At £11 million a year, The Voice is by far the channel's biggest format purchase and will be its most expensive entertainment show ever, costing around £500,000 per hour aired.
With £1 million spent on coaches - including £500,000 on hiring Will.i.am alone - the BBC will be hoping the show brings in big numbers when it launches this weekend.
"If it doesn’t get more than ten million viewers, as Call The Midwife did, then it’s nothing short of an expensive disaster," a source tells the Daily Mail today.
But unfortunately for the BBC, Simon Cowell and ITV have played dirty by scheduling the return of Britain's Got Talent on the same night.
While it won't air until 8PM - an hour after The Voice starts - the two shows will still clash for 20 minutes.
"Simon’s view is that they started this war by paying so much money for The Voice in the first place and we should be throwing everything possible at it to kill it off," an insider told the newspaper.
The Voice UK starts on BBC One tomorrow at 7PM.
