NEW YORK – The swan song of “American Idol” and heavy doses of comedy and sci-fi will mark Fox’s 2015-16 season.

The once-blockbuster singing contest, which launched the careers of Kelly Clarkson, Carrie Underwood and Jennifer Hudson, has seen its audience dwindle and age. “Idol” will return next year for its 15th and final season with returning judges Jennifer Lopez, Keith Urban and Harry Connick Jr., Fox said Monday.

Ten new series will debut next season on Fox, including the comedy-horror series “Scream Queens” from “Glee” producer Ryan Murphy and with veteran scream queen Jamie Lee Curtis in the cast.

New dramas will include “Minority Report,” based on Steven Spielberg’s futuristic film, and “The Frankenstein Code,” about a resurrected former lawman.

Fox and the other broadcast networks are unveiling their plans to advertisers in New York this week to lure them to spend on their programs.

There will be four new comedies, a comedy-horror anthology, four dramas and the return of “The X-Files,” which Fox is billing as a six-episode “event series.” Writer-producer Chris Carter, who created a landmark Fox series with “The X-Files” (1993-2002), will reunite with stars David Duchovny and Gillian Anderson to try to recapture the magic with a sequel starting in January.

“The X-Files” will have company in the sci-fi and fantasy camp. Futuristic “Minority Report,” based on the Steven Spielberg movie, will follow a duo trying to stop crimes before they happen.
