NBC is in talks with FremantleMedia to resurrect “American Idol,” Variety has learned. According to sources with knowledge of the discussions, NBC has been pitched a revival of the long-running singing competition by producer Fremantle and is now mulling options for how to integrate the show into its programming slate. One possibility being considered: cutting NBC’s existing singing competition “The Voice” from two cycles a year to one. Fremantle has been shopping an “Idol” revival in recent weeks, with NBC emerging as the leading candidate to become the new home of the long-running singing-competition series. Sources emphasize that talks are ongoing, and no deal is yet in place.
