Peacock will begin the sixth season of “America’s Got Talent” with a two-hour episode May 31. Show has been a staple for the network during the summer when reality floods the broadcast nets.

“Talent” will run two hours on Tuesdays and 60 minutes Wednesdays, similar to the formula “American Idol” began on Fox. Howie Mandel, Sharon Osbourne and Piers Morgan return as judges while Nick Cannon remains host.

As for “The Marriage Ref,” the Jerry Seinfeld exec produced reality skein — in which couples discuss their problems to a voting audience who determines if the husband or wife is correct — was supposed to begin again in mid-March in an 8 p.m. Sunday timeslot leading into “Celebrity Apprentice.” However, NBC decided to put “America’s Next Great Restaurant” in that hour and bumped “The Marriage Ref” back to summer.

Other shows announced for summer but don’t have firm start-up dates include gameshow “It’s Worth What?,” newly acquired Israeli import “Still Standing” and adventure dating skein “Love in the Wild.”

NBC has high hopes for singing competition “The Voice,” which will launch April 26 and continue through the end of June.

On the scripted side, “Law & Order: Criminal Intent” will begin its final broadcast season May 30.

“We want to make it clear that NBC considers the summer as an important part of its overall season and will continue to offer a varied lineup of original programs,” said network entertainment chairman Robert Greenblatt.

NBC also has a handful of comedies in the can that may pop in summer. Hourlong “Love Bites was supposed to be originally be on the fall calendar but was pushed back because showrunner Cindy Chupack left the series and actress Jordana Spiro had other commitments.

There’s also singlecam half-hour laffers “The Paul Reiser Show,” from Warner Bros. TV, and “Friends With Benefits,” from creators Scott Neustadter and Michael H. Weber and Twentieth Century Fox.
