‘America’s Got Talent’ Season 21 Episode 20 Release Date, Time, Where to Watch and What to Expect

The competition on ‘America’s Got Talent’ is intensifying, with Season 21 approaching one of its most crucial nights. The live shows kicked off on August 18 on NBC, featuring Quarterfinals that run until September 8, followed by Semifinals on September 15 and 16, and culminating in the Finals and Finale on September 22 and 23.

For those keeping track of when to tune in, how voting works, and which acts remain in the competition, this is the moment when the season truly narrows down. With the judges’ power now shifted to the viewers, the next episode carries significant weight for the Top 44 hopefuls vying for a place in the finale.

The Live Semifinal Performances are set for Tuesday, September 15 at 8 p.m. ET, followed by the Live Semifinal Results the next night, Wednesday, September 16, also at 8 p.m. ET. This two-night format has become standard for ‘America’s Got Talent’ this season, allowing one night for performances and a separate night dedicated to revealing who moves forward.

This follows the September 8 Quarterfinal episode, which aired as a special three-hour live event featuring immediate voting and instant results, with no new episode airing the following day. This scheduling adjustment was due to NBC’s football coverage, but it also meant condensing an entire week’s worth of drama into a single marathon broadcast before heading into the Semifinals.

Once the Semifinals conclude, only one round remains. The Live Finals are scheduled for Tuesday, September 22, with the Live Finale on Wednesday, September 23. This is when ‘America’s Got Talent’ will announce its Season 21 winner.

Fans can catch new episodes of ‘America’s Got Talent’ on Tuesdays at 8/7c on NBC, with episodes available for streaming the following day on Peacock. Specifically for the Semifinals, the performance episode airs live on NBC before becoming available to stream on Peacock, while the results episode follows the same pattern on Wednesday.

Voting for this round operates differently than in previous seasons, as audiences now determine which acts advance rather than the judges making saves or granting wild cards. Viewers can vote through the NBC website, the AGT app, or by commenting on the show’s TikTok posts, with up to ten votes allowed per method before voting closes each Wednesday morning at 7 a.m. ET.

This expanded voting window, particularly the inclusion of TikTok comments as an official method, has sparked considerable discussion among longtime fans of the show.

In the Semifinals, twelve acts will perform, and America will vote to advance six of them into the Finals, joining the acts that secured their spots through the Live Golden Buzzer. Additionally, the judges will collectively hit a Golden Buzzer for one more Semifinalist, bringing the total number of acts moving on to the Finals into double digits.

This season has heavily utilized the Golden Buzzer as a competitive tool. While it retains its Live Golden Buzzer format, Wild Cards, Saves, and other judge-driven advancements have been removed, placing the audience fully in charge of who continues in the competition. This shift has heightened the stakes for every performance, as there is no safety net if a judge personally favors an act but the public vote does not align.

The journey to this point has not been entirely smooth for the judging panel either. Simon Cowell has been absent from the live judging panel for several weeks while recovering from back surgery, with guest judges stepping in during his absence. Kenan Thompson filled in for the third Quarterfinal round, while Heidi Klum returned as a guest judge for the final Quarterfinal round.

The Top 44 Acts advancing to the Live Quarterfinals showcased a diverse mix of singers, dancers, comedians, magicians, stunt performers, viral newcomers, and established entertainers selected by the judges. This variety has been evident throughout the Quarterfinal rounds, leading to a genuinely unpredictable Semifinal night with so many different talents still in the running.

By the time voters reach the Finals, the competition will be significantly narrowed. The Finals of Season 21 are set to take place at the Pasadena Civic Auditorium, with ten acts competing for the one million dollar prize. Reaching that stage requires surviving both the judges’ scrutiny in earlier rounds and the unpredictable nature of a fully audience-driven vote.

Terry Crews continues to host, guiding contestants and viewers through a season filled with format changes and scheduling challenges. With the condensed Quarterfinal finale, rotating guest judges, and the new TikTok voting option, Season 21 has provided fans with plenty to discuss even before the Semifinals commence.

With the Semifinal performances airing on September 15 and results following the next night, the pressure is on the twelve remaining acts to leave a lasting impression. Which act do you believe has the best chance of winning America’s vote and securing a spot in the ‘America’s Got Talent’ Season 21 finale?
