p.m., Fox) also ends its first season. The roommate comedy wraps up freshman year with a moving-day episode. One of the more well-received comedies of the year, “Girl” enchanted critics and viewers with Zooey Deschanel’s sweet, goofy, nerd routine.

The real mystery was how long it could last. Ratings for “Girl” have steadily declined. It didn’t help that the series seemed to vanish for weeks on end when it was first broadcast. It also airs against “Dancing With the Stars” and “NCIS: Los Angeles,” two established series. All the same, “Girl” proved that you could make a comedy about young 20-somethings and not dwell entirely on vulgarity (“2 Broke Girls” on CBS) or brittle cruelty (“Don’t Trust the B– in Apt. 23” on ABC). Congratulations to Fox for airing the most humane new network comedy of the year.

• Not even a lead-in from the two “NCIS” ratings machines did much to drive viewers to “Unforgettable” (9 p.m., CBS). This police procedural about a woman blessed (or perhaps cursed) with an amazing memory ends its first season with Carrie thinking she’s found her sister’s killer.

CBS renewed most of its shows some months back. “Unforgettable” was not on the list. That doesn’t mean it has been canceled. But if it does return, look for it to lose its plum spot and migrate to Friday nights, where shows like this are put out to pasture.
