BBC Worldwide America exec Paul Telegdy is in talks to take on NBC’s top reality job.

Network insiders confirm Telegdy is expected to replace Craig Plestis, NBC’s exec VP for alternative programming, development and specials.

Plestis’ departure from the NBC post had been rumored for weeks, but the network dismissed the talk up until now.

Shuffle reps the latest alternative department switch at the networks, following CBS’ recent decision to replace Ghen Maynard with Jennifer Bresnan.

Like CBS, NBC has struggled recently to come up with a new crop of reality hits. Recent stabs, such as “America’s Toughest Jobs,” have come up short.

Telegdy, meanwhile, is no stranger to the Peacock, having exec produced the reality competitions “Clash of the Choirs” and “Grease: You’re the One That I Want” for the network.

If Telegdy is departing BBC Worldwide’s North American operation, it comes just a month after BBC drama topper Jane Tranter was brought in to handle joint responsibility for production in Los Angeles and New York, alongside Telegdy. Tranter was named exec VP of programming and production, while Telegdy was tapped exec VP of TV sales and content/production.

With Telegdy’s exit, Tranter will likely oversee the division herself, reporting to BBC Worldwide America prexy Garth Ancier.

Telegdy has headed the BBC’s production efforts in the U.S. since 2004, overseeing the U.S. adaptation of “Dancing With the Stars” for ABC (as well as the spinoff, “Dance Wars: Bruno vs. Carrie Ann”) and CBS’ short-lived “Viva Laughlin” as well.

As for Plestis, the exec’s next move hasn’t yet been determined. He’d been busy at work putting together a variety special starring Rosie O’Donnell — “Rosie Live” — slated to air Nov. 26.

Plestis has been with NBC since 1997, first joining as a freelance writer-producer at the NBC Agency. He later moved to the alternative programming side, handling shows like “The Apprentice.” He’s served as exec VP since March 2007; besides reality series, he handles specials including the Golden Globe Awards.

Spokespersons for BBC Worldwide and NBC declined comment.
