More than 7 million people watched as Leanne Mitchell was crowned the winner of BBC singing reality television show, "The Voice," the British network said.
"It gives me confidence that there is justice in this world," Jones said of the win.
That makes "The Voice" the highest-rating debut for a BBC program on record, said a BBC spokeswoman, whose name was not reported.
Ratings peaked earlier in the season at more than 10 million viewers, but had dropped to 4.5 million by last week, BBC reported.
BBC One controller Danny Cohen said producers will look for ways to improve the series in the future.
"We'll take away a few things from the live shows to tinker with for series two," he said.
