YouTube's got talent, and 12 acts will get a chance to prove it. After "America's Got Talent" opened online auditions, thousands of people and groups submitted their videos on YouTube. Producers chose 40, and YouTube voters then narrowed that list to 12, with 10-year-old opera singer Jackie Evancho of Pittsburgh in the No. 1 spot.

Evancho will perform tonight (8-10 p.m. Tuesday, Aug. 10, on NBC)  along with the 11 other top finishers. On Wednesday's episode (same time), four acts from the YouTube performance show will move on to the Aug. 24 semifinals.
