Methodology used to calculate the BBC Global Audience Measure

The request was partially successful.

Hi there,

I read with interest the recent announcement of the latest BBC Global Audience Measure, including Facebook and YouTube data for the first time. ("BBC’s combined global audience revealed at 308 million", http://www.bbc.co.uk/mediacentre/latestn...)

I'd like to understand the methodology that was used to calculate this, in particular how the contribution of YouTube and Facebook is calculated, eg. how double-counting's avoided, what assumptions are made, what data sources are used and similar.

Could you please share any documents or guidelines that:
a) show the full calculations used to reach the figure of 308 million (possibly an Excel spreadsheet, for example)
b) outline the methodology / business rules for calculating audience measures, particularly online content

Please let me know if I can clarify this request at all.

Many thanks for your help!

Cheers,

JM Deamer

Full request refused as gathering the data would exceed the £450 cost limit, but they've invited me to submit another request in 6 months time when this will be available anyway.

Under section 16 of the act (duty to provide assistance) though, they've provided a very helpful and comprehensive answer that provides much of what I needed anyway.

Cheers BBC!
