— Pre-launch costs of £5.7 million (it was conceived as iMP in 2005 before launch in 2007).
— Development costs of £4.8 million over four years to fiscal year ending March 2011.
— Other current costs of about £4 million per year for transcoding, metadata, editorial oversight, support.
On these figures, developing iPlayer will have a cost of £10.5 million between 2005 and 2011, plus about £12 million in operation costs, making for a lifetime total of at least £22.5 million by next March.
The listed current ongoing development and operational costs work out at £5.2 million on an annualised basis.
Some further iPlayer-related costs are accounted for in other budgets, says the BBC. And the corporation is declining to reveal additional related licence costs paid to contractors like Microsoft (NSDQ: MSFT) and Siemens, citing commercial confidentiality.
The online service licence issued to the BBC by the BBC Trust in August 2009 had already mandated and disclosed the £4.8 million, four-year development costs and an annual operation budget of £3.9 million; it’s the pre-launch costs we had not previously seen alongside them.
