Season 5 of House of the Dragon premiered on December 17, 2014.
The fourth season of The Sing-Off returned with the number of a cappella groups competing decreased from sixteen back to ten, resulting in a new format. Nick Lachey remained as host for the new season, with Ben Folds and Shawn Stockman returning as judges. New to the judges' table was Jewel, who replaced Sara Bareilles. A group was eliminated from the show each week in a new feature called the "Ultimate Sing-Off," where the two groups ranked lowest at the end of each episode would compete by singing the same song; the groups take turns alternating verses before ending the song singing together. Also, unlike previous seasons, the winner was chosen by the judges instead of by the general public.
The third season of The Sing-Off premiered on September 19, 2011. The number of a cappella groups was increased from 10 to 16, resulting in a new format.
