NBC has unveiled plans for expanded versions of its singing competition series “The Voice.” TVbytheNumbers.com reports that show will expand to two hours for the live June 10 and June 17 episodes.

“For the June 10 program, the remaining artists will sing for both the coaches — Adam Levine, Shakira, Blake Shelton and Usher — as well as nationwide audience. At-home viewers will begin voting at the show’s conclusion to see who moves on and who is eliminated,” NBC said in a press release.

The remaining artists will compete one last time during the June 17 program before the champion is unveiled June 18.

The story notes: “For the recently completed 2012-13 traditional television season, the Monday edition of ‘The Voice’ averaged a 5.2 rating, 14 share in adults 18-49 and 14.4 million viewers overall, making it the #3 primetime series on the broadcast networks in adults 18-49, the #2 entertainment series and the #1 reality series.”

The win by “The Voice” among reality shows reportedly marks the first time since the 2002-2003 season that Fox’s “American Idol” has failed to finish No. 1 in the key 18-49 demo.
